ELASTOSIL® LR 3846/20 A/B

Chemical Family
Silicones

ELASTOSIL® LR 3846/20 A/B is a considerable oil-bleeding, liquid silicone rubber of the ELASTOSIL® LR 3846 series. It is a paste-like, readily pigmentable, two-component product with a short curing time. Shortly after the curing process, a slight, thin oil film with lubricating properties forms on the surface of the vulcanizates. The vulcanizates are opaque, have good mechanical and electrical properties, and have very low compression sets.
