PC-730HAR is a fast set, rapid curing, 100% solids, flexible, two-component abrasion resistant polyurea elastomer spray coating material. PC-730HAR may be used by itself or in combination with other materials to produce coatings, liners, wearing courses, resilient surfaces on metal and other substrates. Its extremely fast gel time makes it suitable for applications down to -40°F without special conditioning of the component resins and isocyanates. PC-730HAR produces an extremely tough film at varying thicknesses using a multiple pass technique. PC-730HAR may be applied in all positions and to any properly prepared, sound substrate. PC-730HAR is inert, it will not hydrolyze, leach, or contaminate other materials, and is bondable and paintable. PC-730HAR is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions.
