ELASTOSIL® SOLAR 2202 A/B

ELASTOSIL® SOLAR 2202 A/B is a pourable, addition-curing, RTV-2 silicone rubber for potting, lamination and encapsulation purposes. The product vulcanizes at room temperature to yield a very soft silicone gel. 

 

Cured ELASTOSIL® SOLAR 2202 A/B shows a pronounced inherent tack and long-term stability against weathering, moisture and sunlight. The soft silicone gel may continously be exposed to constantly changing climatic conditions, UV radiation and temperatures as high as 160 °C (320 °F) without damage.

Important!
Only A and B components with the same batch number should be processed together!

 

Surface preparation:

All surfaces must be clean and free of contaminants that will inhibit the cure of ELASTOSIL® SOLAR 2202 A/B. 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.

 

Mixing:

Caution! Component B of ELASTOSIL® SOLAR 2202 A/B contains the platinum catalyst, component A the crosslinker. Since even traces of platinum catalyst may cause gelling of component A, all tools (e.g. spatula, stirrers, mixing cups etc.) used for handling either component B or the A/B mix must not come into contact with component A by mistake.

 

The two components should be thoroughly mixed at a 1 : 1 ratio by weight or volume, either manually or by automatic metering lines equipped with static or dynamic mixing devices.

 

Material application:

To eliminate any air introduced during dispensing or trapped under components or devices a vacuum encapsulation is recommended. Alternatively, component A and B can be deaerated individually prior to use to remove absorbed air; applying a vacuum of 25-50 mbar for 10-15 min is recommended.

 

Curing:

The curing time of addition-curing silicone rubber is highly dependent on temperature and both the size and the heat sink properties of the components being potted. ELASTOSIL® SOLAR 2202 A/B cures both at room temperature and under heat. General information about pot life, typical curing temperatures and resulting curing times are given in table "Properties Catalyzed A+B".

 

The reactivity of ELASTOSIL® SOLAR 2202 A/B can be adjusted within wide limits by adding WACKER® Catalyst EP or WACKER® Inhibitor PT 88 to suit the processing requirements of the particular application. WACKER® Catalyst EP increases reactivity, i. e. pot life and curing time are reduced. WACKER® Inhibitor PT 88 is a pot life extender and thus prolongs pot life and curing time.

 

Modifying softness:

If the gel is too soft and tacky, reducing the amount of component B results in a harder, less tacky vulcanizate. A tough gel is obtained with a mixing ratio for A:B of 1.25:1, while a mixing ratio of 1.5:1 yields a very soft rubber. Please note: for logistical reasons however, we can only accept orders in a mixing ratio of A:B = 1:1.

 

Pigmentation:

ELASTOSIL® SOLAR 2202 A/B is colourless, transparent and crystal clear. If necessary, the product can be pigmented by adding up to 2 wt. % of ELASTOSIL® COLOR PASTE FL.

 

Detailed information about processing, modifying curing speed and pigmentation 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 gel can be rubbed off and removed mechanically, if necessary in combination with a swelling agent (solvent).

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.
