Resin ER20 – Hardener EH96

 

ER20 Resin:             1 x 1 kg       Bottle
EH96 Hardener:    1 x  200 g   Bottle

 

Low viscosity, clear, semi-flexible, tough epoxy laminating resin system for room temperature foundry patterns and master moulds.

Also used as a potting resin for electronic components. Minimum Irritation Potential Hardener.

ER20 – EH96 is used with fiberglass tooling fabrics for laminated moulds, with cotton flocks as a coupling coat behind gelcoats, and mixed with sand or other fillers as a casting or ramming concrete to reinforce patterns and negatives.

EH96 gives a higher HDT after post-curing at 100 C.
