Silyl modified polymers


Silyl modified polymers 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.
