Powder Coating for Electrostatic Spray Application on Cold Surfaces
Product Description
MT R4-ES HJ601R is a high quality thermosetting epoxy powder coating for the corrosion protection of valves and fittings, manufactured from cast iron or steel. The powder coating is applied in one layer on cold surfaces by electrostatic spray application. The adhesion of MT R4-ES HJ601R to the metal substrate provides long term protection of the coated component. It ensures a reliable conservation to the function and value of the parts for the common water and gas distribution network. The applicator benefits from a modern and environmentally friendly process. Drinking water approvals are available.
