Liquid curative

Ethacure 300 curative, a liquid used for all commercially available prepolymers, is featured in the company's six-page, four-color folder. Ethacure 300 curative is a liquid urethane curative in a low-viscosity form that is said to be easy to mix, meter and dispense. It can be used to produce polymers at temperatures as low as room temperature. Ethacure 300 curative does not solidify in machine process lines if power is lost to heating and circulating equipment. Also, machine clean-out can be performed at room temperature, which is said to make the process faster and safer, according to the literature. Ethacure 300 curative is a liquid with relatively low vapor pressure, so there are said to be no detectable fumes and no dust exposure. (Albemarle, 451 Florida St., Baton Rouge, LA 70801)
