VM-6233R — epoxy powder for factory pipe coating

Other anticorrosion materials

VM-6233R is not a paint for on-site painting but an epoxy powder material for manufacturers of pipes, pipe fittings and pipe products. The powder is sprayed onto a heated pipe by manual mechanised methods or on automatic lines, and it cures by residual heat. The coating can be single-layer, the first coat of a two-layer system with VM-8352N or the first coat of a combined system with polyethylene or polypropylene. The service temperature is from −73 to +110 °C; the material is not intended for contact with drinking water and foodstuffs.
