Composites made from synthetic resins are used in many application fields, such as molds, sanitation ceramics and mechanical engineering. To ensure their durability, they must meet various requirements, including the end product’s resistance to mechanical stresses, its thermal stability and UV resistance. When formulating high-fill composites, good processability of the ingredients is crucial to achieving the desired stability and strength. This is made possible by using organofunctional silanes in various functions, for example as adhesion promoters. 

In modern composites, organofunctional silanes from the Dynasylan® series ensure that the desired strength is achieved. Although they make up just 0.1 to 1.0 percent of the material, they have a monumental effect. Silanes form strong chemical bonds between the organic binding agent and the inorganic filler system, ensuring that the final product has a long lifespan.
