DMTDA Equivalent To Ethancure 300 Chain Extender For Polyurethane Cast Elastomers

DMTDA curative is a liquid aromatic diamine with low chronic toxicity, serving as an effective curative for polyurethane cast elastomers. It is suitable for both hot and room-temperature casting applications. Additional uses include functioning as a slower chain extender for polyurethane urea and polyurea elastomers in reaction injection molding, structural reaction injection molding, and hand-applied or spray coating applications, either alone or in blends with DETDA curative.
