SILANE A-187

SILANE A-187

2530-83-8

Chemical Name:   3-Glycidoxypropyltrimethoxy silane
Chemical Structure:   CH2CHCH2OCH2CH2CH2Si(OCH3)3
\   /
 O
Molecular Formula:  C9H20O5Si
Characteristic and Usage:   Silane A-187 is a new type of bifunctional coupling agent with epoxy group and trimethoxysilyl group, can be easily hydrolyzed and crosslink. The dual nature allows K-56 bind chemically both inorganic materials (glass, sand, fillers) and organic polymers (thermosets, thermoplastics)
1. Glass fiber/glass fabric: as a finish or size ingredient
2. Foundry resin: as an additive to polyurethane resins 
3. Mineral filled composites: for pretreatment of fillers and primer for improving adhesion to the polymer
4. Paints and coatings: as an additive and as a primer for improving adhesion to the substrate, especially glass and metal.

Packing and Storage

1. Silane A-187 should be hermetically stored, because of its reactivity, it will be hydrolyzed by moisture to form polymer.
2. Silane A-187 is supplied in 10kg, 20kg, 200kg (net weight) internally new iron drum.
3. Silane A-187 can little stimulate skin and eyes, so labor protection is necessary when contacting.
