1.Raw material: epoxy resin powder coating has no solvent, and it is food grade powder and environmental protection coating. Liquid epoxy paint has irritating odor.
2.The process of anti-corrosion: epoxy resin coating is thermal spraying, reacts with the 250℃ Steel Pipe and form a steel plastic alloy layer. Liquid epoxy paint spray into the steel tube with spray gun for long curing time.
3.Adhesion: the former is mechanical adhesion, chemical bond with electrostatic bonding force. The latter is only mechanical interlocking.
4.The coating thickness: the former is 300-500um, the latter is 30-80um.
5.Corrosion resistance: the former is corrosion resistance, abrasion resistance, impact resistance. The latter is rust proof, no corrosion, no water erosion, play a drag reduction role.
6.Coefficient of friction: the former is 0.0086, and the latter is 0.012.
7.The theoretical life span: the former is 50 years, the latter is 3-5 years.
PuLanke Industrial Technology specialized in manufacturing and supplying Epoxy Coated Steel Pipe, 3LPE coated steel pipe for many years.
