3230 HK8660 Solvent-Free, Wear-Resistant Epoxy Coating
Product Description
Product Introduction
3230 is a two-component, solvent-free epoxy coating. Its cured film is tough and exhibits excellent adhesion, flexibility, abrasion resistance, and impact resistance, while also offering superior chemical resistance and long-lasting corrosion protection.
Application areas
This product is suitable for application in humid environments. It is used for long-term corrosion protection of cooling water pipes subjected to fluid erosion, crude oil pipelines, the inner linings of pressure conduits in hydropower stations, steel piles at docks, bridges, sluice gates, and the corrosion‑resistant lining of feed chutes for ores and coal.
