As a release agent.
Used purely or as a part of a compounded formula SiSiB® MF2010 provides a non-toxic, non-carbonizing mould release for silicone rubber, plastics and metal die-castings.
As an Anti-Foam agent.
Very small quantities of the fluid are very effective as a foam control agent, especially in non-aqueous systems.
As a mechanical fluid.
The very high viscosity-index, the thermal and chemical stability, shear-breakdown resistance and the rubber compatibility as well as the compressibility make this fluid outstanding for mechanical and hydraulic uses.
As a lubricant.
The lubricant silicone oil provides excellent lubricating properties for most plastic and elastomeric surfaces. Lubricity with metals depends upon the possible combinations such as P.T.F.E., MoS2 and other lubricity improvers.
In polishes and chemical specialties.
Silicone oil is used in most automobile and furniture polishes for its ease of application, high gloss with a minimum rubbing and durable water repellent film.
In electrical and electronic equipment.
Because of the excellent dielectric properties dimethicone oil is widely used as an insulating and damping fluid.
SiSiB® MF2010 is supplied in 190Kg steel drum or 950Kg IBC tote.
In the original unopened packaging, SiSiB® MF2010 fluid has a shelf life of 24 months when stored at ambient temperatures. The product does not freeze and there are no restrictions on storage.
