The market scale of heavy-duty anti-corrosion coatings continues to expand, and the competitive advantages of local companies need to be improved

Heavy-duty anti-corrosion coating refers to a type of anti-corrosion coating that can be used in relatively harsh corrosive environments and can achieve a longer protection period than conventional anti-corrosion coatings. Heavy-duty anti-corrosion coatings have the advantages of large dry film thickness, long service life, and strong adhesion ability. They are widely used in shipbuilding, industrial protection, bioengineering, container manufacturing and other fields. There are many types of heavy-duty anti-corrosion coatings, including special anti-corrosion coatings, fluorocarbon paints, solvent-free anti-corrosion coatings, epoxy resin paints, silicone high-temperature resistant paints, etc.

According to the “2022-2027 Heavy-Duty Anticorrosive Coatings Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, in recent years In the past few years, my country’s heavy anti-corrosion coating production has maintained a steady growth trend, benefiting from sufficient supply of raw materials and strong downstream demand. In 2021, my country’s heavy anti-corrosion coating production reached 4.912 million tons, a year-on-year increase of 7.2%.

In terms of market segments, fluorocarbon paint, epoxy resin paint, and solvent-free anticorrosive coatings are the mainstream products of heavy anticorrosive coatings. Fluorocarbon paint uses fluororesin as raw material and has the advantages of corrosion resistance and low temperature. It can be subdivided into three categories: fluorocarbon exterior wall paint, various fluorocarbon anti-corrosion paints and metallic fluorocarbon paint; epoxy resin paint is mainly made of epoxy resin. Film-forming substances have the advantages of water resistance, good electrical insulation performance, chemical resistance, etc., and are widely used in electrical insulation, shipbuilding and other fields; solvent-free anti-corrosion coatings are environmentally friendly heavy-duty anti-corrosion coatings that do not volatilize harmful gases and are suitable for use in areas with poor ventilation. in the production environment.

Heavy-duty anti-corrosion coatings are widely used in the shipbuilding industry and industrial protection fields, with an application proportion of up to 80.0%. Benefiting from national policy support and the rapid development of the manufacturing industry, my country’s shipbuilding completion volume continues to increase. According to statistics from the Ministry of Industry and Information Technology, my country’s shipbuilding completion volume reached 39.703 million deadweight tons in 2021, a year-on-year increase of 3.0%. In order to prevent marine air pollution, seawater corrosion and the adhesion of marine organisms, ships need to be painted with heavy-duty anti-corrosion coatings. Against this background, the scale of my country’s heavy-duty anti-corrosion coatings market continues to expand. In 2021, my country’s heavy-duty anti-corrosion coatings market will reach 118.76 billion yuan, a year-on-year increase of 10.8%.

my country’s heavy-duty anti-corrosion coatings industry has a high degree of concentration, but the leading companies are mostly Sino-foreign joint ventures and foreign-invested companies, and local companies have a low market share. Jotun Paints of Norway, AkzoNobel of the Netherlands, Hempel of Denmark, and Japan’s Midco Chemicals are the main suppliers of heavy-duty anti-corrosion coatings in my country. Local enterprises in my country’s heavy-duty anti-corrosion coatings mainly produce mid- to low-end products, and the scale of the enterprises is relatively small.

Industry analysts said that heavy-duty anti-corrosion coatings have the advantages of corrosion resistance, high temperature resistance and long service life, and are widely used in many industrial fields. . my country’s heavy-duty anti-corrosion coatings industry is developing rapidly, but local companies are small in scale and lack competitive advantages. Foreign-funded enterprises and Sino-foreign joint ventures occupy the main market share of my country’s heavy-duty anti-corrosion coatings. As local companies continue to innovate in production technology, the localization process of my country’s heavy-duty anti-corrosion coatings will continue to accelerate.
