Tetramethoxysilane : Guide

Tetrapropoxysilane is commonly used as a lubricant, mold release agent and anti-sticking agent. Because of its good lubricity and surface tension-reducing properties, it can be used to make lubricants, polishes, anti-stick agents, and additives for plastic and rubber products.

– It can also be used to make silane-modified polymers, resins and coatings to improve wear, chemical and water resistance.

– Tetrapropoxysilane can also be used in the electronics industry for the lubrication and insulation protection of chips and displays.
