Silicone Addition Clear 0 Supersoft Set
The Silicones Clear 0 Supersoft Set is a two component Poly-addition-silicone which cures at room temperature. After mixture, the Silicones have good liquid qualities and are crystal clear. In time the hardened silicones will become a little yellowish, but will not lose its transparency.
Due the low shrinkage and clear properties this silicones are ideal for encapsulating or potting of electronics and optical elements. The silicone will result in a stiff but soft gel, with a tacky feel.
These silicones are not really suited for molds as the tensile and tear strength are too low.
- Low shrinkage <0,1%.
- Very good fluidity
- Self deaerating
- Well suited for potting
- Soft but elastic gel
Technical Data
- Mixing ratio in weight: A:B = 1:1
- Pot life at 23°C: 50 minutes
- De-mould time at 23°C: 3 hours
- Viscosity at 23°C: 1500-2500 cSt
- Color: clear
- Hardness: shore A 0
Note: Pot life / de-mould time is highly dependent on temperature! At a higher temperature, the processing time and de-mould time are shorter.
Processing
The Silicone A- and B-component can easily be mixed by hand or by machine. Mix the A and B component carefully and in the indicated ratio (100 parts A and 100 parts B by weight). Process the mixture within the pot life and demould only after it is cured complete. Alternatively, you can speed up the curing process by placing the whole mould in an oven. Please note that air bubbles will then have less time to escape the casting.
Extra information
Trapping of air bubbles can be prevented best by placing the silicone under vacuum immediately after mixing. To prevent air bubbles, stir the A and B component well but slowly without stirring in air. We advise to use a figure of 8 motion. If you want to reduce the Shore (hardness), you can add silicone oil from the shop. Please note that oil does not bind to the silicone network and may over time bleed from the silicone.
If you do not want to pour the silicone spatula but you can add Silicone Thixo A (note: not Silicone Thixo C !!). You can also add Fumed Silica. You can silicone intense colors with silicon dye.
The silicon might obtain a very slight yellow hue when used at elevated temperatures (>80°C).
Please note: This is an addition curing silicone. This type of silicones may experience cure inhibition when coming into contact with sulfur, nitrogen, amino groups and metal salts. If you are not certain that the products you use (including gloves, spatulas and cups) contain these ingredients, please do a little test first! These components are often found in many latex gloves, some platicines, glues, lacquers, condensation curing silicones, silicone caulk, natural rubbers and 3D printing materials (mainly stereolithography).
Durability
Provided that the silicone is in a sealed container and stored cool and frost-free, the shelf life is at least 1 year.
Safety
If you use silicone frequently we advice the use of gloves and to work in a properly ventilated area. For safety information see the safety data sheet.
