Standox EP Primer Surfacer U7200 is an epoxy-based, universal, chromate-free primer surfacer that provides corrosion protection for steel and galvanised substrates. It has excellent storage durability. It offers good insulation of thermoplastic substrates and is also available in the SprayMax spray can for smaller repairs and sand-through areas. The finish is comparable to that achieved with an HVLP spray gun.
