1.Epoxy primer coating.The first layer with epoxy powder (FBE> 100um). Directly coated at the pipe surface. Ensure the overall coating has good adhesion at higher temperatures.
2.Copolymer adhesive. Mian component for this layer is a polyolefin. The thickness of the adhesive ranges from 170um to 250um.To make sure the top anti-corrosion coating is adhesives at the primer coating and also the pipe surface.
3.Anti-corrosion Coating (PE layer). The top layer is extruded polyethylene, the thickness of this layer is from 2.5 mm to 3.7 mm. It is polyethylene which has advantages to anti-water, electrical resistance, and anti mechanical damage. It is a very important layer.
