3-(Dimethoxymethylsilyl)propylamine: Guide

3-(Dimethoxymethylsilyl)propylamine is also known as 3-Aminopropylmethyldimethoxysilane. it is an aminosilane coupling agent containing amino functional groups. It is mainly used to enhance the adhesion to inorganic materials such as metal, glass and filler.
It can be used as an adhesion promoter in the paint, coating, adhesive and sealant industries. It is usually used in one-component and two-component polysulfide sealants. It can be used to improve the bonding properties between organic resins and inorganic materials. It enhances adhesion to inorganic materials such as metals, glass, and ceramics. Can be used as an additive for special primers in many bonding applications. Often used as a surface modifier for inorganic fillers and pigments. Also used in the synthesis of textile and fabric additives.
