  5.Key Features And Benefits
  Feature Benefit
  Epoxy Epoxy ring is reactive with mary organic functionalities
  Functionality Epoxy functionality will offer non-yellowing adhesion in many resin systems
  Trimethoxy Silane Bonds to inorganic substrates to provide excellent wet and dry
  Adhesion
  Functionality Very fast hydrolysis rate
  1. Enhanced electrical properties of epoxy electronic encapsulant and packaging
  Materials,resulting from inprowved bonding between resin and substrate or filler.
  2. Usefulin waterborne applications such as acrylic and vinyl-acrylic caulks.
  3.Improvedadhesion to glass,and metal substrates can be obtained in epoxy,polysulfide,urethane and acrylic bases, adhesives,sealants and caulks.
  4.Epoxy applications benefiting from the use of it include quartz filled epoxyencapsulants,pre-mix formulations for mold die tools.Epoxy encapsulation systems benefit from epoxy family of silanes ability to enhance wet adhesion,reducing the risk of semiconductor or integrated circuit failure due to water ingress or suface corrosion.typical use levelis 1.0 pbw.
  5. Urethane applications benefit from enhanced adhesion performance,without suffering odor issues associated with mercapto based silanes. Typical use level ranges from 0.5to1.5pbw.
  6. 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 from0.2to0.5pbw.
