Silane coupling Agent KH-172

Product: Silane coupling Agent KH-172

Chemical Name: Vinyltris(2-methoxyethoxy)silane

CAS No.:   1067-53-4       

Structure formula:

Introduction: 

 KH-172 is a vinyl-functional coupling agent that promotes adhesion among unsaturated, polyester-type resins or crosslinked polyethylene resins or elastomers and inorganic substrates, including fiber glass, silica, silicates and many metal oxides. When used as coupling agent, it reduces the sensitivity of the products mechanical and electrical properties to heat and/or moisture.
