ELASTOSIL® A316 is a free flowable, solvent-based RTV-1 silicone dispersion. It cures at room temperature or elevated temperature by reaction with air humidity to a flexible silicone coating. During cure it splits off an organic amine.


  • ready-to-use, one-component material
  • short skin-over time
  • solvent based
  • good adhesion on different substrates
  • excellent heat resistance

ELASTOSIL® A316 can be applied by dipping, spraying, brushing or coating. Thinner coatings can be obtained by addition of solvents (e.g. toluene, white spirit), thicker coatings can be realised by multiple step coating.

ELASTOSIL® A316 contains about 40% of solvent (b.w.) therefore suitable equipment has to be used and precaution measures due to the solvent vapours have to be taken. A volume shrinkage of slightly above 40% has to be considered.

ELASTOSIL® A316 is a one-part room temperature curing coating therefore the curing rate depends on temperature and on atmospheric humidity. The curing rate can be accelerated by heat exposure or exposure to carbon dioxide concentration above 1% p.b.v.

Uncured or partially cured silicone can be removed by help of organic solvents such as alipatic or aromatic hydrocarboncleaning should take place before the rubber is fully cured. Once completely cured, only mechanical removal supported by prior solvent swell is possible. Swelling can be accelerated by elevated temperature.

We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive instructions are given in our leaflet "ELASTOSIL® RTV-1 Silicone Rubber".

- Protective coating against moisture and enviromental influence

- thin film coating for sealing applications


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.
