Epoxy coal pitch coating has a wide range of applications, but industry development still faces challenges

Epoxy coal pitch coating was produced in the 1960s. It is a subdivision of anti-corrosion coatings and consists of two-component self-drying coatings. Epoxy coal pitch coating has the advantages of strong corrosion resistance, low production cost, good water resistance, and long service life, and is suitable for use in large-area construction. Driven by technological innovation, my country’s epoxy coal pitch coating production technology has matured and has been widely used in the field of construction engineering.

According to the “2022-2027 China Epoxy Coal Asphalt Coatings Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center 》 shows that the upstream of the epoxy coal pitch coating industry chain is the supply of raw materials, with epoxy resin and petroleum asphalt accounting for the main production costs. Driven by market demand, my country’s epoxy resin production continues to increase. In 2021, my country’s epoxy resin output reached 1.376 million tons, a year-on-year increase of 5.1%. Affected by factors such as the international situation and production costs, my country’s petroleum asphalt production has declined in recent years, but it can fully meet my country’s epoxy coal asphalt coating production needs. According to data from the National Bureau of Statistics, my country’s cumulative petroleum asphalt production in 2021 will be 55.517 million tons, a year-on-year decrease of 11.5%. Benefiting from sufficient supply of raw materials, my country’s epoxy coal pitch coating production continues to grow.

The downstream of the epoxy coal pitch coating industry chain is in application fields, including shipbuilding, petrochemical industry, transportation, water conservancy projects, construction projects, etc. The shipbuilding field is the largest demand side for epoxy coal pitch coatings, accounting for 50.0% of the total demand. The hull of a ship is mainly made of metal materials and is easily affected by seawater salinity, temperature, etc., causing hull corrosion. Epoxy coal pitch coating has good corrosion resistance, wear resistance and impact resistance, and can protect the hull. my country’s shipbuilding completion volume has long maintained its leading position in the world. Driven by application demand, my country’s epoxy coal pitch coating industry will gain broad development space.

Although my country’s epoxy coal pitch coating industry is developing rapidly, it still faces many challenges. On the one hand, my country’s epoxy coal pitch coating manufacturers are small in scale and lack industry standards. In addition, some companies cut corners and cut corners, resulting in uneven product quality and failure to meet domestic market demand. On the other hand, the solvent content of epoxy coal pitch coatings is relatively high. High. During the construction process, solvent volatilization can easily cause environmental pollution and endanger the health of users. At present, many manufacturing companies in my country have begun to develop solvent-free epoxy coal pitch coatings to solve the industry’s environmental pollution problems.

Industry analysts said that with the rapid economic development and continuous upgrading of technology, the market demand for epoxy coal pitch coatings in my country is gradually released, and the industry The development prospects continue to improve. The sufficient supply of raw materials such as epoxy resin and petroleum asphalt has driven the continuous increase in the production of epoxy coal pitch coatings. However, at present, environmental pollution and lack of industry standards are still major problems that need to be solved in my country’s epoxy coal asphalt coating industry.
