ELASTOSIL® SOLAR 1101

ELASTOSIL® SOLAR 1101 is a non-slump, one-part silicone adhesive. It is sovent-free and non-corrosive. When exposed to air moisture ELASTOSIL® SOLAR 1101 cures at room temperature to yield a permanently flexible silicone rubber with very good mechanical properties.

 

Fully cured ELASTOSIL® SOLAR 1101 shows long term stability against weathering, moisture and UV radiation. The silicone elastomer may continously be exposed to constantly changing climatic conditions, UV radiation and temperature as high as 180 °C (356 °F) without damage.

ELASTOSIL® SOLAR 1101 is a ready-to-use, one-part silicone rubber which starts curing when exposed to air moisture. Typical curing characteristics are given in the table "Properties Uncured".

 

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 aluminium, Tedlar® films, pre-treated PVF and PVDF etc.).

 

Detailed information about the processing of RTV-1 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 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.
 

Storage

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.
