Coil coating resin
CJ-563 Primer Resin
CJ-563 is a saturated polyester resin for primer systems, supporting substrate bonding, epoxy compatibility, forming flexibility, and stable processing in coil coating applications.
- Strong substrate adhesion
- Epoxy compatibility
- Forming flexibility
- Processing stability
What CJ-563 is built for
CJ-563 is developed for primer systems that require strong substrate bonding, epoxy compatibility, forming flexibility, and practical solvent resistance. It supports stable application and production control in coil coating lines.
Benefits
Strong adhesion
Supports reliable bonding to metal substrates.
Epoxy compatibility
Works well in epoxy — based primer systems.
Forming flexibility
Helps the primer layer maintain integrity during forming and fabrication.
Stable processing
Supports stable line application and curing response.
Typical applications
Building and construction panels
Used in primer systems for roofing sheets, wall panels, and other prepainted building materials requiring substrate adhesion, corrosion support, and stable system compatibility.
Home appliance metal panels
Suitable for appliance coating systems requiring stable adhesion, forming flexibility, epoxy compatibility, and consistent primer support.
Epoxy-based primer systems
Used in primer formulations where epoxy compatibility, solvent resistance, curing response, and production stability are required.
Technical highlights
