Abstract

SCA-E87M is an epoxy functional silane suitable for use as adhesion promoters in polysulfide, urethane, epoxy and acrylic caulks sealants and adhesives.

 

Applications and Performance

1. Enhances electrical properties of epoxy electronic encapsulant and packaging materials, resulting from improved bonding between resin and substrate filler.
2. Stable in waterborne applications such as acrylic and vinyl acrylic caulks and emulsion adhesive and coating.
3. Improved adhesion to glass, concrete and metal substrate can be obtained in epoxy, polysulfide, urethane and acrylic bases adhesive, sealants and caulks.
4. Improves mechanic strength of glass fiber reinforcement or minerals filled engineering plastic especially PA. 

 

Packing

The regular packing of this product is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
