AcylSilane / Acyloxy Silanes

3-Aminopropyltrimethoxysilane (CAS No. 13822-56-5), is a colorless to light yellow multifunctional amino-functional coupling agent. It is a functional silane with amines and hydrolyzable methoxy groups that provide excellent adhesion between inorganic substrates and organic polymers. The primary amine functional group reacts with a wide range of thermoset, thermoplastic and elastomeric materials.

3-Acryloxypropyltrimethoxy silane: Guide

3-Aminopropyltrimethoxysilane is a kind of organosilane with active amine group and hydrolyzable inorganic methoxymethoxysilane bifunctional group, it is a colorless liquid with special ammonia odor, it is soluble in solvents such as alcohols, chain hydrocarbons and aromatic hydrocarbons, etc. It is produced by the addition of chloropropylene and trichlorhydrosilane.
Chloropropyltrichlorosilane is obtained by the addition of chloropropene and trichlorohydrosilane, then reacted with methanol, and the product is obtained by ammoniation and separation.

CAS 13822-56-5 Silane can be used as a surface modifier for inorganic fillers and glass fibers to improve the bonding properties of organic resins and inorganic substrates.
Can be used as a primer or additive in the coatings and sealants industry.
Can be used as an adhesion promoter in silane-modified polyurethanes (called SPUR polymers).
Can be used as surface protectants and adhesion promoters to prepare silanized surface treatments for metals.
