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.


  • resistant to very low temperatures
  • glass point: < - 100 °C (-148 °F)
  • particularly low volatile content
  • electrically conductive
  • admitted for space applications acc. to specification ESA ECSS-Q-70-01A
  • controlled production acc. to fixed prescription


Specific features of ELASTOSIL® S 692 A/B

  • Electrically conductive
  • Low volatile
  • Low-temperature flexible
  • UV stable

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).

Detailed processing instructions are given in our brochure “ROOM TEMPERATURE VULCANIZING (RTV) SILICONES - MATERIAL AND PROCESSING GUIDELINES


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.
