RAL1000 green beige special hammer finish pure Epoxy Powder Coating
We offer various anti-corrosive options that can be used for electrostatic powder coating. Epoxy powder coating is a fantastic low cost option for those looking for excellent corrosion protection while staying within the project budget. This coating is commonly used for waste treatment, water valves, and other metal coatings in both thin and heavy builds.
Features
1. Very good adhesion with the substrate and epoxy.
2. Strong permeability and corrosion resistance
3. The coating has excellent high temperature cathodic disbonding resistance.
4. High surface hardness, strong coating density, good ability to resist plant roots puncture
