The lightweight construction industry heavily relies on composites, which consist of organic and inorganic materials. During the manufacturing of lightweight materials, silanes like DYNASYLAN® are used for surface modification. This ensures that the organic and inorganic components adhere well to each other, forming durable bonds and interactions. Additionally, silanes facilitate the transfer of mechanical energy from the organic network into the fibers.
Coating systems and finishes must perform a wide range of functions, from temperature, UV and weather resistance to mechanical and chemical resistance and corrosion protection. At the same time, there is a growing demand for sustainable solutions and ease of application. Silanes play an important role in meeting these requirements. Through targeted surface modification, materials can be made hydrophobic, oleophobic, hydrophilic or oleophilic. The silanes bond to the substrate with their functional silicon group, while the organofunctional side achieves the desired effect.
Durable concrete and natural stone surfaces
PROTECTOSIL®, our specialized product line for porous surfaces, provides excellent protection for concrete and natural stone. On smooth surfaces such as glass or ceramics, PROTECTOSIL® products provide permanent non-stick protection and easy-to-clean properties, significantly improving the service life of materials and extending their maintenance cycles.
Lasting protection for wood and textiles
Silanes from our DYNASYLAN® range are suitable for cellulosic materials such as wood or textiles. Used as an additive in the overall formulation, they prevent water, oil or grease from penetrating the treated surface. This not only extends the service life of an object but also provides long-term protection against dirt carried by liquids.
Evonik’s silane-based solutions offer customized surface modifications for almost any application, meeting the highest standards of functionality and sustainability. Silanes are also a promising alternative in the context of the PFAS avoidance (per- and polyfluoroalkyl substances) megatrend in Europe: Evonik is working intensively on the development of formulations in which silanes can partially replace corridor products, unlocking significant potential for future environmentally friendly solutions.
Silane-based Evonik products provide facades with long-lasting protection
The facades of buildings and structures such as bridges or multi-storey car parks are often exposed to two different types of pollution. On the one hand, dust, dirt and vegetation such as algae or moss. On the other hand, graffiti. To counter both, it is advisable to treat the surface of the substrate with PROTECTOSIL®. The silane-based product from Evonik provides reliable graffiti protection and an “easy-to-clean” effect. Dirt, growth and graffiti paints do not stick to the facade and can be easily removed.
