Our water-soluble epoxy ester resin system features a high-performance, single-component primer and topcoat formulation with rapid-drying capabilities and rust-preventive properties, specifically engineered for ferrous metal substrates such as structural steel, railings, machinery, and equipment. This product delivers enduring corrosion protection for both interior and exterior metal surfaces while maintaining compatibility with water-based or alkyd/oil-based topcoatings. The primer exhibits exceptional coverage, uniform application, sag resistance, abrasion resistance, and industry-leading durability.
These resins are specifically engineered for automotive chassis, underbody, frame, and suspension components, as well as advanced protective coatings for other engineering metals and equipment.
Serving as our ongoing commitment to sustainability, we prioritize the development of waterborne alternatives to replace conventional solventborne coatings.
Product Properties:
Self-emulsifying capability: No external emulsifier required, demonstrating superior water resistance and corrosion protection
Film-forming mechanism: Oxidative cross-linking enables substitution for traditional solvent-based alkyd and epoxy ester resins
Process compatibility: Compatible with conventional solvent-based paint manufacturing workflows, enabling direct resin grinding
Stability profile:
• Mechanical stability under operational conditions
• Long-term storage stability without performance degradation
