China's first water-based anti-corrosion coating standard was introduced

Recently, Guangdong Province formally approved the release of "waterborne polyurethane anti-corrosion coating (two-component) standard", the standard will be implemented from March 31st, which is China's first water-based anti-corrosion coating standards. The promulgation and implementation of the new standard will promote the construction of a water-based product standard system for the paint industry in the province, which will help guide the development of the water-based anti-corrosion coating industry, will drive the production of heavy anti-corrosion materials in the direction of green protection, and improve the automation level of the coating process. The company's ability to independently innovate and promote products such as marine coatings to reach the level of similar foreign products as soon as possible.

“Water-based” development direction Lv Shuilei, deputy secretary-general of the Guangdong Provincial Coatings Industry Association, said that there are currently dozens of varieties of anti-corrosion coatings, including resins, modified resins, powders, solvent-free, and UV-curable products. Glass flake and so on. However, in China, the overall level of development of the paint industry is low, especially the development of ship heavy anti-corrosion coatings is still in its infancy. Although there are nearly 1,000 companies specializing in anti-corrosion coatings production, the scale is not large, and there are few high-end products and the oversupply of low-end products. .

With the increasing demand of the market for environmental performance of products, in the area of ​​marine coatings, many excellent anticorrosive coatings have emerged in recent years, and gradually developed toward the direction of green environmental protection. Among them, epoxy and polyurethane coatings are in the field of industrial corrosion protection. The application technology is relatively mature and widely used in the shipbuilding industry. Water-borne polyurethane anti-corrosion coatings have been used more and more for their non-flammable, non-toxic, non-polluting, energy-saving, storage-friendly, and high-hardness and wear-resistant characteristics. In response to this trend, Lv Shuilie reminded the domestic anti-corrosion coating companies that the development of water-based anti-corrosion coatings should be used as an important way to “turn green”, such as vigorously developing high-performance anti-rust coatings, super weather-resistant coatings, and anti-corrosion effects for more than 15 years. Ship heavy-duty coatings, high-temperature coatings with special functions, thermal insulation coatings, anti-static coatings, low-energy various types of aliphatic polyurethane coatings and epoxy resin coatings. At the same time, due to the complex construction environment of heavy anti-corrosion coatings, relevant companies must also pay attention to the environmental adaptability of the products during R&D, and must strive to prevent them from being limited by the structure and shape of the equipment, and have the advantages of easy repair and other anti-corrosion measures. With the characteristics.

Urgently, the "standard" guides the release of "Waterborne Polyurethane Anti-corrosion Coatings (two-component) Standard" in Guangdong Province, and China has not yet promulgated standards for water-based anti-corrosion coating products. In accordance with the provisions of the Industrial Product Standards Management Approach, standards implemented by industrial products without specific standards shall be referenced and implemented in compliance with relevant standards for the integrated product system. However, because the product standard system of anti-corrosion coating (solvent type) fails to reflect some major indicators of water-based anti-corrosion coating products, the quality of water-based anti-corrosion coating products cannot be ensured, resulting in the absence of a set of applicable quality indicators in this area, resulting in various manufacturers. The uneven quality of products produced has also hindered the development of this industry. Therefore, it is imperative to perfect the standards for waterborne products in the paint industry and develop a set of standards specifically for waterborne anticorrosive coatings.

The “Waterborne Polyurethane Anticorrosion Coatings (Two-component) Standard” promulgated by Guangdong Province provides detailed stipulations on the classification, test methods, inspection rules, markings, packaging and storage of waterborne polyurethane anticorrosion coatings (two-component). With strong guidance and practicality, a clear product index system has been established for the production and application of water-based anti-corrosion coatings, which has enabled technical indicators and references for engineering design in the anti-corrosion field. The implementation of this standard will help promote the adoption of advanced production technology and improve the technological level. Industry experts pointed out that this standard is only a local standard and hopes that national standards will be introduced as soon as possible to guide the upgrade of the water-based paint industry.
