JT-7800 Grey High-Edge Cathodic Electrocoating For Long-Lasting Coating

Composition
Composed of two components: emulsion and pigment paste. The main resin consists of chain-extended epoxy resin, isocyanate crosslinking agent, and toughening agent, with the addition of independently developed high-edge-protection resin. After acid neutralization, it forms an emulsion. Epoxy resin acts as the dispersion resin, combined with pigments and fillers to form a ground pigment paste.
 
Features

• Excellent edge corrosion resistance
• High edge coverage with outstanding film appearance and mechanical properties
• Superior sedimentation resistance and bath stability
• Free from heavy metals such as lead, low VOC content, and environmentally friendly

Applications

• Widely used in corrosion-resistant coatings for automobiles, auto parts, agricultural machinery, and various steel components.
• Particularly suitable for e-coating applications that require high edge corrosion resistance.
