Common types of anti-rust paints are 1. Zinc-rich primer 2. Epoxy primer 3. Iron oxide red primer 4. Polyurethane paint In the selection of anti-rust paints, there are many types available on the market, and each paint has its specific anti-rust mechanism and applicable scenarios.

Epoxy anticorrosion primer is particularly suitable in the following cases: Highly corrosive environment Marine environment Heavy industrial equipment Buried pipelines and storage tanks Bridges and building steel structures Concrete protection

The coating film of two-component polyurethane coatings is very dense and has excellent water resistance, which can effectively prevent rainwater and accumulated water from penetrating into the interior of the building.

Although some antifouling boat paints may have certain anti-corrosion functions and strong adhesion, in order to ensure the long-term stability and protection of the coating, primer is still recommended in most cases.

Water-based metallic paints may change color in high temperature environments, especially under extreme temperature conditions. The causes of discoloration are usually related to the chemical composition of the paint, the color itself, changes in molecular structure when the temperature is too high, and the curing process of the coating.

Acrylic paint is a common type of paint in the automotive industry, which is popular for its ease of use, fast drying speed and high gloss effect. Acrylic paint usually exists in one-component or two-component form. Two-component acrylic paint needs to be mixed with a curing agent for curing to improve its durability and scratch resistance.

Epoxy zinc-rich primer is an epoxy resin primer containing a high proportion of zinc powder. Its main feature is to provide excellent anti-corrosion performance through the cathodic protection of zinc powder. Epoxy zinc-rich primer can form a dense protective layer on the surface of zinc metal, which can not only prevent the penetration of corrosive media, but also provide active protection when the coating is damaged.

Oil-based polyurethane paint is superior to water-based paint in terms of wear resistance, impact resistance and scratch resistance, and is suitable for high-intensity use scenarios. Although water-based paint is not as durable as oil-based paint, it is fully capable of being used in daily home environments.

Water-based metallic paint usually requires a good adhesion foundation, so the effect of the paint on wood may not be as ideal as on metal surfaces. In particular, the humidity fluctuations and texture changes of wood may affect the stability of the coating.

The color of high build primer is not single and fixed. Different manufacturers and application scenarios will use primers of different colors. Common colors are gray, reddish brown, white, black, green, etc.
