Dynasylan® MTMO by Evonik acts as an adhesion promoter, crosslinking agent, surface modifier and reactive reagent. It is a bifunctional organosilane with a reactive organic mercaptan and a hydrolyzable inorganic trimethoxysilyl group. It offers improved mechanical & electrical properties, moisture- & corrosion resistance and increased thermal resistivity. It provides adhesion, filler dispersion, rheological behavior (viscosity reduction) and higher filler loading. Dynasylan® MTMO is suitable for glass- and metal primers. It is compatible with polymers such as polyurethanes and polysulfides. It is also used in the pretreatment of fillers & pigments. It has a shelf life of at least 1 year.
