For UV curing promotion, resin degradation suppression, and metal oxidation prevention. A new material that absorbs and decomposes oxygen independently from organic substances! [Oxygen absorption test and application examples are currently available.]

We have developed a new material, "Diprenyl Glycerin Ether (DPNG)," which absorbs and decomposes oxygen that adversely affects manufacturing processes and product quality when in contact with organic substances alone. It is a colorless, transparent liquid with no odor, and does not contain nitrogen or sulfur compounds. Additionally, being in liquid form allows for easy mixing with various materials. 【Features】 ■ UV curing promotion ■ Prevention of resin oxidation (such as polyurethane and epoxy resins) ■ Prevention of pigment and other functional material oxidation ■ Prevention of metal oxidation ■ Colorless, transparent liquid, odorless ■ Does not contain nitrogen or sulfur compounds ■ No metal catalysts required ■ Low toxicity ★ Currently, we are publishing data on the results of oxygen absorption tests for this product, along with various application examples. → For more details, please refer to the PDF document or feel free to contact us.
