ELASTOSIL® LR 3076/70 A/B

Self-adhesive liquid silicone rubbers of the ELASTOSIL® LR 3076 series are paste-like, easily-pigmentable two-component compounds with extremely short curing times and improved oil resistance. Their vulcanizates are noted for good mechanical and electrical properties.



Properties

ELASTOSIL® LR 3076 series are primerless, selfbonding grades that adhere to various plastic substrates (e. g. PA, PBT) and metals, but not in the mold. The bonding is improved by a subsequent heat treatment process (e. g. one hour at 100 °C) or by a longer storing at room temperature. Because of the individual surface properties each substrate must be tested before mass production. For further information on tested material combinations please refer to the corresponding adhesion tables which are available upon request from the responsible sales manager. The cured rubbers are of beige color and show excellent oil resistance.

Storage

Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
