Our organo-functional silanes can treat almost any mineral or organic substrate to make them water-repellent.
RS-1130
RS-1130 (methyltrimethoxysilane, CAS: 1185-55-3) is a low molecular weight alkylsilane that reacts with a variety of substrates to make them hydrophobic.
RS-6341 (n-octyltriethoxysilane, CAS: 2943-75-1) is a long chain alkylsilane with relatively low reactivity and is primarily used to render substrates highly hydrophobic. The low molecular weight of RS-6341 allows deep penetration into porous mineral substrates.
