DYNASLYAN HMDS is a versatile silylating agent that provides protection and stabilization to various materials. It acts as an efficient silylating agent for derivatization and blocking of functional groups. DYNASYLAN HMDS derivatives exhibit improved chemical stability and enable chemical reactions that otherwise would not be possible. It can silylate inorganic substrates like silica for better dispersion and viscosity reduction. The silylated materials have applications in industries where hydrophobicity, adhesion and chemical stability are important. DYNASYLAN HMDS treatment of fillers improves their dispersion and adhesion in polymer matrices. It also enhances the hydrophobicity of substrates for applications involving durability against moisture.
