Silyl modified polymers (SMP, also silane-modified polymers, silane-terminated polymers) are polymers (large, chained molecules) terminating with a silyl (SiH3) group. SMPs are the main components in solvent-free & 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 & UV resistance.
