Q1: What does "reverse primer" mean, and when is it typically used?
A: A reverse primer is applied between the substrate and a functional coating or ink to solve adhesion challenges on difficult surfaces (e.g., plastics, films, pre-printed materials). It is used when direct coating fails, ensuring reliable bonding where traditional primers may not work.

Q2: What types of difficult substrates can this primer effectively treat?
A: It is designed for low-surface-energy materials such as polyolefins (PE, PP), silicone-treated films, UV-cured surfaces, glossy inks, and certain coated metals. It modifies surface properties to enable strong adhesion of topcoats, laminates, or specialty inks.

Q3: Does applying a reverse primer affect production efficiency or final product performance?
A: It can improve production yield by reducing coating defects and adhesion failures. Once properly applied and dried, it does not negatively impact the performance of the final product—instead, it enhances durability, scratch resistance, and overall finish quality. Process compatibility should be validated through testing.
