Water based pipe coating : ウィキペディア英語版 | Water based pipe coating
Water based pipe coatings are an environmentally friendly coating that is applied to the inner and outer surfaces of ductile iron pipe. The coating serves to protect the water supply lines from corrosion whether from the outside or the inside . It also serves to protect the drinking water from contamination. The coating is an emulsion manufactured using asphaltene and water primarily, with other raw materials according to the manufacturer’s specifications. ==History== Water based coatings began development in the late 1980s. In the early 1990s they began to be widely used, specifically marketed towards drinking water supply lines. Previously, water supply lines were coated using a harmful solvent based coating, using such solvents as benzene, toluene, hexane and other volatile organic compounds (VOC).
