Model No: PH9512
Description:
Gas &oil pipelines usually go through the complex geological structure and changeable climate zones. The geological structure changes caused by different climate, soil corrosion as well as the displacement and deformation will greatly damage the buried pipelines. PH9512 pipeline special spray is a 100% solids, two-component, fast curing, high-performance on-site spray molding materials. The A component is an isocyanate prepolymer, the B component is an amino terminated polyether, a polyether polyol, 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 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 snowhas excellent comprehensive physical performance and stable anticorrosion properties which have gained attention from the designers and applicators and been increasingly used in projects of buried pipelines.
Characteristics:
It is high reactive, rapid curing, able to spray forming on any bending slope and vertical surface without sagging. The coating membrane is dense and flexible, insensitive to moisture and temperature, high adhesion to substrate and cathodic disbondment resistant. It has excellent properties of impact and wear resistance, stable chemical resistance to acid, alkali and salt, well protection from erosion of microorganism and plant roots, no cracking and peeling after long-term application.
