Welcome to Advanced Polyurea & Polyaspartic Coatings

Seawater Desalination Caisson Special Coating

Item No.: HS800C
polyurea systems are resistant to seawater and saline fog, have an excellent adherence over metal and concrete and do not allow for the development or anchoring ofmicroorganisms or plants, making them the ideal interior and exterior coating of pipes, filters and deposits in desalination plants.
HS800C Seawater Desalination Caisson Special Coating is a 100% solids, two-component, fast-set, high-performance on-site spray molding materials. The product is mainly composed of isocyanate semi-prepolymer, terminal amino polyether chain extender and 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 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.
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.
