ERW Steel Pipe Coating Zinc Phosphate Pigment
Product introduction
This eco-friendly zinc phosphate pigment delivers superior corrosion protection by reacting with the steel surface to form a dense, insoluble passivation film that effectively blocks moisture and corrosive agents. It offers excellent compatibility with various resin systems, ensuring strong coating adhesion and long-term durability while fully complying with global environmental regulations by eliminating toxic heavy metals.
Product feature and application
ERW Steel Pipe Coating Zinc Phosphate Pigment features superior corrosion resistance by forming a stable passivation layer that enhances adhesion and durability in harsh environments. It is widely applied in epoxy and alkyd coatings for oil and gas pipelines, marine structures, and industrial steel protection, offering an eco-friendly alternative to traditional anti-corrosive pigments while ensuring long-term performance and compliance with environmental standards.
Production details
ERW Steel Pipe Coating Zinc Phosphate Pigment is an eco-friendly anti-corrosive pigment specifically designed for welded steel pipes, functioning by chemically reacting with the metal substrate to form a dense, insoluble zinc phosphate passivation film that significantly enhances coating adhesion and corrosion resistance. Featuring a lead-free and chromium-free formulation, it is highly compatible with epoxy, alkyd, and water-based resin systems, making it ideal for harsh environments such as marine, chemical, and oil and gas transportation. To ensure optimal performance, it requires proper surface preparation including degreasing, pickling, and surface conditioning, with a recommended coating weight of 1.5–3.0 g/m² to maintain superior protection even under low-temperature and high-humidity conditions.
