ELASTOSIL® E303 TRANSLUZENT
ELASTOSIL® E303 TRANSLUZENT is an acetoxy-cure, 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.
- ready-to-use, one-component material
- solvent based
- excellent primerless adhesion to many substrates
- Protective coating against moisture and environmental influence
- Thin film coating for sealing applications
Typical application is selective coating of heat exchangers (automotive radiators).
ELASTOSIL® E303 TRANSLUZENT can be applied by
Thinner coatings can be obtained by addition of solvents (e.g. toluene, white spirit), thicker coatings can be realised by multiple step coating.
ELASTOSIL® E303 TRANSLUZENT contains about 60% of solvent 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 50% has to be considered.
ELASTOSIL® E303 TRANSLUZENT 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.
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. In thin films, Wacker Silicone Remover S8 is suited as well.
We recommend running preliminary tests to optimize conditions for the particular application.

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.
