ELASTOSIL® SOLAR 1101

1 of 230 products in this brand
ELASTOSIL® SOLAR 1101 is a one-part, non-slump silicone adhesive that is solvent-free and non-corrosive. Upon exposure to air moisture, the adhesive cures at room temperature to produce a permanently flexible silicone rubber possessing exceptional mechanical properties. Fully cured ELASTOSIL® SOLAR 1101 exhibits exceptional long-term stability against weathering, moisture, and UV radiation, while being able to withstand constant exposure to ever-changing climatic conditions, UV radiation, and temperatures as high as 180°C (356°F) without damage.

Application Details
  • General-purpose adhesive for the solar energy industry
  • Typical fields of application: frame sealing, bonding of junction boxes, fixation of backrails and mirror elements.

Processing

  • ELASTOSIL® SOLAR 1101 is a ready-to-use, one-part silicone rubber which starts curing when exposed to air moisture.
  • As RTV-1 silicones require humidity for curing, free access of air moisture to the silicone rubber is essential. Additionally, the vulcanization time of ELASTOSIL® SOLAR 1101 can be greatly reduced by increasing the level of air's relative humidity.
  • Please note that, unlike the initial skin formation, the total curing rate of RTV-1 silicones is limited by moisture's diffusion speed in silicone rubber. Since increasing the curing temperature has just a minor effect both on the skin formation time and the curing speed, ELASTOSIL® SOLAR 1101 typically is vulcanized at room temperature.
  • After completion of the vulcanization the silicone elastomer may continuously be exposed to constantly changing climatic conditions, UV radiation and high temperature without damage. Cured ELASTOSIL® SOLAR 1101 usually shows good primerless adhesion to many substrates, in particular to those which are common for the PV industry (glass, anodized aluminum, Tedlar® films, pre-treated PVF and PVDF 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 rubber is fully vulcanized. Cured silicone needs to be rubbed off or removed mechanically, if necessary in combination with a swelling agent (solvent) or a chemical silicone remover.

Safety & Health

Safety Note
  • While curing ELASTOSIL® SOLAR 1101 releases a total of approx. 3.5 % by weight of alcohol. These vapors should not be inhaled for long periods or in high concentration. Work areas should therefore be well ventilated.
  • Contact of the uncured silicone rubber with eyes and mucous membranes must be avoided as this can cause irritation. If, despite all protective measures, uncured silicone rubber comes into contact with the skin or eyes, irrigate the affected area immediately with copious amounts of water for several minutes. If the irritation continues, immediately seek medical advice.
