Q1: Why is polypropylene (PP) typically challenging to coat, and how does this product address it?
A: PP has an extremely low surface energy and non-polar chemical structure, making adhesion difficult for most coatings. This product incorporates specialized adhesion promoters and modified resins that bond directly to PP, eliminating the need for primers or surface pretreatment.

Q2: What are the main advantages of a direct-to-substrate UV coating for PP applications?
A: It simplifies production by removing primer application and drying steps, reduces material costs, and shortens processing time. The coating offers immediate durability after UV curing, including resistance to scratches, chemicals, and abrasion, while providing a consistent matte finish.

Q3: Are there limitations on the types of PP substrates or end-use conditions for this coating?
A: It performs best on injection-molded, extruded, or corona-treated PP surfaces. Heavily textured or contaminated surfaces may require cleaning or testing. While suitable for indoor and moderate outdoor use, extended UV exposure or extreme chemical contact should be evaluated case-by-case.
