3-Aminopropyltrimethoxysilane Usage And Synthesis

Uses

3-(Trimethoxysilyl)-1-propanamine is an amino-functional silane that may be used over a broad range of applications to give an improvement in the bond between a substrate, filler or reinforcement and resins that react with the amino group.
3-(Trimethoxysilyl)-1-propanamine is especially recommended to thermoplastic resins and thermosetting resins such as epoxy, PBT, polyurethane etc. It can improve reinforced plastic's physical properties and electric properties as flexural strength, compression strength and shear strength. It also can improve the dispersion and wet ability of filler in the high molecular materials. 3-(TRIMETHOXYSILYL)-1-PROPANAMINE is an excellent promoter of adhesion and sealant (such as polyurethane, epoxy, and phenol). In the glass wool and FRP products, it can be added into phenol resins to improve the wet resistance and mechanical performance. Applications:

• Superior adhesion promoter in RTV silicones and other hybrid sealants.
• Excellent adhesion promoter for difficult substrates such as ABC, PVC ad Poly Shyrene.
• Useful component in primer systems for hybrid and polyurethane sealants.

Chemical Properties

Colorless transparent liquid

Uses

(3-Aminopropyl)trimethoxysilane is used as a silane coupling agent on silver nanoparticles. It is also used in silanization processes. It is also used to prepare surface modified titanate nanotubes (TiNT).

General Description

(3-Aminopropyl)trimethoxysilane(APTMS) is an amino-silane that is mainly used as a silane coupling agent for the surface modification of a variety of nanomaterials. APTMS based films form a thermally stable layer on different substrates.
