Primer for Three Layer Coatings

3-Layer Systems - Epoxy Primers for 3-Layer Coatings

3-Layer coatings are popular corrosion protection systems in Europe and in many other countries around the world. A high level of performance can be achieved with proper system design, combining the best features of FBE (Fusion Bonded Epoxy) and stabilized PE (Polyethylene) or PP (Polypropylene):

- The FBE primer achieves excellent adhesion to the steel
and chemically bonds with the adhesive layer
- The adhesive provides the necessary tie-layer between the FBE primer and the outer PE or PP layer
- The PE/PP layer provides a though flexible coating with outstanding resistance to mechanical damage

Application process

 

Resicoat pipe powders should be applied to cleaned near-white metal (e.g. acc. SSPC SP 10) steel pipe surfaces having an open and angular pattern and a surface profile of 50-100 µm (2-4 mils). Appropriate chemical treatments are recommended. The epoxy layer provides corrosion protection and offers a good adhesion to the mechanical resistant thermoplastic layer. Recommended film thickness is 150-300 µm (6-12 mils).
