ELASTOSIL® R 3113 A/B is a two-component, heat curing silicone rubber adhesive. ELASTOSIL® R 3113 A/B is used for fast bonding of cured silicone rubber to cured silicone rubber. It is suitable for bonding of large, flat shapes.

Before applying the adhesive the surfaces of the substrate should be cleaned with a non-polar solvent, e.g. chemically pure acetone or white spirit.

After thorough mixing of component A with 1% of component B the mixture should be applied in a thin layer. The parts should be fixed with low pressure to avoid squeezing out the adhesive. Curing of the adhesive takes place at 130°C.
The curing process of the adhesive is finished after approx. 30 seconds at 130°C.

Cycle time is mainly depending on the heat transfer and volume of the substrate.
Adhesion can be further improved by post curing, e.g. at 200°C for 4h.


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.
