Oil-bleeding liquid silicone rubbers of the ELASTOSIL® LR 3844
series are paste-like, readily pigmentable two-component products 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, have good mechanical and electrical properties and very low compression sets.
