Welcome to Advanced Polyurea & Polyaspartic Coatings

Coastal Dam Polyurea Protective Coating

Item No.: PS700B
Coastal Dam is located in severely corrosive place,it endures the erosion of the sea wave,burning sunlight and marine organism,tends to be ruined.Polyurea spray elastomer coating is an ideal protective material with good physical properties and anti-corrosive.
PS700B is a pure polyurea coating designed specifically for coastal dam.100% solids, two-component, fast-set, high-performance on-site spray molding materials.  B compone is an isocyanate prepolymer, the A component is an MDI, a chain extender and a pigment of fire retardant, 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 resistance characteristics, the coating is flexible, impact resistant and seamless that able to completely insulate air and 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.
Anti-corrosion and waterproof protection of coastal and dyke dams and other facilities.
1>. Without any thinner, environmental protection;
2>. Elongation, high flexibility, can adapt to the basic cracks and slight deformation;
3>. Good aging resistance
4>. fast-set, can be sprayed on any surface, slope, vertical surface;
5>. Convenient construction, spraying a film.
