ELASTOSIL® SOLAR 1200

1 of 230 products in this brand
ELASTOSIL® SOLAR 1200 is a non-slump, condensation-curing RTV-2 silicone adhesive designed for the solar industry. When used with a curing agent from the WACKER® Catalyst T 77 series, it forms a self-bonding and durable silicone rubber. Cured ELASTOSIL® SOLAR 1200 offers excellent long-term stability against weathering, moisture, and UV light. The silicone elastomer can endure constantly changing climatic conditions, UV radiation, and temperatures as high as 180°C (356°F) without damage.

Processing

Mixing and curing:

  • ELASTOSIL® SOLAR 1200 is processed in combination with a curing agent, such as WACKER® Catalyst T 77 or WACKER ® Catalyst T 77 PLUS. Prior to application the two compounds should be thoroughly mixed, either manually or by automatic metering lines equipped with static or dynamic mixing devices.
  • The recommended mixing ratio is 10:1 by weight. Potlife and curing speed can be modified within limits by adjusting the ratio of base compound (ELASTOSIL® SOLAR 1200) to curing agent (WACKER® Catalyst T 77 or WACKER® Catalyst T 77 PLUS). Varying the mixing ratio between 8:1 and 12: usually has a small effect on the properties of the cured rubber. However, if the mixing ratio differs substantially from the recommended scope, preliminary tests should be carried out to check the cured material’s suitability.
  • Moreover Curing speed can be slightly accelerated by raising the temperature. Heating, however, must not exceed 60 °C before curing is completed. After completion of the vulcanization process the product may continuously be exposed to constantly changing climatic conditions, UV radiation and high temperature without damage.
  • Cured ELASTOSIL® SOLAR 1200 usually shows good primerless adhesion to many substrates, in particular to those materials which are typical of the solar industry (glass, anodized aluminum, Tedlar® films, PVF, PVDF, PPO, PPS etc.).

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 needs to be removed mechanically, if necessary in combination with a swelling agent (solvent).
