The DAINSORB® Series helps reduce the ultraviolet radiation-induced deterioration of plastics.
Many plastic products, indispensable for our daily lives, are constantly at risk of different types of deterioration, including discoloring, cracking, and breakages as a result of exposure to ultraviolet radiation. The DAINSORB® series of products include benzotriazole-based ultraviolet absorbers for better absorption. Two types are available. Reactive ultraviolet absorbers have unique features not found at any other company and are being used for more and more applications.
Reactive ultraviolet absorbers
guarantee 10+ years’
DAINSORB® fundamentally solves ultraviolet absorbers’ bleed-out issue, and provides long weather resistance of 10+ years. It also offers strong support to solve problems with plastic parts, including automobile window glass resin glazing and coating agents, next-generation organic EL displays, interior and exterior building material sheets and panels, solar cell backsheets, and more.
For automobile coating agents requiring long-lasting weather resistance, as well as interior/exterior building material sheets.
No more eyeglass lens discoloration:
We’ve supplied more ultraviolet absorbers for plastic eyeglass lenses than anyone in the world. They offer superior absorption, particularly of UV-A waves (315 to 400 nm), and can even limit absorption of the visible range (400 nm and beyond), thus preventing discoloration and maintaining your product’s external appearance.
