Aron Powder® Product Series
The highly weather-resistant Aron Powder® Series is used for powder coating most automotive windshield wipers worldwide. The highly insulating Aron Powder® coating series is suitable for precision components requiring electrical insulation.
Product Characteristics
| Low-Temperature-Curing Series | Epoxy types cure at 120°C, and epoxy-polyester types cure at 150°C. |
| Highly Weather-Resistant Series | In addition to excellent resistance to continuous UV exposure in accelerated weathering tests, these products offer excellent impact resistance and salt-spray resistance. |
| Matte Series | Extremely low light reflection after coating enables a completely matte finish. |
| Insulating Series | For products requiring high dimensional coating accuracy, these materials uniformly coat small components and corners or edges and provide highly reliable insulation. |
