Metals are used in many industries, such as the automotive industry, mechanical engineering or the construction industry. Depending on their application, the surfaces are exposed to different external influences and therefore require protection. The most important form of protection is against corrosion, which eats away at the material and jeopardizes reliability while at the same time causing damage that is expensive to repair. With its water-based silanes, Evonik offers environmentally friendly and effective solutions for protecting metallic surfaces. They form a chemical barrier that acts as a durable and robust protective layer for the metal. 

Many things require consideration when formulating a protection system for metals, including the type and quality of the surface or the conditions that it will be exposed to (such as harsh weather or salt water). Evonik’s experts develop suitable formulations for each case together with our customers, thus ensuring that the product’s performance meets all requirements.
