Q1: Why is a specialized varnish required for PET substrates?
A: PET has a smooth, chemically inert surface with low polarity, making it difficult for standard coatings to adhere properly. This varnish is formulated with tailored adhesion promoters and resins that ensure strong bonding, preventing delamination and providing long-term durability on PET films and rigid sheets.

Q2: What types of finishes and functional properties does this varnish offer?
A: It is available in high-gloss, matte, and satin finishes, while also providing exceptional scratch resistance, chemical stability, and barrier properties. The coating enhances both visual appeal and protection, making it suitable for demanding applications where aesthetics and performance must coexist.

Q3: Are there specific application or curing guidelines for PET coatings?
A: For optimal results, surface pretreatment (e.g., corona or plasma treatment) is often recommended to increase surface energy. Application via spray, roll-coat, or curtain methods should ensure uniform coverage. Curing typically involves UV or thermal processes, depending on the formulation, and parameters should be verified through pre-production testing.
