Additive or reactive: DAINSORB® ultraviolet absorber is unlike any other in the world

Ultraviolet absorbers

Industrial material film coverings, automobile paints, building materials, electronic materials, solar battery sheets, and many products essential to our lifestyles, are constantly exposed to ultraviolet rays, causing fading colors, cracking, and malfunction. DAINSORB® is a benzotriazole ultraviolet absorber with superior absorption capabilities, and comes in two varieties.

Prevents discoloration! Meta-position substituted ultraviolet absorber
The DAINSORB® series of additives offers 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. The DAINSORB® series is tailored to meet the wide range of our customers’ ultraviolet absorbing requirements.
No more bleed-out! Reactive ultraviolet absorber
Reactive ultraviolet absorbers make ideal ultraviolet absorbing unit polymers through a process of synthesis by co-polymerizing with the monomers that comprise high-polymer materials. This resolves a long-standing weakness of ultraviolet absorbing additives: bleed-out. Reactive ultraviolet absorbers offer weather resistance for 10+ years and are suitable for use in automobiles and building materials.
