High oil-bleeding liquid silicone rubbers of the ELASTOSIL® LR 3856
series are paste-like, easily pigmentable two-component products with short curing times and very good demoldability (high hot tear resistance).
Shortly after curing a thin oil film with lubricating properties forms
on the surface. The vulcanizates are opaque, have very good mechanical and electrical properties, excellent cut resistance, and low compression set without post-cure.
