Superior Anti-Corrosion Properties

This Epoxy Powder Coating provides an exceptional protective layer for drinking water pipes, preventing rust, wear, and chemical attack. Its high-performance formula ensures long-lasting durability while maintaining water potability, making it the ideal choice for internal and external pipe surfaces in potable water systems.


Customizable and Safety Compliant

Available in multiple shades as per the RAL card, this coating combines aesthetic flexibility with strict adherence to health and safety standards. The coating is non-toxic when fully cured, solvent-free, and certified safe for drinking water, offering peace of mind for municipal and industrial users alike.


Easy Application and Reliable Performance

Designed for application using an electrostatic spray method, the coating cures efficiently at recommended temperatures, ensuring a consistent film thickness (60-120 m). The hammered, structured finish provides enhanced resistance to impact, abrasion, and handling stresses during installation and operation.
