Specifications

Application

Silane Coupling Agent Crosile®189 a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group

Improve properties as below:

* Compression set

* Improved mechanical properties

* Improved moisture and corrosion resistance

* Improved electrical properties

* Increased thermal resistant

Excellent protection for metal surface:

3-Mercaptopropyltrimethoxysilane has special effect on the metal surface rust inhibitor.

With its thiol functional group, it can strengthen the surface corrosion resistance and oxidation resistance and increase the adhesion with resin, when face gold, silver and copper surface processing.

Application：

Glass composites: as a finish or a size ingredient

Glass and metal primer

Sealants and adhesives: as a primer, additive, or for chemical modification of the polymer

Mineral filled polymers: for pretreatment of fillers and pigments or as an additive crosslinking of polymers
