Let’s talk about the external anti-corrosion coating (PU) for liquid polyurethane asphalt pipes

Thread Content

Polyurethane asphalt is an excellent pipeline anti-corrosion coating; it is a two-component, solvent-free thermal spraying system composed of polyol compounds and isocyanate solutions. This anti-corrosion coating boasts excellent performance: it is easy to apply, results in a high-quality anti-corrosion layer, and exhibits strong impact resistance and flexibility. It is resistant to microbial corrosion, as well as scratches, wear, and dragging; it also has a certain degree of toughness, strong resistance to cathodic disbonding, good chemical stability, UV resistance, a long service life, low cost, good cost-performance ratio, and is environmentally friendly. It offers significant technical and economic advantages, making it particularly suitable for repairing damages, filling gaps, and restoring old anti-corrosion layers. It has now become the main material used for repairing pipeline anti-corrosion layers on an international scale, with broad application prospects and potential for further development.
