Neutral versus acetoxy silicones



In chemical terms, various substances are understood either to be alkaline, neutral, or acidic. Silicones that are used for construction purposes are similarly divided into categories according to the chemicals that are released in the curing process, and are respectively neutral or acetoxy.

Silicones are one of the best-known forms of sealant. They can be utilised for a number of applications due to their elasticity, movement capability in a joint, and high UV and weather resistance. Below we will take a closer look at these two silicone types and their applications.

The smell is not the only difference

Both neutral and acetoxy single component silicones cure due to the presence of air humidity. Although they may have a similar appearance after curing, they have also a number of differences about which one should be aware of before using them, so that the most appropriate product can be selected according to the required application.

For many people, the difference between neutral and acetoxy silicones is simply in the smell. As can be understood by the name, acetoxy silicones that emit acetic acid have a strong vinegar smell during the curing process. Neutral silicones emit compounds that have a specific sweet aroma or are mainly odourless. This depends on whether the curing system is oxime or alkoxy.

The differences between the two groups of silicones is not limited just to odour. Acetoxy silicones are inappropriate for use with uncovered metals because acetic acid evaporates during the curing process and may cause corrosion. Accordingly, it is not recommended to use acetoxy silicones with cement-based products (such as concrete, plastered surfaces, construction blocks, etc) because they will not provide enough adhesion with the surfaces. Neutral silicones provide very good adhesion to the aforementioned materials and therefore they are usable for a significantly wider range of applications.

In which cases should one or the other curing system be preferred?

The simple answer to somebody with limited experience is to use the neutral silicone when in doubt. This relates back to the reasons mentioned above. Discarding special products for specific applications, it could be said that neutral silicones work just as well in places where one would like to use an acetoxy silicone. The same may not be applicable the other way around. Sealing connections between metal surfaces, window sills, ventilation appliances, concrete façade joints, and masonry are just some examples for which a properly applied neutral silicone works correctly, but the acetoxy silicone does not.

It should not be forgotten that for some applications the acetoxy silicones can superbly fulfil expectations and are the proper choice. For example, sealing in sanitary rooms, for which the mainly-used materials include ceramic tiles, glass, and anodised aluminium, the acetoxy silicones fit perfectly and they even provide advantages in terms of costs compared to neutral silicones. One additional advantage of using acetoxy silicones becomes apparent in glass-to-glass joints, for example sealing glass partition walls- acetoxy colourless silicones are significantly more transparent when compared to similar neutral silicones.

In summary, when it comes to selecting the correct silicone, the exact application area and materials which the silicone should adhere to, should kept in mind. More detailed information is available from our sales representative.

Internal product development is identified and recognised


Foam on glass Edit veebi

Wolf Group|Krimelte has contributed to product and tool design development for years, in order to add value to the joint fillers and building adhesives developed by the company.

In 2011, Krimelte received the Design Applier 2011 award from Enterprise Estonia, the Estonian Chamber of Commerce and Industry, and the Estonian Employers’ Confederation. The recognition was for an internationally patented applicator developed for PENOSIL EasyGun foam. Building foam applied by a foam gun or straw applicator usually has variances in the structure or yield. However, the EasyGun foam can boast uncompromised quality and can be successfully used with a special applicator.

In 2018, the spatula provided with the sealants of the PENOSIL EasyPRO range reached the final round of best engineering design at the Bruno Product Design Award from the Estonian Association of Designers. The challenge for the spatula was to combine industrial production, functional design, ergonomics and the best possible user experience. Of original design creations, economic success can also be expected from the newest achievement of production technology: PENOSIL EasySpray insulation foam with a special spray nozzle (product in the photo, read more about the product here).

As Wolf Group|Krimelte consistently applies strategic design, Enterprise Estonia asked Tiit Arro, the Marketing Director of Wolf Group|Krimelte, to join the jury of their product development programme “Design Master Class”. The main goal of the jury consisting of 6 members was to evaluate the potential, ideas, prototype and activities of the work done by the participating companies in six months. The participants in the programme were both Estonian and top global performers, including Elkdata, Radis, Sarkop, Thermory and Creditinfo Eesti, among others. The 10,000 euro prize for developing their product development ideas was awarded to Factory Seven OÜ. It is a company specialising in ventilation products, which created an original design, good functionality and a modular kitchen hood with LED lighting under the programme. “Factory Seven clearly showed how important customer interviews and one-to-one communication were for product development in order to achieve the best user experience,” Tiit Arro said, in highlighting the advantages of the winner. “Their presentation was highly engaging and expanded my perspective as a member of the jury, as well as confirmed my current beliefs. The case study of furniture producer Radis from Germany was also interesting and made every jury member consider whether it was easy to contact the company they worked for in order to place an order,” Arro admits.

PENOSIL- a brand visitors expect to see at Baltic trade fairs


imporatants Picture

For almost 10 years the Wolf Group has been taking part in spring trade fairs around the Baltic States with the PENOSIL trademark, showcasing new products and all-in-one solutions and developments. In March and April 2019 the group once again appeared with a uniform stand design and message at fairs in Estonia, Latvia and Lithuania.

The construction industry trade fairs House (Latvia), Estbuild (Estonia) and Resta (Lithuania) focus on promoting innovative technology and the latest skills, experience and know-how. Eva Iškova, the Sales Manager of Penosil Estonia, says that although visitors to construction fairs have very different profiles, the proportions of professional and home clients are more or less equal. “The target groups you see at these events are store representatives – at the management level and the level of the retail sales department – as well as professional sales experts, small businesses, self-employed workers in the industry and ordinary visitors,” she explained. Krimelte Lithuania Sales Manager Sigita Gasparaviciene says that while visitor numbers are slightly down overall in Lithuania, the contacts that people are making are more valuable and that all of Krimelte Lithuania’s existing and potential future partners have been represented at the events.

Know-how and product development

The PENOSIL trademark champions contemporary sealing work and solutions and contributes to debates on issues arising from the energy efficiency directive. We have developed a number of all-in-one solutions for energy-efficient window installation and a range of products that helps to solve the heat and humidity technology issues accompanying window assembly. Airtightness was in focus at the trade fairs. The importance of airtightness is illustrated, among other things, by the fact that in the case of nearly zero-energy buildings, proving airtightness post-construction by measuring it has become inevitable. Using the PENOSIL Airtightness Simulator designed and built in the Wolf Group, every visitor to our stand could see for themselves when and how air leakages occur and how such situations can be avoided. The visitors had a wide range of questions for us, such as whether sealing tape should be used in addition to PU-foam and why joints should also be covered with a layer of mastic. The Wolf Group has produced brand- and product-based brochures, videos and web solutions covering all of these topics for clients to peruse at home.

A big hit in the making

PENOSIL EasySpray foam was introduced and demonstrated for the first time at this year’s events. In rooms or construction elements with insufficient insulation, which in the climate of Northern Europe makes itself known through frosted surfaces, the solution is fragment insulation. From the point of view of cold bridges, critical spaces include sheds, garages, attics, basements, balconies, tanks and piping. PENOSIL EasySpray single-component insulation foam is meant especially for these applications. Instead of traditional bulky insulation boards and fasteners, insulation can be conveniently made on site with the help of spray foam. Thanks to its unique spray applicator, surfaces which are difficult to access and uneven surfaces can be isolated. PENOSIL EasySpray foam has nearly zero isocyanate content, which means that applying it is safe for both your health and the environment. Krimelte Latvia Key Account Manager Kirills Sokolovs says the foam was a big drawcard at the trade fairs. “To see up close how the EasySpray foam works and how to apply it, and to get the chance to try it for yourself, brought lots of people to our stand from all over the hall,” he said. The PENOSIL managers from Estonia and Lithuania confirmed that the same was true of the events in their countries.

Adhesives which have proven their worth

We are also pleased to report that the PENOSIL SpeedFix adhesive concept, which comprises nine different construction adhesives, has piqued the interest of professionals. Visitors to the trade fairs asked us many questions not only about the biggest-selling product in the SpeedFix range – the multi-purpose foam adhesive – but also about acrylic, solvent-based and hybrid adhesives, their bonding surfaces and adhesion techniques.

PENOSIL is the main brand of the Wolf Group, which sales units are located in Estonia, Latvia and Lithuania.

Wolf Group | Krimelte acquired 100% ownership in the Spanish construction chemistry company Olive Quimica S.A



On April 30, Krimelte OÜ acquired 100% ownership interest in the Spanish company Olivé Química S.A, which is engaged in the development, production and sale of silicones, sealants and adhesives. Following the transaction, Jaan Puusaag, the founder and a member of the management board of Wolf Group | Krimelte will continue as the CEO of the company.

Krimelte OÜ has been the major shareholder of Olivé Química S.A since 2014, when a 75% holding was acquired in a family business which had been in operation for 45 years. The ambition was to enter the Spanish and Western European markets, along with strengthening the product portfolio and export geography.

According to Jaan Puusaag, achieving 100% ownership in the Spanish subsidiary was a strategic step for Wolf Group | Krimelte in order to assume a stronger position on the home markets of Olivé Química, which besides Spain, includes Portugal, France, the United Kingdom and export markets in more than 50 countries. Olivé employs over 100 people and last year the consolidated turnover of the companies accounted for nearly 22.5 million euros.

“With the acquisition of Olivé Química S.A, Krimelte has demonstrated its determination for more active and further development of the Olivé trademark, production and sales companies and its responsibility towards the employees, partners and customers,” said Jaan Puusaag, who has been coordinating the everyday activities of the company for the last 6 months. “On behalf of the management board, I would like to thank everyone, who has supported us in this process,” he added.

According to Peeter Tohver, the Chairman of the Management Board at Wolf Group | Krimelte, the transaction has created excellent conditions for expanding on the Spanish and Western European target markets. The transaction opens up new opportunities that contribute to the strengthening of the group’s position as the developer of sealants and adhesives, and turn it into an even more attractive partner for its customers throughout the world, who include industries, large construction projects, design offices and retail stores. “Welcome to a new era!” Jaan Puusaag said, in summing up the purchase transaction.

NEW! PENOSIL EasySpray is a sprayable insulation foam with a special foam gun nozzle designed by Krimelte. The spray nozzle allows to insulate uneven or hard-to-reach surfaces, where traditional insulation materials cannot be used. Most common application areas are attics, balconies, garages, basements, various containers, etc. Insulating cold surfaces with EasySpray is also a good remedy to avoid condensation.

AIRTIGHTNESS SIMULATOR! PENOSIL offers a wide range of products to help you address problems related to the building energy efficiency. With our airtightness simulator, it will be possible to carry out a differential pressure test during the trade fair, thus detecting leaks in the air and making sure, that the correct use of our construction foam and other sealing materials is very effective.

PENOSIL SPEEDFIX! In 2018 PENOSIL launched new SpeedFix range, where are nine construction adhesives that provide fast initial tack and strong bond. SpeedFix adhesives were developed to meet customers desire for adhesives with greater user convenience.

An energy efficient building is achieved using energy efficient materials

The European Union has set the ambitious aim of reducing human greenhouse-gas emissions by 80-95% by 2050 in comparison to 1990. The EU is slowly moving towards nearly zero-efficiency buildings that in turn create a demand for building materials, as the energy costs of a building make up roughly 40% of total energy usage.

“It is clear that in order to contribute to reducing greenhouse gas emissions, the amount of energy used in a building for heating, cooling, water heating and lighting must be reduced, and renewable energy sources will probably need to be harnessed,”according to Kuldar Kongo, product manager of Krimelte OÜ, in responding to the Energy Performance of Buildings Directive.

All new buildings finished after 31 December 2020 must be nearly zero-energy buildings, according to the aforementioned directive. This requirement for new buildings used and owned by government offices has already been in effect since 2019.

According to Kongo, the energy efficiency of a building depends on the general need for energy, type of supplied energy, on-site production of energy from renewable energy sources, and the amount of heat loss through the outer envelope. “Various methods and solutions must be applied together to meet the requirements of a nearly zero-efficiency building, from the right planning of the buildings’placement and use of renewable energy sources to well thought-out envelopes to minimise heat loss. The construction of nearly zero-efficient buildings in Europe increases expectations and demands regarding the quality of materials and the competence of salespersons.”

The manufacturers of building materials have been focusing on the development of materials for the construction of nearly zero-energy buildings for years. “For example, the product portfolio of our trademark Penosil includes products that solve technical heat and moisture related issues, thereby contributing to better energy efficiency, and these features must also be kept in mind during any further product development. We have developed a complete solution for energy efficient window placement, by which our products help to solve problems and issues related to a window node. In addition to energy efficiency, the development of our products also considers their durability in time and the contribution to a healthy indoor climate.”

Heat loss through envelope

Increasing the thickness of the insulation layer on the outer envelope is sufficient to minimise heat loss. According to Kongo, it should not be forgotten that although heat loss by conduction through envelopes is one of the major factors influencing energy loss, a building will also lose heat in addition to heat conduction through unplanned air leaks and cold bridges. The insulation layer thickness has often reached its limits of cost effectiveness, meaning that no additions will be cost efficient and one should focus on the removal of air leaks and cold bridges.

“The importance of air tightness is illustrated by the fact that proofing subsequent to construction has become unavoidable”, Kongo adds. “The envelopes are accompanied by a large amount of other important requirements: avoidance of technical humidity issues, fulfilment of indoor climate requirements, reduction of noise issues and fire safety.”He adds that one of the major challenges regarding the buildings is correct window placement, because this involves interruption of the external insulation layer along with the airtight and water vapour proof layers.

How can you guarantee a correct and energy efficient window installation?

aknasõlm 2 aknasõlme tekst 2



Reduce heat losses to a minimum. Use materials for window joints with the least amount of heat conduction such as PU-building foam. In addition, the heat conduction losses depend on the depth of joints e.g., they are smaller for windows with wide frames due to the increased depth of a joint.

Provide air tightness to reduce heat loss due to air leaks. The correct application of quality montage foam should by itself be enough to provide air tightness in a joint. To guarantee air tightness during the buildings’operation, the additional use of special tapes, membranes or mastics should be considered.

The warranting of water vapour resistance protects structures against excessive moisture. Depending on the climatic conditions, the water vapour may move from indoors out or from the external environment inside. The first scenario is predominantly present in Nordic countries during most of the year while the second scenario is in mainly warmer areas. Specific air and vapour resistant tapes, membranes and mastics are used to avoid the entrance of water vapour into the envelope. Such a construction must always include a high quality thought-through ventilation solution.

Ensure the escape of moisture trapped within the construction. This includes moisture in construction details during the construction or moisture ending up in the envelope due to poor quality in planning or building. Humidity must not be trapped in the construction - in such cases, tapes with little vapour resistance or self-expanding sealants are used.

Protect inner construction from external weather conditions (UV radiation, precipitation, wind). This presumes that the joint is covered on the outside with a weatherproof sealant or self-expanding sealant. If the joint is insulated from the outside using a highly moisture proof material, the escape of moisture from the construction must be allowed through e.g., façade ventilation.

Avoid cold bridges. This means that the window must always be placed within the insulation layer and the joints created during placement must be filled using montage foam with little heat conduction.

Joints must be able to endure various movements and deformations of the building. Highly flexible sealants are the best for large windows, where it is recommended to use foams with higher elasticity due to linear expansions as a result of temperature and humidity changes, and for outer weatherproof sealing.

Provide sound insulation. During window placement, it is also important to seal cracks and leakage spots because it will help to improve sound insulation in addition to air tightness. Correctly-placed montage foam will mainly fulfil this requirement, but to fill smaller cracks, it is possible to use special sealants for this purpose, e.g., to fill a crevice between the inner window reveal and window jamb using acrylic sealant.

Provide fire resistance. Use only certified products with increased fire resistance and sensitivity for the placement of fire rated windows!
