3-Isocyanatopropyltriethoxysilane is suitable for polyacid resin, epoxy resin, phenolic resin, melamine formaldehyde resin, nylon, polysulfone and other FRP materials. FRP treated by 3-Isocyanatopropyltriethoxysilane can be widely used in the manufacture of mechanical parts, building materials, pressure vessels and reinforcement materials for some special purposes. 3-Isocyanatopropyltriethoxysilane can react with active hydrogen in organic polymers easily. CFS-885 with high functionality can be used as the equivalent of Momentive Silquest A-Link 25 or ShinEtsu KBM-9007.
