Q1: How does UV curing benefit the lamination process compared to traditional adhesives?
A: UV curing enables instant bonding on demand, eliminating drying delays and solvent emissions. It allows for precise control of bonding time and strength, reduces energy consumption, and minimizes substrate exposure to heat or moisture, making it ideal for heat-sensitive materials and high-speed production lines.
Q2: What types of substrates and applications is this adhesive best suited for?
A: It is ideal for bonding films (PET, BOPP, PVC), foils, paperboards, and rigid plastics in applications such as flexible packaging, label lamination, decorative panels, security films, and industrial composites. Surface compatibility should be verified to ensure optimal adhesion.
Q3: Are there specific application or curing requirements to achieve optimal bond strength?
A: Yes. Apply a uniform coating thickness and ensure full exposure to adequate UV intensity (typically 200-600 mJ/cm²) for complete curing. Surface preparation (e.g., cleaning, corona treatment) may be needed for low-energy substrates. Testing under production conditions is recommended to optimize pressure, speed, and lamp settings.
