Description

General description

(3-Glycidyloxypropyl)trimethoxysilane (GPTMS) is a bifunctional organosilane with three methoxy groups on one side and an epoxy ring on the other. The methoxy groups bind well with glass substrates creating a 3D matrix. The epoxy group is reactive with amides, alcohols, thiols and acids. GPTMS is highly reactive in water and can be used as a linking agent between the surface of the silica and the polymeric matrix.

Application

GPTMS is widely used as a silica precursor. GPTMS alone with tetraethylortosilicate (TEOS) can be blended with chitosan for use as a filler for polymeric scaffold for bone tissue engineering. It can also be coated on the surface of aluminium alloy to protect from corrosion. GPTMS can used to functionalize (wrap) multi-walled carbon nanotubes (MWCNTs) which can be used as s a reinforcement in epoxy matrix nanocomposites.

Pre-treatment of carbon steel with 3-(Glycidoxypropyl)trimethoxysilane enhances the dry and wet adhesion while reducing the cathotic disbondment rate of an epoxy coating
