RIASORB UV-292 HALS hindered amine light stabilizer

Low molecular weight hindered amine-based liquid light stabilizer

RIASORB UV-292 is a high-performance light stabilizer that excels in volatility resistance and heat resistance. As it is a liquid product, it is primarily used in liquid products such as paints. Its main applications include exterior wall and exterior coatings, automotive paints, and waterproof coatings. The recommended addition amount varies depending on the performance requirements of each company, but it is generally 0.1-2.0 wt%. Additionally, there is a synergistic effect when used in combination with ultraviolet absorbers such as RIASORB UV-1130. However, caution is needed as thiol ether-based antioxidants may have antagonistic effects. Furthermore, Rianlon has a strong supply chain for HALS products due to its acquisition of Kaiya Chemical through M&A in 2018. Since we manufacture from upstream raw materials, we are confident in our supply stability and competitiveness in the market. *Kaiya Chemical = Manufacturer of HALS intermediates We can propose additives tailored to your applications, so please feel free to contact us! ■Application: Automotive coatings and paints Industrial coatings and paints

RIASORB UV-770 HALS hindered amine light stabilizer

General-purpose low molecular weight hindered amine-based light stabilizer

RIASORB UV-770 is used in many polymers such as PP, PE, TPO, EPDM, PS, ABS, TPU, PA, and POM. Due to the minimal difference in effects based on thickness, it is widely used from films to molded products. By using it in conjunction with antioxidants, thermal stability can be enhanced, and a synergistic effect can be expected when used with ultraviolet absorbers. Caution is necessary when used in combination with thioether-based compounds such as DSTP and DLTP due to antagonistic effects. Due to its basic nature, if there are concerns about the acidity of the material itself, we recommend UV-622. If liquid HALS is available, UV-123 is also recommended. ■Application: Polyolefins EPDM ABS PU PA POM

RIASORB UV-123 HALS hindered amine light stabilizer

Low molecular weight, low alkalinity hindered amine-based liquid light stabilizer. It is mainly used in automotive paints, industrial paints, and decorative/wood coatings!

RIASORB UV-123 is a liquid HALS with an amino ether group, primarily used for coatings. A characteristic of this structure is its low basicity, which minimizes reactions with acidic components in coatings. This product is mainly used in automotive coatings, industrial coatings, and decorative/wood coatings. In automotive coatings, it significantly improves weather resistance when used in combination with UV absorbers such as RIASORB UV-1130 and UV-928, effectively contributing to discoloration prevention, gloss retention, and interlayer adhesion prevention. Additionally, Rianlon has a strong supply chain for HALS products due to its acquisition of Kaiya Chemical through M&A in 2018. Since manufacturing is done from upstream raw materials, we are confident in our supply stability and competitiveness in the market. *Kaiya Chemical = Manufacturer of HALS intermediates HALS products are confidently recommended by Rianlon Japan as well.

RIASORB UV-622 HALS Low Basic Light Stabilizer

Low salt, high molecular weight hindered amine light stabilizer

RIASORB UV-622 is a low-basicity N-R type HALS. HALS protects polymers from UV-induced photodegradation and thermal decomposition caused by long-term heat by capturing radicals generated within the polymer. RIASORB UV-622 has high compatibility with polymers, excellent volatility resistance, migration resistance, and extraction resistance, as well as outstanding thermal stability during processing. RIASORB UV-622 has a low melting point and is used in PP, PE, PS, unsaturated polyester, PMMA, PVC, and elastomers. It interacts minimally with pigments and demonstrates high weather resistance in outdoor applications when combined with phenolic antioxidants, phosphorous antioxidants, and HALS or UV absorbers of different molecular weights. UV-622 has an alkyl group coordinated to the piperidine ring, resulting in a lower basicity structure compared to N-H types like UV-770. If there are concerns about the acidity of the polymer or formulation, the use of UV-622 is recommended. Caution is necessary when used in combination with thioether-based antioxidants such as DSTP and DLTP, as they may have antagonistic effects.
