PC-842AL is a-100% solids, flexible, two component modified aliphatic elastomer spray applied coating material. PC-842AL is autocatalytic, containing no solvents, hardeners, or diluents. PC-842AL is used by itself or in combination with other materials to produce coatings and liners on concrete or metal substrates. Its composition makes it suitable for applications requiring color stability. PC-842AL produces an extremely tough film at any thickness. PC-842AL may be applied in all positions to any suitably prepared substrate.
PC-842AL is a superior coating material designed specifically for industrial and commercial applications receiving constant or intermittent exposure to ultraviolet light. PC-842AL is flexible, accommodating movement of the substrate, yet strong enough to remain intact under all conditions except major structural dislocations. With or without reinforcements PC-842AL may be used in transitional areas with confidence. PC-842AL may be used in interior or exterior applications.
