Product Feature
Amine-HCA ™ C3-LF, as a delayed reaction type polyurethane chain extender,which is formed by complexing a symmetrical aromatic diamine with sodium chloride. At room temperature, it has little activity, but when heated to a certain temperature, the salt complex begins to unseal, and the free diamine reacts quickly with the prepolymer to form an elastomer. Because Amine-HCA ™ C3-LF is a liquid with suitable viscosity, it can be mixed with the prepolymer at room temperature without melting, and is suitable for molding processing technologies such as atmospheric pouring, pressure or injection molding, rotary pouring and immersion in a reaction kettle. Especially suitable for large area construction, precision pouring, complex structure casting preparation, microwave vulcanization and other processing forms that need not be limited by life and stability in the kettle. It has similar vulcanization property to MOCA, and does not appear gelation when mixed with prepolymer without heating. At the same time, the product also can be used as a curing agent of one-component polyurethane adhesive and the produced one-component polyurethane adhesive has excellent performance.
Product advantages
☆ Liquid at room temperature, no melt, easy to operate.；
☆ When mixed with the prepolymer, it has enough time to operate；
☆ The prepared polyurethane products have high rebound, high wear resistance and excellent dynamic properties.
