Dimethyl Silicone Fluid (AS-201)

AS-201 Dimethyl Silicone Fluid
50-1, 000, 000 cSt
Description:
AS-201# Dimethyl Silicone Fluid is a kind of colorless, clear, transparent and odorless liquid, is a high viscosity Polydimethyl-siloxane polymer. Depending on using applicants, it has various viscosities from low to high, covering from 50cSt to 1, 000, 000cSt.
Applications:
For industrial applications:
Silicone fluids meet a wide variety of applications in many industries. They are good coatings additive, plastics additive, damping fluid, plastics lubricant, electrical insulating fluid, mechanical fluid, de-foaming, mold release and surface active agent for machinery, electrical appliances, and textile...It is also used as active ingredient in a variety of automotive, furniture, metal, leather and specialty polishes, etc
For personal care applications:
They are ideal conditioning agent/additive for hair care products, shampoo, rinse-off conditioners, bath shower gel and other personal care and cosmetic products. It provides easy combing and detangling for wet and dry hair, lubricious, smooth feel as well as softness and gloss to the hair.
Composition
Linear polydimethylsiloxane polymers typically have the following typical chemical composition: (CH3)3SiO[SiO(CH3)2]nSi(CH3)3

How to Use:
1. The products list here is for industrial use; It is neither tested nor represented as suitable for medical, pharmaceutical uses or food use.
2. Silicone fluid usually contains 100 to 200ppm dissolved water. Control humidity carefully, especially when using the fluid as electrical insulation oil.
3. For personal care applications as a conditioning additive, Silicone Fluid should be pre-emulsified to the desired particle size, incorporated into a shampoo base and post-stabilized. Alternatively, it can be directly emulsified into a hair care formulation. The high-molecularweight dimethicone provides easy combing and detangling for wet or dry hair, and adds softness, smoothness and gloss.
4. Used as a defoamer for oil-based foaming fluids, it provides effective foam control at extremely small addition levels.

Storage, Transportation and Safety
1. Keep these products in tightly sealed containers and store in a dark, cool location. Don't let silicone fluid contact the strong acid, alkali, lead, tin, selenium, tellurium and other substances. The shelf life is 1 year.
2. Transportation as no-toxic and non-dangerous product.
3. Avoid contact with skin and mucosa. If it contacts the skin, wipe off with a washcloth and rinse thoroughly with soap and running water.
4. If silicone fluid enters the eye, wash it away immediately with large volumes of water for at least 15 minutes and ask for medical attention if necessary.
5. Use extensive ventilating when handling.
