Top 10 2LPP Coating Suppliers in China 2025 - Blog

Introduction to 2LPP Coating

2LPP (Two - Layer Polypropylene) coating is a widely used anti - corrosion coating system for steel pipes in various industries, especially in the oil and gas sector. It consists of an epoxy primer and an outer layer of polypropylene. The epoxy primer provides excellent adhesion to the steel surface, while the polypropylene outer layer offers high mechanical protection, good chemical resistance, and long - term durability. This combination makes 2LPP coating suitable for buried or submerged pipelines, protecting them from corrosion, abrasion, and environmental factors, thereby extending the service life of the pipes and reducing maintenance costs.
