DOW CORNING 200(R) FLUID, 10 CST.

Containment/Clean up: Determine whether to evacuate or isolate the area according to your local emergency

plan. Observe all personal protection equipment recommendations described in
Sections 5 and 8. For large spills, provide diking or other appropriate containment to
keep material from spreading. If diked material can be pumped, store recovered
material in appropriate container. Clean up remaining materials from spill with suitable
absorbant. Clean area as appropriate since some silicone materials, even in small
quantities, may present a slip hazard. Final cleaning may require use of steam,
solvents or detergents. Dispose of saturated absorbant or cleaning materials
appropriately, since spontaneous heating may occur. Local, state and federal laws and
regulations may apply to releases and disposal of this material, as well as those
materials and items employed in the cleanup of releases. You will need to determine
which federal, state and local laws and regulations are applicable. Sections 13 and 15
of this MSDS provide information regarding certain federal and state requirements.

Note: See section 8 for Personal Protective Equipment for Spills. Call Dow Corning Corporation, [phone],
if additional information is required.

12. ECOLOGICAL INFORMATION

Page: 5 of 8

Environmental Fate and Distribution

Air: This product is a high molecular weight liquid polymer which has a very low vapour

pressure (<1 mm Hg). As a result it is unlikely to become an atmospheric contaminant
unless generated as an aerosol.

Water: This product has a very low water solubility (< 100 ppb). As it has a specific gravity of

< 1, if discharged to water, it will initially form a surface film. As the product is non
volatile and has a high binding affinity for particulate matter, it will adsorb to
particulates and sediment out.

Soil: If discharged to surface water, this product will bind to sediment. If discharged in

effluent to a waste water treatment plant, the product is removed from the aqueous
phase by binding to sewage sludge. If the sewage sludge is subsequently spread on
soil, the silicone product is expected to degrade.

Degradation: This product, polydimethylsiloxane, degrades in soil abiotically to form smaller

molecules. These in turn are either biodegraded in soil or volatilized into the air where
they are broken down in the presence of sunlight. Under appropriate conditions, the
ultimate degradation products are inorganic silica, carbon dioxide and water vapour.
Due to the very low water solubility of this product, standard OECD protocols for ready
and inherent biodegradability are not suitable for measuring the biodegradability of this
product. The product is removed >80% during the sewage treatment process.

Environmental Effect s

Toxicity to Water
Organisms:

Based on analogy to similar materials this product is expected to exhibit low toxicity to
aquatic organisms.

DOW CORNING CORPORATION

Material Safety Data Sheet

Page: 6 of 8

DOW CORNING 200(R) FLUID, 10 CST.

Toxicity to Soil Organisms: Experiments show that when sewage sludge containing polydimethylsiloxane is added

to soil, it has no effect on soil micro-organisms, earthworms or subsequent crops
grown in the soil.

Bioaccumulation: This product is a liquid and is a high molecular weight polymer. Due to its physical size

it is unable to pass through, or be absorbed by biological membranes. This has been
confirmed by testing or analogy with similar products.

Fate and Effects in Waste Water Treatment Plants

This product or similar products has been shown to be non-toxic to sewage sludge bacteria.
