ELASTOSIL® RT 80 Liquid Silicone Rubber

Characteristics

ELASTOSIL® RT 80 is a solvent dilute able, condensation-curing silicone rubber, ready-to-use product, that vulcanizes at room temperature and cures rapidly at high temperatures.

Special characteristics

• Flowable & Solvent dilute able
• Processing viscosity suitable for silk-screen printing
• Long term flexibility over a temperature range from -50 °C to +200 °C
• Good resistance to chemicals

Application
ELASTOSIL® RT 80 may be used for applications which require high or low temperature resistant flexible coating. 
A typical application in the automotive industry is silk-screen printing on selected areas of cylinder head gaskets.

Technical data

Processing

ELASTOSIL® RT 80, to be mixed thoroughly with Catalyst T 56 or 27 (Catalyst dose can be adjusted to control the curing speed), prior to dilution with solvent.

Small amounts can be mixed by hand or mechanically (e. g. power tool fitted with mixing blade) for at least 60 seconds.

Adhesion of ELASTOSIL® RT 80 depends on the amount of Catalyst and on curing conditions. Therefore, preliminary tests should be carried out to determine optimum formulation and cure conditions.

Storage

ELASTOSIL® RT 80 has a shelf life of at least 12 months when stored between 5 °C and 30 °C in the originally sealed container. The ‘Best use before end’ date of each batch appears 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.

Safety information

According to the latest findings, the condensation curing silicone rubber ELASTOSIL® RT 80 contains neither toxic or corrosive substances which would require special handling precautions. General hygiene regulations should be observed.
