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.
- 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.
- 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.
As a trading company, Daiwa Fine Chemicals supplies a huge range of industries with raw materials for organic and inorganic industrial products. Daiwa Fine Chemicals (Laboratory) complements this by performing R&D into special products and organic chemical synthetics under request from customers.
- For instance, under contract from one client company, we synthesized various organic chemicals based on naphthaldehyde, and succeeded in creating a polymeric film base.
- Global competition demands that companies pursue research and development aggressively. As experts in fine chemicals, we at the Daiwa Kasei Group put our organic synthesis and microanalysis technologies to use by offering laboratory-scale organic synthesis under contract, thus providing customers a more efficient avenue for R&D.
