ELASTOSIL AUX G 3243 solvent-based mixture of siloxanes and reactive silanes used as adhesion promoter for silicone rubbers.

ELASTOSIL AUX G 3243 is a solution of a siloxanes and reactive silanes in organic solvents. It is used to pretreat metallic, ceramic, glass or other polymeric substrate surfaces to enable excellent adhesion towards subsequently vulcanized ELASTOSIL R solid silicone elastomers (HCR/HTV, peroxide curing).

After the solvents have evaporated, a rigid film of silicone resin is formed on exposure to atmospheric humidity. The primer film adheres firmly to a large variety of substrates and serves as adhesion promoter for subsequently applied silicone rubbers.

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.
