ELASTOSIL® S 692 A/B
ELASTOSIL® S 692 A/B is a self leveling, electrically conductive, addition-curing two-component silicone rubber which can be cured at room temperature or at high temperatures. Due to its low outgassing rate and low temperature flexibility it is recommended especially for space applications.
ELASTOSIL® S 692 A/B has been developed and designed as ablative adhesive to avoid static electrical chargeing effects on solar generators for space applications such as satellites.

All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence.

Before use of ELASTOSIL® S 692 A/B the components must be thoroughly stirred.
The mixing ratio is 9 : 1.
At room temperature a mixture of A and B components has a pot life of 3 - 5 hours.
Various chemicals, e. g. sulphur, tin, nitrogen compounds such as amines, amides, azides etc., antiagers in plastics and rubbers etc., may cause a delay in vulcanisation or, in infavourable cases, prevent it. Therefore we recommend to test all materials with regard to their compatibility with ELASTOSIL® S 692 A/B.
To obtain adhesion to other materials (e. g. glass, aluminium, epoxide, polyester, polyimide), it is necessary to pretreat the surface with Primer G 790 or G 790 diluted 1 : 1 with an aliphatic hydrocarbon solvent (e. g. Isopar E or Esso AG, boiling range 110 - 140 °C at 1 bar).
