ETHACURE 300 is a liquid aromatic diamine curative with low chronic toxicity, making it an effective curing agent for polyurethane and polyurea materials in the advanced materials industry. As a curative, ETHACURE 300 provides benefits such as being suitable for both hot and room-temperature casting applications. It can also be used as a slower chain extender for elastomers used in reaction injection molding and other advanced material fabrication processes. ETHACURE 300 offers properties like high reactivity and solubility that allow for uniform curing of advanced composite materials. Its low vapor pressure also helps reduce emissions during high-temperature processing of advanced materials.
