In terms of robustness, epoxy coatings are undoubtedly superior. Its high hardness and impact resistance allow it to withstand the pressure of heavy machinery and frequent trampling without cracking or wearing out.

In 1924, Lester Wire, an engineer at the New York State Department of Transportation in the United States, first used a special paint to mark road lines. This paint has higher wear resistance and reflectivity and is considered to be the prototype of modern traffic paint.

If both anti-corrosion and wear resistance are required, polyurethane primer and epoxy primer can be used together: first apply epoxy primer as an anti-corrosion layer, and then apply polyurethane primer or topcoat to improve wear resistance and anti-aging performance.

Uses of protective enamel paint: ● Industrial equipment protection 1. Chemical equipment 2. Power plant equipment 3. Oil and gas equipment ● Building and infrastructure protection 1. Steel structure building 2. Municipal facilities ● Household and daily necessities protection 1. Home appliances 2. Interior decoration ● Transportation protection 1. Cars and motorcycles 2. Ships and water vehicles.

Heavyweight acrylic and regular acrylic have the same basic ingredients, mainly composed of acrylic polymer emulsion, pigments, fillers and additives, so from a chemical point of view, they are compatible. There will be no obvious chemical reaction after mixing the two, nor will it cause stratification or separation.

The formula design of the epoxy primer determines its original viscosity. If the product has a high viscosity when it leaves the factory, direct use may cause difficulty in brushing or spraying. At this time, adding an appropriate amount of diluent can reduce the viscosity and improve construction performance.

Epoxy primer is an important part of the anti-corrosion coating system for aluminum products, especially suitable for use in severely corrosive environments. It has excellent adhesion and chemical resistance, and can form a hard protective film on the surface of aluminum to block the intrusion of moisture, oxygen and other corrosive substances.

Commonly used protective paint coatings: 1. Epoxy resin paint, 2. Polyurethane paint, 3. Alkyd resin paint, 4. Acrylic paint, 5. Chlorinated rubber paint, 6. Zinc powder paint, 7. Silicate paint.

2K acrylic paint, referred to as 2K paint, refers to a two-component paint system. The two components of 2K paint are base and hardener. Before use, these two parts need to be mixed in a certain proportion, and after mixing, a chemical reaction occurs to form a tough and durable coating.

For metal materials, the use of primer is usually necessary. Metal surfaces are usually smooth and easily corroded by air and moisture. Directly applying 2K acrylic paint may result in insufficient adhesion and easy rust.
