Dynasylan MTMO 3-Mercaptopropyltrimethoxysilane 4420-74-0 Degussa-Silanes Adhesion promoter / Bonding agent >> Organofunctional silane Crosslinking / Coupling / Curing Agents Polyurethane Metal >> Primer Other industry >> Glass Coating Soluble in alcohols Soluble in aliphatic hydrocarbons Soluble in ketones Soluble in aromatic hydrocarbons DYNASYLAN MTMO is a bifunctional organosilane possessing a reactive organic mercaptan and a hydrolyzable inorganic trimethoxysilyl group. The dual nature of its reactivity allows DYNASYLAN MTMO to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent, surface modifier or reactive reagent. DYNASYLAN MTMO is a clear, colorless to light yellow liquid with a ester-like to mercaptan odor. Used as glass and metal primer improved product properties, such as adhesion improved mechanical properties, for example flexural strength, tensile strength, impact strength and modulus of elasticity improved moisture and corrosion resistance improved electrical properties, for example dielectric constant, volume resistivity improved processing properties, such as better filler dispersion rheological behavior: reduction in viscosity,Newtonian behaviour higher degree of filling Bifunctional organosilane possessing a reactive organic mercaptan and a hydrolyzable inorganic trimethoxysilyl group. Used as glass and metal primer. Acts as and adhesion promoter, crosslinking agent, surface modifier or reactive reagent. Improves mechanical and electrical properties, moisture and corrosion resistance. Increases thermal resistivity. Provides better filler dispersion and rheological behavior.
