SiSiB® PC3200

Synonym: 3-(2,3-Epoxypropoxypropyl)triethoxysilane;

Countertype of Dynasylan GLYEO, DowCorning Z-6041, ShinEtsu KBE-403, Wacker GENIOSIL GF 82, Silquest A-1871
Chemical Structure

SiSiB® PC3200 is a clear colorless, low-odor liquid. PC3200 may be used as an adhesion promoter (coupling agent) for organic/inorganic interfaces, as a surface modifier (e.g. regulating surface polarity) or as a crosslinking agent (moisture-curing of polymers). When used as coupling agent, it generally reduces the sensitivity of the products' mechanical and electrical properties to heat and/or moisture.

Solubility and Reactivity:

SiSiB® PC3200 is a sparingly miscible with neutral water. In acidified water, hydrolysis to the soluble silanol occurs (PH<4). SiSiB® PC3200 is miscible with practically all organic compounds and enters into the typical reactions of an organic epoxide with, e.g. acids, amines and alcohols. Alkaline or acid catalysts might be advisable for the desired reaction. Polymerization via the epoxide groups cannot be ruled out completely under extreme conditions.
SiSiB® PC3200 may improve dry and wet strength in cured composites reinforced with glass fiber rovings.
SiSiB® PC3200 may enhance wet electrical properties of epoxy-based encapsulate and packaging materials.
SiSiB® PC3200 may eliminate the need for a separate primer in polysulfide and urethane sealants.
SiSiB® PC3200 may improve adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
