Silane Terminated Polyether

SiSiB® STP71280 is a dimethoxysilane and triethoxysilane mixed-terminated polyether polymer. It could be applied in moisture curing elastic sealant, elastic structure sealant and sealing coatings. Sealants based on SiSiB® STP71280 not only have excellent adhesion properties, but also have adhesion to broad range of substrates. 


Different from polyurethane and silicone system, this formulation have no solvent and isocyanate, as well as no bubbles and odour generated from curing. It is especially suitable for silicone construction industry, transportation industry and general industry application..
