Properties:
Very good heat stability,
Low surface tension,
High compressibility,
Excellent weathering resistance,
Good oxidation resistance,
Low freezing point,
Less change in viscosity as a function of temperature than non-silicone oils,
Good resistance to high and prolonged shear forces,
Low heat of combustion,
Limited combustion.
Storage and shelf life:
When stored in its original unopened packaging at a temperature of between -20 and +30 ºC, IOTA PDMS 47V3 - 47V10 may be stored for up to 36 months from its date of manufacture (expiry date). Comply with the storage instructions and expiry date marked on the packaging.
Exceed the date, IOTA Silicones no longer guarantees that the product meets the sales specifications.
