The TCVN 9012-2011 standard specifies the technical requirements, performance indicators, test methods and usage specifications of zinc-rich Coatings. Zinc-rich Coatings are widely used for the protection of metal structure surfaces due to their excellent anti-corrosion performance, especially in marine, industrial and other high-corrosion environments. The standard content includes the composition of Coatings, zinc powder content, adhesion, corrosion resistance, drying time and construction technology requirements, and at the same time clarifies the mass inspection and detection methods. The standard provides a scientific basis for the production, selection and application of zinc-rich Coatings, which helps to improve the service life of metal facilities, reduce maintenance costs, and provide technical support for anti-corrosion projects in related industries.
