  steel structure anticorrosion protective coating

Descriptions               Industry plant shop steel structure mainly influenced by the atmospheric corrosive environment, SO2, H2S, HCl, Cl2, NH3, NaCl and other atmosphere substances all have very large anticorrosion damages. In addition, the floating material in air, such as sand, charcoal and other particulate matter will also scour wear steel structure. Based on the above reason SWD Urethane Co., USA developed industry steel structure anticorrosion protective coating, this product will rise the anticorrosion maintenance cycle of industry plant steel structure to above 10 years.

Characteristics              The Coating has high performances of acid resistance, alkali resistance, ammonia resistance and salt spray resistance. Surface of film is dense, flexible, with high performances of wear resistance, impact resistance and anti-aging. No crack, no peel off, no fall down, the coating can bear alternating impact of hot and cold in various natural environment and erosion scour of the chemical atmospheric ambition. One component product, just open it for use, avoided the cumbersome on-site equipment of two components coating and the quality problems raised from improper proportion preparation. Coating has good construction performance it can be painted on the hand brushable anticorrosion metal surface and cured under condition of low temperature and high humidity.
