Q1: What is the primary function of a UV barrier coating?
A: It serves as a protective isolating layer that prevents interaction between the substrate and subsequent materials—such as inks, adhesives, or environmental contaminants. This ensures surface integrity, chemical resistance, and functional separation in multi-layer applications.

Q2: In which applications is a barrier coating most necessary?
A: It is essential in electronics (circuit board masking), specialty packaging (grease/moisture barriers), industrial labels (chemical exposure), and printed products requiring interlayer separation to avoid ink migration, adhesive interference, or substrate degradation.

Q3: Does the barrier property affect adhesion or flexibility of the coating?
A: No. The coating is engineered to maintain strong adhesion to various substrates while offering sufficient flexibility to withstand bending, folding, or thermal expansion without cracking or delamination. Its barrier performance is achieved without compromising mechanical properties.
