What is the surface coating for resin concrete pipe tops?

Resin-mix pipe surface coating is a two-component, high-solids coating based on a resin mix. It is widely used in drinking water tanks, water pipelines, and water tanks. It uses thermosetting epoxy resin as the primary raw material, with air as the dispersion medium. Using high-speed airflow and electric charge attraction, the powder is evenly sprayed onto the preheated steel pipe surface. Under high temperature, the powder melts into a uniformly thick anti-corrosion layer.

What is the performance of resin-mix pipes?

Fiberglass reinforced plastic pipe manufacturers' coatings are solvent-free, eliminating the need for fire prevention measures during application. They cure quickly, can be applied in thicknesses ranging from tens to hundreds of microns, and offer excellent toughness, resisting cracking when the pipe is bent. Advantages include strong adhesion to metal surfaces, excellent bonding and cathodic disbonding resistance, ease of repair, and strong resistance to soil stress, making them suitable for most harsh corrosive environments, such as those with high salt, alkaline, and cold temperatures. However, FBE is susceptible to impact damage and has a high water absorption rate, requiring stringent rust removal requirements on the steel pipe surface.
