SiSiB® PC3200

3-Glycidoxypropyltriethoxysilane

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.


SiSiB® PC3200 epoxy silane oligomer is the equivalent of Momentive's A-1871, Dow's Z-6041, Wacker's GF82, Evonik's Dynasylan GLYEO, ShinEtsu's KBE-403 silane.

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.


Application

  • SiSiB® PC3200 may improve dry and wet strength in cured composites reinforced with glass fiber rovings.


  • SiSiB® PC3200 epoxy silane 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 silicone coatings.


Packing and Storage


  • SiSiB® PC3200 is supplied in 200Kg steel drum or 1000Kg IBC container.


  • In the unopened original container SiSiB® PC3200 has a shelf life of one year in a dry and cool place.
