Product Details

Pipeline API5L With Polyurethane Solventless Coating

Polyurethane Coatings, which is recommended as protective coating and lining for underground & on ground pipelines. . It is 100% solids, applied by plural component airless spray equipment. It is ideally suited for the areas where higher DFT is required as protective barrier. The coating has excellent film build capabilities and can achieve 500 microns to 5000 microns DFT in single application with multiple passes.
