ELASTOSIL® LR 3842/60 A/B
- Chemical Family
- Silicones
ELASTOSIL® LR 3842/60 A/B is a low-oil-bleeding liquid silicone rubber from the ELASTOSIL® LR 3842 series. It is a paste-like, easily pigmentable, two-component product with short curing times. Shortly after the curing process, a thin oil film with lubricating properties forms on the surface of the vulcanizates. The vulcanizates are opaque and exhibit good mechanical and electrical properties, as well as very low compression sets.
