The DB 44/T 1106-2012 standard specifies the technical requirements and test methods for water-based polyurethane anti-corrosion coatings (two-component). The Coating is mainly used for anti-corrosion protection of metal surfaces. It has excellent weathering resistance, water resistance and chemical corrosion resistance. It is suitable for protection needs in various harsh environments. The standard describes in detail the composition, performance indicators, construction process and supporting test methods of the Coating to ensure the mass and effect of the Coating during use. The two-component system requires that the base Coating is mixed with the curing agent before use to ensure that the coating has stronger adhesion and durability. The standard provides a technical basis for the production, application and quality control of water-based polyurethane anti-corrosion coatings, which helps to improve the service life of metal materials and reduce maintenance costs.
