Can epoxy anticorrosive paint be used outdoors?
- 2018-07-18-

Epoxy paint has the advantages of good adhesion, tough film, anti-corrosion, anti-rust and moisture resistance. It is widely used in anti-rust primer for steel structure and anti-rust and anti-corrosion top coat for indoor steel structure. However, epoxy paints should not be used directly as a topcoat in the wild, that is, epoxy paints cannot be exposed to the sun for a long time.

环氧 Epoxy paint cannot be used in the field for the following reasons:

The epoxy resin has poor weatherability because the epoxy resin is composed of at least two epoxy groups, and the epoxy chain is easily cracked under the illumination of the outer line of the purpura, forming a resin film to be pulverized. Therefore, epoxy antiseptic products cannot be used for field protection.

The resin has a good physical and mechanical function. What is outstanding is its strong adhesion to metal; its chemical resistance and oil resistance are also very good, especially the alkali resistance is very good.

环氧 Epoxy paint is used as a primer. Epoxy iron red primer, epoxy zinc-rich primer, etc. can be matched with acrylic polyurethane paint, fluorocarbon top coat, etc. for field weathering coating.

Can epoxy paint be used without a curing ?

The adhesive of epoxy paint is strong, the film is tough, the alkali resistance is excellent, the insulation function is good, and the chemical good. However, the curing is slow, and the epoxy antirust paint is easy to be powdered outdoors.
