Coil coating resin
CJ-672 PE Topcoat Resin
CJ-672 is a saturated polyester resin for PE topcoat systems, supporting high gloss, strong adhesion, good film fullness, forming flexibility, and practical outdoor durability in coil coating applications.
- High gloss
- Strong adhesion
- Good film fullness
- Practical outdoor durability
What CJ-672 is built for
CJ-672 is developed for PE topcoat systems that require high gloss, strong adhesion, good film fullness, forming flexibility, and practical outdoor performance. It provides a balanced resin path for standard visible-surface applications.
Benefits
High gloss
Supports clean and bright surface presentation for visible metal applications.
Strong adhesion
Supports reliable bonding performance in PE topcoat systems.
Good film fullness
Helps create a smooth and well — built coating finish for practical surface use.
Forming flexibility
Helps the coating layer maintain integrity during forming and fabrication.
Typical applications
Construction panels
Used in PE topcoat systems for roofing sheets, wall panels, and other prepainted building materials requiring balanced appearance, gloss, forming support, and practical outdoor durability.
General outdoor prepainted steel
Suitable for standard outdoor metal applications requiring balanced surface appearance, good film fullness, forming flexibility, and cost-performance durability.
Appliance metal panels
Used in selected appliance panel systems requiring stable gloss, smooth appearance, adhesion support, and practical coating performance.
