99% 3-Aminopropyltriethoxysilane CAS 919-30-2 KH550

Certificate of Analysis-COA 

 Applications 

1.Coupling Agent For Inorganic And Organic Systems: 3-Aminopropyltriethoxysilane (CAS 919-30-2) is an amino silane coupling agent that bonds inorganic materials such as glass, metals and mineral fillers to organic polymers.

2.Glass Fibre And Composite Treatment: Used as a glass fibre treatment agent and composite additive, it improves the compatibility between inorganic fillers and the polymer matrix in composite formulations.

3.Adhesion Promoter For Coatings And Adhesives: It works as an adhesion promoter that bonds epoxy, polyurethane and acrylic coatings and adhesives to glass and metal substrates.

4.Construction And Cement Systems: In construction applications it forms a covalent bridge between cement surfaces and epoxy systems, helping that bond hold up when moisture is present.

5.Surface Modification And Silanisation: The silane is used to modify silica and metal oxide surfaces and to attach organic films covalently, a route also used to prepare adsorbents for affinity chromatography.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
