Polyclad 777 PL Fast-Set is a high performance 100% solids structural polyurethane designed to provide superior corrosion protection for steel, ductile iron and concrete pipe. Typical uses include pipeline exterior surfaces. Tenacious adhesion and high impact resistance allow its use in the harshest environments. It forms a dense, long-term impermeable barrier that is ready for service moments after application through a fast-set cure mechanism. No primer is required.
