Silyl modified polymers

Silyl-modified polymers (SMP; also "silane-modified polymers", "modified-silane polymers", "MS polymers", "silane-terminated polymers", etc.) are polymers terminating with a silyl group. SMPs are the main components in solvent-free and isocyanate-free sealant and adhesive products. Typically the sealant products manufactured with silyl-modified polymers have good adhesion on a wide range of substrate materials, and have good temperature and UV resistance.
Curing process.
The products cure from a liquid or gel state to a solid. Curing entails crosslinking by the hydrolysis of silyl ethers:
This hydrolysis generates siloxane linkages. A catalyst is required for this condensation process.
