Technical Datasheet | Supplied by Kuraray
DPNG by Kuraray is a nitrogen- & sulfur-free antioxidant and catalyst/accelerator. It possesses low toxicity and high stability. It is synthesized chemically from petrochemicals. This liquid oxygen scavenger solves poor curing problem. It solves not only oxygen inhibition of radical polymerization especially UV curing, it also solves resin deterioration like resin yellowing by oxidation. It also works without catalysts. It avoids metal oxidation and absorbs oxygen. DPNG is used for air-drying unsaturated polyester paints, UV ink and coatings.
