Let's take epoxy cement floor paint as an example to explain some of its characteristics:
First, the composition:
It is mainly used for epoxy resin, color paste, filler (quartz powder, talc powder, titanium dioxide, etc.), additives (leveling agent, defoamer) and corresponding curing agent. It is mainly used on cement floor.
Second, the applicable places:
Electronics, electrical appliances, machinery, communications, food, medicine, molds, clothing, plastics, tobacco, chemicals, etc. require wear-resistant, impact-resistant places, especially where forklift trucks, heavy-duty hand forklifts, and automobiles are required.
Third, the characteristics:
1, impact resistance, high load, wear resistance; 2, the overall seamless, easy to clean; 3, moisture, dust; 4, resistant to general chemical corrosion; 5, can do non-slip or matte effect.
Fourth, the construction process:
1. Base surface treatment;
2. Rolling the base oil;
3, squeegee mortar coating;
4, scraping putty;
5, roll brush surface coating or spray surface coating or sandblasting for anti-slip treatment.

This section of the coating industry development
In recent years, China's coatings industry has grown at a rate of 5%-10% higher than GDP, driven by high-growth real estate, automobiles, ships, and other downstream industries, making it the second largest producer and consumer of coatings in the world.
From January to December 2006, China's coatings, inks, pigments and similar products manufacturing industry achieved a total industrial output value of 191,934,746 thousand yuan, an increase of 26.19% over the same period of the previous year; the annual sales of accumulated products reached 185,825,254,000 yuan, compared with the same period of the previous year. The growth was 25.94%; the total accumulated profit for the year was RMB 12,513,388,000, an increase of 25.7% over the same period of the previous year.
In terms of import and export, although the Chinese coatings industry will continue to face pressures such as trade barriers and RMB appreciation, as the world economy and the Chinese economy continue to grow rapidly, domestic and foreign demand for coatings continues to expand, and from January 1, 2006 Since the beginning of the day, the state has cancelled the export tariffs on related products, which is generally beneficial to the development of the coatings industry.
