Q1: What is the primary purpose of using a UV white base coating?
A: Its primary purpose is to create a high-opacity, uniform white background on transparent or dark-colored substrates, significantly improving color vibrancy, contrast, and readability of overprinted graphics or text. It ensures consistent print quality and acts as a functional barrier layer.

Q2: On which substrates and applications is this coating most beneficial?
A: It is essential for clear films (PET, PVC, OPP), tinted plastics, metalized surfaces, and dark papers used in applications such as transparent labels, backlit displays, premium packaging, automotive decals, and industrial signage where underlying colors or textures must be masked.

Q3: Are there specific curing or application guidelines to achieve optimal opacity and adhesion?
A: Yes. Apply in sufficient, even coating thickness to ensure full opacity. Cure with adequate UV energy (typically 300-500 mJ/cm²) to achieve complete polymerization and prevent under-curing or poor adhesion. Surface pretreatment (e.g., corona treatment) may be required for low-energy substrates to enhance bonding.
