Details:

DY-201polydimethylsiloxane

（Dimethicone Silicone oil）

[Features]

-  DY-201 Dimethyl silicone oil, chemical nameis Polydimethylsiloxane, which formula is (CH3)3SiO[(CH3)2SiO]n-Si(CH3)3, thisproducts is a kind of transparent, colourless polydimethylsilixane liquid,available viscosities ranging from 12cps to 2000000cps.

-  Littlechange in physical properties over awide temperature span - arelatively flat viscosity-temperature slope, serviceability from  -50°Cup to 200°C.

-  Excellentwater repellency.

-  Gooddielectic properties over a wide rangeof temperatures frequencies.

-  Lowsurface tension - readily wets cleansurfaces to impart water repellencyrelease characteristics.

-   Viscositiesabove 10 mm2/s also exhibit heat stability,oxidation resistance, very low vapour pressures, high flash point.

-   Loworder of toxicity

-   Essentiallyodourless

-   Solublein a wide range of solvent

-   Non-greasynon-rancidifying

-   Viscosity-temperature cofficent issmall,high compression ratio.

Application

RELEASEMATERIAL: Used alone as part of a compounded formula,

DY-201 Fluid provides a non-carbonising mould release for rubber, plastics, metal die castings.

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

MECHANICALFLUID:Excellentviscosity-temperatureacteristics,

thermalchemical stability, shear-breakdown resistance, compressibility, rubber compatibility make DY-201 Fluid outstanding for mechanical/hydraulic uses. Typical uses include hydrolic stabilisers, damping media,heat transfer fluid etc.

?SURFACE-ACTIVE MATERIAL: Added to vinyl plastisols,

DY-201 Fluid improves the flowacteristics, de-aerates

lubricatesthe surface of the completed part.

?LUBRICANT: The fluid provides excellent lubrication fmost plastic elastomeric surfaces. Lubricity with metals depends upon thecombination involved. Care should betaken to suitable metals fpumps other itemswith moving parts.

?COSMETICS SKIN PREPARATIONS: DY-201 Fluid is an important ingredient in hcreams, skin protectants,suntan lotions, hair grooming aids because itforms a non-greasy, protective film which resists waterwaterborne irritants, yet allows the skin to breathe. Literature is available that details the use of the fluid in cosmetics.

?POLISHES CHEMICAL SPECIALITIES: DY-201 Fluid is used in most automobilefurniture polishes fits ease of application,high gloss with minimum rubbing,a durable water-repellant film. It is also usedin many other speciality formulations, including aerosol starches fabric conditioners. Additional literature is available.

?ELECTRICAL/ELECTRONIC EQUIPMENT: With excellent dielectric

properties,DY-201 Fluid can be used fboth insulating

dampingapplications.
