ELASTOSIL® RT 706

ELASTOSIL® RT 706 is a self-levelling, slightly thixotropic, one-part heat-curing silicone for potting and coating applications.

 

Cured ELASTOSIL® RT 706 shows very good adhesion to many substrates and long-term stability against weathering, moisture and UV light. The cured silicone rubber may continuously be exposed to constantly changing climatic conditions, UV radiation and temperatures as high as 230 °C (446 °F) without damage.

  • Multipurpose potting and coating grade
  • Typical fields of application: household appliances, automotive and mechanical engineering.

Preparation:

All surfaces must be clean and free of contaminants that will inhibit the cure of ELASTOSIL® RT 706. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds. If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.

 

To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended. Alternatively, ELASTOSIL® RT 706 can be de-aerated prior to use; applying a vacuum of 25-50 mbar for 10-15 min is recommended

 

Curing:

ELASTOSIL® RT 706 is a one-part heat-curing silicone, the curing time of which is highly dependent on temperature and on both the size and the heat sink properties of the components being potted. ELASTOSIL® RT 706 is usually cured between 140 °C and 200 °C in order to secure a quick build-up of adhesion to the respective substrate. Typical curing temperatures and resulting curing times are given in adjacent table.

 

Detailed information about processing one-part heat-curing silicones is given in our brochure “ROOM TEMPERATURE VULCANIZING (RTV) SILICONES - MATERIAL AND PROCESSING GUIDELINES”. We recommend running preliminary tests to optimize conditions for the particular application

 

Removal:

If removal of the silicone from machines or dispensing equipment is necessary, white spirit or similar nonpolar solvents are recommended. However, cleaning ideally should take place before the silicone is fully vulcanized. Cured silicone rubber needs to be rubbed off or removed mechanically, if necessary in combination with a swelling agent (solvent) or a chemical silicone remover.

 

 

储存

Store in a dry and cool place.

 

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.
