6. FAQ Frequently Asked Questions
Q1: What is MOQ? A: Minimum order quantity is 1 L for sample test; bulk‑order MOQ 1 barrel. Sample is available for press trial.
Q2: What is delivery lead‑time? A: Stock goods: ship within 3 working‑days after payment confirmed. Custom‑formula / OEM private‑label goods: 12‑16 working‑days.
Q3: What customization service do you provide? A: Adjust gloss level, modify viscosity for rotary‑screen, optimize hot‑stamping performance; OEM private‑label sticker & custom carton packing.
Q4: Logistics & shipping options? A: UV varnish belongs to chemical liquid goods. International courier: FedEx, TNT, DHL, UPS, EMS. Large‑volume bulk‑order choose sea‑freight or air‑freight. Payment terms: T/T, Western Union, Paypal.
Q5: Hot‑stamping foil cannot transfer cleanly after UV curing? A: Check: 1) UV over‑curing (excessive lamp power); 2) Varnish film thickness too thin; 3) Hot‑stamping temperature / pressure / speed mismatch; 4) Mismatched hot‑stamp foil grade. Adjust UV energy and hot‑stamp parameters accordingly.
Q6: Varnish surface is sticky after UV curing? A: Insufficient curing energy; increase UV lamp power or reduce machine running speed. Note full resistance property is achieved after 24‑h post‑curing.
Q7: Can I mix this varnish with other brand UV varnish? A: Not recommended. Different resin & photoinitiator systems may cause gelling, poor hot‑stamp performance. If mixing is unavoidable, run small‑scale lab test first.
