The advantages of water-based dip coating are constantly highlighted and the industry is developing towards standardization and low carbonization.
Water-based dip coating refers to coatings that use water as a dispersion medium instead of organic solvents in whole or in part, and are painted by dip coating. It is one of the subcategories of water-based industrial coatings. According to different raw materials, water-based dip paint can be divided into water-based acrylate dip paint, water-based polyester or alkyd dip paint, water-based epoxy ester dip paint, acrylic emulsion dip paint, etc.; depending on the curing mechanism, it can It is divided into oxidative drying type dip paint, cross-linked curing type dip paint, and volatile self-drying type dip paint.
According to the “Research Report on Market Monitoring and Future Development Prospects of China’s Water-based Dip Paint Industry from 2023 to 2027” released by the Industrial Research Center It is shown that water-based dip paint has the advantages of high hardness, good leveling, strong corrosion resistance, good acid and alkali resistance, convenient construction, low carbon and environmental protection, bright and plump paint film, and strong adhesion. It is mainly suitable for complex structures, Assembly line painting scenarios that are difficult to spray are widely used in automobiles, petrochemicals, electric power, industry, ships, textiles, metallurgy, steel, construction, machinery and other fields. Among them, automobiles, engineering vehicles, and industrial machinery are currently the largest application areas of water-based dip coating.
Traditional solvent-based paints contain heavy metal elements such as benzene, formaldehyde, and lead, which pose a great threat to the human living environment and human health. At the same time, traditional solvent-based paints also contain VOCs (hydrocarbons), which pollute urban air. In recent years, with the continuous advancement of domestic dual-carbon goals and the continuous strengthening of environmental protection efforts, water-based dip paints with non-toxic, low-carbon and environmentally friendly characteristics have become the main substitute for traditional solvent-based paints. Currently, with the domestic automotive, industrial, and machinery The field is developing rapidly, its market demand is increasing, and the industry shows good development prospects.
As an important type of water-based paint, water-based dip paint is currently experiencing a rising trend of standardized development against the background of continuous improvement of domestic industry standards. The new national standards GB24409-2020 “Limits of Hazardous Substances in Vehicle Coatings” and GB30981-2020 “Limits of Hazardous Substances in Industrial Protective Coatings” officially implemented in December 2020 have added the VOC content of water-based coatings, solvent-free coatings, and radiation-cured coatings. The limit value provides a clear reference standard for the VOC content of domestic water-based dip paints. As a result, the domestic water-based dip coating industry will continue to develop in the direction of standardization and low carbonization in the future.
Industry analysts personnel said that in recent years, against the background of the continuous advancement of domestic dual-carbon goals and the continuous strengthening of environmental protection supervision, water-based dip coating As a type of low-carbon and environmentally friendly water-based coating, paint has been widely used in automobiles, machinery, industry, chemical industry, construction and other fields, and the industry development prospects are good. The domestic companies that are developing water-based dip coating market mainly include Qingtian Material Technology, Haolisen Paint, Carbaoli Group, Sanhe Chemical, etc. In order to promote the accelerated development of the domestic water-based dip coating industry, local companies still need to continuously improve their technical levels and accelerate the research and development of innovative products.
