PC-750 is a rapid setting, 100% solids, flexible, aromatic two-component pure Polyurea. This odorless volatile- free elastomeric is specially designed to be applied to concrete, metal, styrofoam (EPS), spray foam and tank lining membranes. PC-750 gels in 8 seconds—it can be applied in single or multiple applications from 10 mils to 1,000 mils without the concern of sagging or running. PC-750 offers a tack-free time of about 15 seconds and will not hydrolyze or contaminate other materials due to its inert nature. PC-750 is moisture and temperature insensitive and will accommodate substrate movements while remaining strong.
