Pure Polyurea Coatings

Item No.: PS500A-Pure
This pure polyurea system is a very fast-set, 2-component, 100% solids, No VOCs, flexible coating. Spray-applied elastomers provide significant protection to various metal/steel, wood, concrete, urethane foam, and many other substrates.
Description
Pure Polyurea Coating PS500A is a 100% solid, fast curing, two component, and aromatic,100% Pure polyurea coating system derived from a reaction of an isocyanate prepolymer, MDI, a chain extender, and a pigment, which has the advantages of high strength, good performance and quick construction.Based on the high reactivity and fast curing property, it can be sprayed forming at any bent, inclined and vertical surface without sagging. With super adhesive strength and impact-resistant characteristics, the coating is flexible, impact-resistant, and seamless and is able to completely insulate air, water, and oxygen penetration. It integrated anticorrosion, waterproof, wear resistance, aging resistant performances, no pulverization and crack peel up or fall down after long- term outdoor work with alternating ambient conditions of cold, heat, rain and snow. It is the optimum choice where a tough, flexible, impact resistant, abrasion resistant waterproofing system which exhibits extraordinary performance characteristics.
