Chinox® TP-80 is a phenol free, liquid Anti-oxidant with UV stabilizer performance designed specifically for polyurethane. Chinox® TP-80 is a phenol free, liquid antioxidant with UV stabilizer performance designed specifically for the protection of polymers against the damage of UV light radiation and offering heat stability during processing. Chinox® TP-80 has good solvent solubility and better resin compatibility.
Chinox® TP-80 is suitable for the protection of polymers due to its excellent solubility in resin and its non-yellowing property during processing stage. Therefore, Chinox® TP-80 has been widely using in the following areas: 1. PU foam. 2. PU leather and film. 3. PU coating. 4. PU plate. 5. Epoxy resin
Chinox® 2430 is a liquid Anti-oxidant designed specifically for the protection of polymers from the damage during heat processing. Chinox® 2430 is a liquid antioxidant with designed specifically for the protection of polymers from the damage of heat processing. Chinox® 2430 has good solvent solubility, better resin compatibility and excellent anti-scorching in PU foam applications.
Chinox® 2430 is most suitable for the protection of polymers due to its excellent compatibility with resin and its non-yellowing property during baking stage. Chinox® 2430 has been widely used in PU foam. A percentage of 0.3% -0.5 % of Chinox® 2430 is recommended for protection.
4. Chitex® AO-20 is an Anti-oxidant specifically designed for the protection of Nylon and other textile. Chitex® AO-20 is a heat stabilizer designed specifically for the protection of Nylon and other textile. Chitex® AO-20 can enhance the heat stability of Nylon and prolong the endurance of textile.
Chitex® AO-20 can be used in: 1. Latex. Dosage: 1-2%.
5. Chisorb® TPU is a Stabilizer specifically designed for the protection of TPU from UV light, oxidation and Nox. Chisorb® TPU is a stabilizer designed specifically for the protection of thermoplastic polyurethane from the damage of UV light, oxygen and NOx. Chisorb® TPU has better resin compatibility, is less volatile, and provides a degree of stabilization that is significant better than other UV absorbers, antioxidants which are commercially available in the market.
Chisorb® TPU is most suitable for the protection of thermoplastic polyurethane due to its synergist performance. A percentage of 0.5 % - 2.0 % of Chisorb® TPU is recommended for protection.
6. Doublemer® 188 is a high functional Aromatic Urethane Acrylate oligomer which exhibits excellent hardness and solvent resistance. UV/EB cured products based on DOUBLEMER® 188 are characterized by the following performance properties:
The actual properties of UV/EB cured products also depend on the selection of the other formulation components such as reactive diluents, additives, and photoinitiators.
7. High performance Antioxidant, CHINOX® AO-602L for PVC polymercerization as chain stopper and anti-oxidant.
Dosage: 200 ppm in PVC latex when reaction completion 85-90% All the value is initial color figure of PVC latex after compounding CHINOX® AO-602L: Butylated phenolic antioxidant, designed for water borne system resin such like PVC polymerization, SBR/MBS latex, ABS emulsion polymerization, water borne PU. It protects from oxidation, which causes yellowing, brittle, and cracking. CHINOX® 245DW Ethylenebis(oxyethylene)bis-(3-(5-tert-butyl-4-hydroxy-m-tolyl)-propionate) CAS:36443-68-2
8. Outstanding UV absorber,CHISORB® UV-9000 series, for polyurethane resistance to yellowing from heat, UV light, NOx.
9. Water soluble benzotriazole, CHISORB® 5228S, improve lightfastness of nylon, wool and leather.
Test method
• Chisorb® 5228S is a high performance Water soluble UVA • Chisorb® is a trademark of Double Bond Chemical
10. Chisorb® EPL, an unique UV absorber for epoxy resin. Epoxy resin has many good performances such as good resistance to water, chemical, acid and so on, but weatherability is always a big disadvantage to epoxy resin. Most UV absorbers and light stabilizers can not help this phenomenon excepting Double Bond’s Chisorb EPL.
11. Outstanding liquid UV absorber, Chisorb® SUV to resist yellowing from UV light used in PU foam and coating.
12. Reactable light stabilizer (HALS), Chisorb® 582L and Chisorb® 587P launched to the market. Market is always looking for non-migration and long-term performance light stabilizers. Chisorb 582L and Chisorb 587P are created for this expectation. One molecular perfectly consists of one Methacrylate and one HALS function. Its Methacrylate could react with most double bond molecular such as acrylate and unsaturated polyester by free radical polymerization initiated by peroxide or UV Initiator.
13. Long term performance UV absorber, Chisorb® 5431, commercially launched to the market. High molecular, low migration, high performance with good solubility in coatings or plastics, always a challenge to UV absorber supplier. Double Bond’s Chisorb 5431 is exactly coped with those requirements. The long alkyl group has good solubility in most matrixes, and benzotriazole dimer plays as bulky active site with low migration possibility.
14. Chitex® NF, water soluble optical brightener designed for water borne application. Water borne coating is more and more popular in most applications. Water soluble additives have always been requested for this trend. Chitex NF is created by this request to enhance whiteness for most water borne applications.
15. Chitex® RF, dispersed optical brightener in UV monomer, used in UV application. Optical brightener is commonly used in OPV and clear lacquer to enhance whiteness. However, limited solubility of optical brightener in monomer, solvent always cause difficult handling. Chitex RF is a pre-dispersed optical brightener master batch with characters of easy flow, easy use, with dosing of 200-500ppm could enhance whiteness for most UV formulation.
