As a first priority, pipes and fittings, cooling water lines in ships, and pipelines in wastewater treatment plants and power plants must be permanently protected against corrosion.
A layer of VESTOSINT® polyamide 12 powders plays an essential role in ensuring this protection.
The coating also shows very good chemical resistance to such operating media as grease, oils, and hydraulic fluids.
VESTOSINT® shows excellent stress crack resistance and wear resistance.
Thanks to their smooth, non-porous surface, VESTOSINT® coatings are not susceptible to microbial growth and are easy to clean (microbiological test in accordance with Working Specification W 270 of the German Technical and Scientific Association for Gas and Water (DVGW)).
The powders are usually applied in the fluidized-bed process. For on-site repair work or coating pipe bushings and tunnels, the flame-spray process is particularly favored.
