UV PP Pretreatment Coating

UVINKPRO UV PP Pretreatment Coating is a UV printing pretreatment coating for tested pp substrates. It is not UV ink and it is not UV varnish. Test adhesion, curing, surface preparation, and ink-system compatibility on the actual substrate before production.

Recommended Substrates

• Recommended for PP sheets, PP packaging materials, PP boards, and other low-surface-energy plastic substrates.
• Used to improve adhesion, surface performance, or bonding stability before or after printing depending on the production workflow.
• Always test on the actual substrate and curing setup before full production.

Compatibility Notes

• Confirm the coating process together with your UV ink, printhead configuration, and curing energy before bulk use.
• Check whether the surface requires cleaning, flame treatment, corona treatment, or another pre-treatment process.
• For stable production, confirm application thickness, drying or curing conditions, and final adhesion requirements.

Typical Applications

• Industrial decoration, promotional products, rigid signage, packaging, and specialty surface printing.
• Workflows where buyers need better adhesion and more reliable surface performance on difficult materials.
• Suitable for sampling, small-batch production, and scale-up after adhesion testing is approved.

Surface Preparation Checklist

• For PP and similar low-surface-energy plastics, surface treatment is often critical before printing.
• Run a small adhesion test before production and confirm whether wiping, degreasing, flame treatment, or corona treatment is required.
• Check coating thickness, flash-off or drying time, and UV curing energy before moving from sample work to batch production.

Workflow Notes

• Confirm whether the coating is used as a primer, adhesion promoter, or post-treatment step in your printing workflow.
• Buyers usually validate cross-hatch adhesion, tape test results, scratch resistance, and final appearance on the real substrate first.
• Use this product only after confirming compatibility with your UV / UV LED printing process and target material.

Buying Notes

• If the same material is supplied by multiple factories, test each substrate batch because surface energy can vary.
• For export or contract production, lock down the approved process window before ordering larger volumes.
• When in doubt, request a sample workflow or confirm the intended application with your production engineer before purchase.
