Epoxy coal tar pitch coating materials have the highest price, and the most cost is epoxy resin. The epoxy resin content should be between 25 and 30% (weight percent), which is the best positioning for cost and quality. If the epoxy resin is too low (15% or less), the adhesion, mechanical properties and chemical resistance of the medium are greatly reduced, which will affect the corrosion resistance of the coating and cause corrosion of pipes and equipment in a short time.
However, the current domestic market competition is based on price. Therefore, some manufacturers have reduced the sales price by sacrificing product quality, regardless of the quality of the country's engineering. Following this will seriously affect the reputation of epoxy coal tar pitch, so that this excellent anti-corrosion material that has been used in China and abroad for more than 50 years has been tarnished.

Nowadays, the so-called epoxy coal tar pitch coatings appear on the market, the price is as low as less than 12 yuan per kilogram. How can the low-cost epoxy coal tar pitch coating epoxy resin content reach 25%? The coating performance can reach the standard. Is it required? Can the equipment and pipelines of the factory be protected as expected? The user's investment can be worth the money!
Xiaobian has something to say: In order to maintain the excellent quality of epoxy coal tar pitch and make it last for a long time, it is recommended that domestic epoxy coal tar pitch production plants, epoxy coal tar asphalt construction users' anti-corrosion companies and engineering investors jointly control the epoxy. The quality and coating quality of coal tar pitch coatings are strictly produced, inspected and constructed according to national standards to ensure the quality of the anti-corrosion layer and to carry forward this long-established old product.
