D.E.N.™ 425

Approximately 2.5 functional liquid epoxy novolac resin bridging between standard liquid epoxy resin and semi-solid epoxy novolac resins. When used in combination with a fast curing agent no post-cure is required and binder systems are obtained with excellent mechanical and especially solvent resistance properties.

EMEAI, NAA
D.E.N.™ 431

Multi-functional (±2.8) epoxy novolac resin of lower molecular weight for application where solvents cannot be tolerated and application viscosity (temperature) needs to remain relatively low. Used in adhesives, electrical and structural laminates and castings for elevated temperature service and excellent chemical resistance.
