Omschrijving
Evonik INFINAM® RG 2000 L
INFINAM® RG 2000 L is a photo-resin for the demanding eyewear industry. The clear liquid formulation cures quickly and is easy to process. A low yellowing index - even after prolonged UV irradiation –make the high-performance material attractive for additively manufactured eyewear frames.
For commercial users only!
Unique Properties:
- High impact resistance
- High temperature resistance
- High mechanical resistance
- Very good processability
Applications:
The low yellowing index - even after prolonged UV irradiation makes it also suitable for applications such as microfluidic reactors or transparent high-end prototypes for observing the inner workings of complex assemblies. The excellent light transmission of INFINAM® RG 2000 L also opens up further applications such as lenses, light guides and illumination covers.
