Road metal fence is more common, metal fence for decorative, weatherability and other performance requirements are higher. Fence can use more types of paint, the specific use of what kind of paint, according to the anti-corrosion requirements to be achieved, and the use of the environment to determine. Here we look at the next environment under the metal fence recommended anti-corrosion paint matching program
One of the most economical: the use of time 2-3 years, for the general corrosive environment, you can use alkyd paint primer using alkyd anti-rust paint, the film thickness of 80um finish using alkyd enamel, the film thickness of 60um
Second, the moderate corrosion environment: acrylic finish good weather resistance, epoxy primer strong adhesion. Primer can use epoxy primer, film thickness in 80um topcoat using acrylic finish, film thickness at 60um
Third, high-performance anti-corrosion: acrylic polyurethane topcoat is a high-performance anti-corrosion finish, salt spray, excellent anti-corrosion primer can use epoxy primer, film thickness of 80um. Topcoat can be acrylic polyurethane finish, the film thickness of 60um.
Fourth, the severe corrosive environment: in the use of severe corrosion environment supporting system, anti-corrosion more than 10 years, the color retention of light excellent primer using epoxy zinc-rich primer, paint in the 70um intermediate paint can use epoxy paint, The film thickness is 70um. Topcoat use metal fluorocarbon paint, film thickness at 60um.
