Hiposil is system of silyl modified polymers ( also known as SMP/MSP/STP/MS POLYMER). Based on multifunction-terminated groups and special crosslinked functional groups involved, Hiposil has excellent comprehensive properties combining the advantages of silicone and polyurethane polymers. It is usually used as a reactive binder for moisture-curing elastic sealants and adhesives.

Hiposil X146 is silane terminated polyether with lower viscosity prior to curing. It is used as the main raw material in industrial adhesives, sealants and coatings for its isocyanate-free, solvent-free and odorless traits, no bubbles during curing. Adhesives and sealants based on Hiposil X146 have excellent  moisture-curing  capacity.
