Key Features and Benefits

Epoxy Functionality

• Epoxy ring is reactive with many organic functionalities.
• Epoxy functionality will offer non-yellowing adhesion in many resin systems.
• May improve flexibility of systems vs. other adhesion promoters.

Trimethoxy Silane Functionality

• Bonds to inorganic substrates to provide excellent wet and dry adhesion.
• Very fast hydrolysis rate.

• Enhanced electrical properties of epoxy based electronic encapsulant and packaging materials, resulting from improved bonding between resin and substrate or filler.
• An excellent candidate for waterborne applications such as acrylic and vinyl-acrylic caulks.
• Improved adhesion to glass, and metal substrates can be obtained in epoxy, polysulfide, urethane and acrylic bases adhesives, sealants and caulks.
  • SPUR+ perpolymer applications benefit from adhesion without decrease in elongation and yellowing.
  • Urethane applications benefit from enhanced adhesion to glass and metal substrates, while providing improved shelf stability over amino silane alternatives. Typical use level ranges from 0.5 to 1.5 pbw.
  • Epoxy applications benefiting from the use of Silquest A-186 silane or Silquest A-187 silane include quartz filled epoxy encapsulants, pre-mix formulations, sand-filled epoxy concrete patching materials, and metal filled epoxy materials suitable for mold die tools. Epoxy encapsulation systems benefit from Momentive Performance Materials epoxy family of Silquest silanes’ ability to enhance wet adhesion, reducing the risk of semiconductor or integrated circuit failure due to water ingress or surface corrosion. Typical use level is 1.0 pbw.
  • Polysulfide applications benefit from enhanced adhesion performance, without suffering odor issues associated with mercapto based silanes. Typical use level ranges from 0.5 to 1.5 pbw.
  • Latex caulk applications benefit from enhanced adhesion to glass and metal substrates, without suffering yellowing issues associated with amino silane adhesion promoters. Typical use level ranges from 0.2 to 0.5 pbw.
