Dow Corning 200 FluidFeatures
• Water-clear silicone fluid available in viscosity ranging from 0.65 to 60,000 cst (mm²/s)
• Little change in physical properties over a wide temperature span - a relatively flat viscosity-temperature slope, and serviceability from -40°C up to 200°C
• Excellent water repellent
• Good dielectric properties over a wide range of temperatures and frequencies Low surface tension - readily wets clean surfaces to impart water repellent and release characteristics
• Viscosity above 10 mm²/s also exhibit heat stability, oxidation resistance, very low vapor pressures, and high flash point
• Low order of toxicity
• Essentially odorless
• Soluble in a wide range of solvents
• Non-greasy and non-rancidifying
Potydimethylsiloxane
Applications:
Release Material: Used alone or as part of a compounded formula, DOW Corning 200 Fluid provides a non-carbonizing mould release for rubber, plastics, and metal die castings. Foam Preventative: Extremely small amounts of the fluid effectively control foam in many processing operations, especially in non-aqueous systems.
Mechanical Fluid: Excellent viscosity-temperature characteristics, thermal and chemical stability, shear-breakdown resistance, compressibility, and rubber compatibility make DOW Corning 200 Fluid outstanding for mechanical/ hydraulic uses. Typical uses include hydrolic stabilisers, damping media.
Surface-Active Material: Added to vinyl plastisols, DOW Corning 200 Fluid improves the flow characteristics, de-aerates and lubricates me 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. | |

Dow Corning 203 FluidRelease agent for molding, extruding and fabricating rubber and plastic parts, and in die casting metals
Features
Compatible with most organic coatings and adhesive systems
Provides a heat-stable film
Does not require unusual or extraordinary cleaning operations prior to painting, plating or bonding
Composition
Alkylaryl polysiloxane fluid
Uses
Dow Corning® 203 Fluid can be used for a wide variety of applications. It can be used for the production of floor mats and tiles, seals, grommets, gaskets, toys, paneling, decorative trim, household appliance assemblies, and similar plastic or rubber products that are coaled, painted, plated or bonded.
It is also highly effective as a parting agent in die casting aluminum, zinc, magnesium and other metals. In addition, Dow Corning 203 Fluid can be used as an additive in rubber and plastic formulations. When added as a built-in lubricant, the fluid facilitates the assembly of mechanical components and acts as a lubricant in service.

Typical Properties:
Specification Writers: These values are not intended for use in preparing specifications. Please contact your local Dow Corning sales office or your Global Dow Corning Connection before writing specifications on this product
| Test | Unit | Result | | Appearance | | clear, amber liquid | | Sulfur content | % | 22.7 | | Average Sulfur Chain Length | | 3.75 |
Description
Dow Corning® Z-6940 Silane is a mixture of polysulfidosilane species with an average sulfur chain length of 3.75. It is a 100% actives product in a liquid form.
How to Use
As with any organofunctional alkoxysilane coupling agent, Dow Canting Z-6940 Silane can be applied as a primer or incorporated in-situ in a compound formulation.
As a primer of a surface, the silane can be dispersed in ethanol at about 1% and wiped onto a substrate.
As an in-situ treatment, the silane is typically added with the organic matrix and inorganic filler/reinforcement. In the case of black rubber, oil silane is added with the rubber, oil and silica in the first mix. The ethoxysilyl groups then react to the surface of the inorganic material during this mix. It is typical to drive the temperature of the mixture to over 150°C to get adequate reaction of the silane to the
filler. | |
