The key features and benefits of PowerSorb™460 contains:
- Hydroxyphenyl-triazine with high absorbance in the UV-B region;
- Low color, low migration;
- Minimal interaction with metal catalysts and amine crosslinkers;
- Excellent photo-permanence.
PowerSorb™ 400 is a liquid hydroxyphenyl-triazine UV absorber that provides excellent performance in coatings due to:
- very high thermal stability and performance for coatings exposed to high bake cycles and/or extreme environmental conditions;
- hydroxy functionality to minimize migration;
- high photo-stability for long life performance;
- high concentration for maximum efficiency.
PowerSorb™ 400 has been developed as an interaction-free UV absorber for use in amine and/or metal catalyzed coating systems and coatings applied on base-coats or substrates containing such catalysts.
PowerSorb™ 400 is recommended for solventborne automotive OEM and refinish coating systems, UV cured coatings, and industrial coatings where long life performance is essential. In addition, PowerSorb™ 400 is ideal for exterior construction coatings (roofing, etc.), construction adhesives, and sealants.
The protective effects of PowerSorb™ 400 can be enhanced when used in combinations with a HALS chemical such as PowerSorb™ 123, PowerNox™ 1425 or PowerSorb™ 292. These combinations improve the durability of clear coats by retarding gloss reduction, delamination, cracking, and blistering.
The amount of PowerSorb™ 400 required for optimum performance should be determined in laboratory trials covering a concentration range.
Recommend Concentrations:
1 – 3% PowerSorb™ 400 + 0.5 – 2.0 % PowerSorb™ 123, PowerStab™ 152 or PowerStab™ 292
Appearance | Light yellow viscous liquid |
Density (g/cm³) | 1.07 |
Miscible with most customary organic solvents; practically immiscible with water.
