PC-720 is a fast set, rapid curing, 100% solids, flexible, two-component polyurea elastomer spray coating material with enhanced color stability capabilities. PC- 720 is used by itself or in combination with other materials to produce coatings, liners, wearing courses, and resilient surfaces on metal and concrete substrates. PC-720 produces an extremely tough film at all thicknesses. Single or multiple pass applications produce films from 10 mils up to 1000 mils without appreciable sag or runs. PC-720 may be applied in all positions and to any suitably prepared substrate. PC- 720 is inert, it will not hydrolyze, leach, or contaminate other materials, and is bondable and paintable. PC-720 is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions.
