Tetramethoxysilane : Guide
Tetrapropoxysilane is a highly effective lubricant, mold release agent, and anti-sticking agent, thanks to its excellent lubricity and surface tension-reducing properties. It is commonly used to formulate lubricants, polishes, anti-stick agents, and additives for plastic and rubber products.
In addition, Tetrapropoxysilane is ideal for creating silane-modified polymers, resins, and coatings that enhance wear resistance, chemical resistance, and water resistance. Its versatility extends to the electronics industry, where it is used for chip lubrication and insulation protection, as well as display coating, making it a vital compound in both industrial and electronic applications.
