2. Product Features
l The dosage of QR8006 is 1-3% of the total formula of powder coating, which can provide a minimum gloss of about 10%. This product is more suitable for powder coating with 10-40% gloss.
l The selectivity of resin is relatively small, and the formulation should be based on specific experimental results.
l Curing conditions were 190℃/15 min or 200℃/12 min
