USES:  

 

RELEASE MATERIAL: Used alone or as part of a compounded formula, THE Fluid provides a non-carbonising mould release for rubber, plastics, and metal die castings. 

 

FOAM PREVENTIVE: Extremely small amounts of the fluid effectively control foam in many processing operations, especially in non-aqueous systems. 

 

MECHANICALFLUID: Excellent viscosity-temperature characteristics, thermal and chemical stability, shear-breakdown resistance, compressibility, and rubber compatibility make Fluid outstanding for mechanical/ hydraulic uses. Typical uses include hydrolic stabilisers, damping media.  

 

SURFACE-ACTIVE MATERIAL: Added to vinyl plastisols, THE Fluid improves the flow characteristics, de-aerates and lubricates the surface of the completed part.  

 

LUBRICANT: The fluid provides excellent lubrication for most plastic and elastomeric surfaces. Lubricity with metals depends upon the combination involved. Care should be taken to select suitable metals for pumps and other items with moving parts.

 

COSMETICS AND SKIN PREPARATIONS: THE Fluid is an important ingredient in hand creams, skin protectants, suntan lotions, and hair grooming aids because it forms a non-greasy, protective film which resists water and waterborne irritants, yet allows the skin to breathe. Literature is available that details the use of the fluid in cosmetics.  

 

POLISHES AND CHEMICAL SPECIALITIES: THE Fluid is used in most automobile and furniture polishes for its ease of application,high gloss with minimum rubbing, and a durable water-repellant film. It is also used in many other speciality formulations, including aerosol starches and fabric conditioners. Additional literature is available.  

 

ELECTRICAL/ELECTRONIC EQUIPMENT: With excellent dielectric properties, THE Fluid can be used for both insulating and damping applications.
