Powder epoxy (coating for fittings)
The epoxy resin powder coating provides reinforced protection of the fittings. These fittings are intended for use with TT pipes (highly corrosive soils) or PUR pipes (corrosive water).
The coating is produced by applying an epoxy powder on a previously shot-peened and heated fitting. The powder is applied by :
- electrostatic spray gun or
- dipped in a fluidized bed bath.
The blue epoxy coating has an average thickness of at least 250 microns.
Field of use
Fittings with this type of coating can be used buried in corrosive or highly corrosive soils or to transport aggressive or corrosive water.
Drinking water compatibility
The blue epoxy powder coating is compatible with drinking water and has a Sanitary Conformity Certificate (ACS).
Repairing the blue epoxy powder coating
Strip the damaged area and remove the oxidation.
Sand the coating with abrasive cloth around the damaged area to ensure good adhesion.
Clean, degrease and heat the surface before applying the epoxy (temperature about 50 °C).
Mix equal quantities of resin and hardener. Prepare small quantities (very short working time: 30 min at 40 °C).
Apply the epoxy with a spatula or a brush.
Allow to harden in a dry area and avoid handling.
