Specifically formulated for construction in coastal and marine environments where elevated chloride deposition demands maximum corrosion protection. HDP technology advances beyond SMP by incorporating higher molecular weight polyester resins with specialized cross-linking agents and advanced UV stabilizers, achieving 3-4 times the gloss retention of standard PE. The three-layer architecture with zinc phosphate conversion coating, chromate-free primer, and HDP topcoat has been validated through 1500+ hours of neutral salt spray testing per ISO 9227.

• HDP Coating Technology: High durability polyester with advanced UV stabilization delivers 3-4x better gloss retention, extending maintenance intervals in high-UV coastal environments.
• Superior Salt Spray Resistance: Validated through 1500+ hours of ISO 9227 testing with no blistering and minimal creep, confirming marine atmosphere suitability.
• Z275 Heavy Zinc Protection: 275 g/m² double-side zinc coating provides robust sacrificial protection at cut edges and punched holes in coastal service.
• Chromate-Free Primer: Environmentally compliant corrosion-inhibiting technology meets EU REACH and RoHS requirements while maintaining anti-corrosion performance.
• Three-Layer Architecture: Conversion coating, primer, and HDP topcoat work synergistically through multiple barrier and inhibition mechanisms.
• Coastal Climate Optimized: Formulation accounts for combined UV radiation, salt deposition, high humidity, and wind-driven rain typical of coastal construction sites.
