Resicoat R-726 Primer in 3-Layer coating
Resicoat epoxy primers for
3-Layer coatings
3-layer coatings are popular corrosion protection systems used in many countries. This systems guarantees high resistance to chemical attack, while ensuring perfect adhesion and outstanding resistance to cathodic disbondment. The low application temperature of some Resicoat powders in a range of 180 – 220° C results in considerable cost savings of energy and polyethylene consumption.
A high level of performance can be achieved by combining the best features of FBE and stabilized PE (Polyethylne) and PP (Polypropylene)
-
The FBE primer prevents cathodic disbondment
-
The copolymer adhesive provides a tight bond between the FBE primer and the outer PE/PP layer
-
The PE/PP layer provides a tough flexible coating with outstanding resistance to mechanical properties.
