PC-705PW is a fast set, rapid curing, 100% solids, flexible, two-component pure polyurea elastomer spray coating material for POTABLE WATER applications. PC-705PW is used by itself or in combination with other materials to produce coatings, liners, wearing courses, and resilient surfaces on concrete and other substrates. Its extremely fast gel time makes it suitable for applications down to -30°C without special conditioning of the component resins and isocyanates. PC-705PW produces an extremely tough film at all thicknesses. Single or multiple pass applications produce films from approx. 0.5 mm to 25 mm without appreciable sag or runs. PC-705PW may be applied in all positions and to any suitably prepared substrate. PC-705PW is inert, it will not hydrolyze, leach, or contaminate other materials and is bondable and paintable. PC-705PW is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions.
