Silquest™ A-1871

It is a gamma-Glycidoxypropyltriethoxysilane. Acts as adhesion promoter. This epoxy functional silane provides outstanding chemical resistance, mechanical properties, improved adhesion to glass and metal substrates. It also provides crosslinking of waterborne latexes and dispersions; acrylic, styrene acrylic or other copolymers, polyurethane or epoxy dispersions. Has enhanced electrical properties of epoxy based electronic encapsulants and packaging materials, resulting from improved bonding between resin, substrate or filler. Improved wet adhesion reduces the risk of semiconductor or integrated circuit failure as a result of water ingress or surface corrosion. It also has improved dry adhesion and tensile strength. Use of epoxy silane may avoid the yellowing sometimes seen when amino functional adhesion promoters are used and it also has improved shelf stability over aminosilane alternatives. It is used in caulking applications.
