Copper Acrylate Self-Polishing Resin (CASPR) is an advanced environmentally responsive antifouling binder specifically designed for marine coatings. Through controlled hydrolysis in seawater, it gradually releases copper ions and renews the coating surface, providing long-term fouling prevention while complying with IMO and EU biocidal regulations.
Our products' Key Features & Advantages
| Property | Technical Benefit |
|---|---|
| Self-Polishing Effect | Hydrolyzes at 5-10μm/year, maintaining smooth hull surface and reducing drag (fuel savings up to 12%). |
| Copper Ion Release | Sustained Cu²⁺ release (0.5-2 μg/cm²/day) effectively inhibits barnacles/algae. |
| Eco-Friendly Formula | Replaces toxic TBT/Cu₂O; passes OECD 201/202 aquatic toxicity tests. |
| Broad Compatibility | Works with acrylic copolymers, rosin derivatives, and modern foul-release silicones. |
Target Applications
Commercial vessels (Cargo ships, tankers)
Offshore structures (Oil rigs, buoys)
Leisure boats (Yachts, fishing vessels)
Naval ships (With enhanced Cu⁺ stability for high-speed sailing)
