Description

ETHACURE 420 curative is an effective curing agent for polyurethanes. It can be used as a chain extender for polyurethane and polyurea elastomers, rigid and flexible foams, adhesives and joint sealants as well as in spray applications.

Often used in combination with ETHACURE 100 to adjust curing rates in fast reacting systems, ETHACURE 420 boosts polymer performance, particularly elasticity, surface finish, adherence capabilities, and pot life. ETHACURE 420 makes it easy to produce the soft elastomers needed for caulks and sealants.
