Oral: No first aid should be needed.

Comments: Treat according to person's condition and specifics of exposure.

5. FIRE FIGHTING MEASURES

Flash Point: Not applicable.

Autoignition Not determined.
Temperature:

Flammability Limits in Air: Not determined.

Extinguishing Media: On large fires use dry chemical, foam or water spray. On small fires use carbon dioxide
(CO2), dry chemical or water spray. Water can be used to cool fire exposed containers.

Fire Fighting Measures: Self-contained breathing apparatus and protective clothing should be worn in fighting
large fires involving chemicals. Determine the need to evacuate or isolate the area
according to your local emergency plan. Use water spray to keep fire exposed
containers cool.

Unusual Fire Hazards: None.

Hazardous Decomposition Products

Thermal breakdown of this product during fire or very high heat conditions may evolve the following hazardous
decomposition products: Carbon oxides and traces of incompletely burned carbon compounds. Silicon dioxide.

Containment/Clean up: Observe all personal protection equipment recommendations described in Sections 5
and 8. Wipe up or scrape up and contain for salvage or disposal. 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, (989) 496-5900,
if additional information is required.
7. HANDLING AND STORAGE

Use with adequate ventilation. Avoid eye contact. Avoid skin contact.

Use reasonable care and store away from oxidizing materials. Keep container closed and store away from water
or moisture.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Component Exposure Limits

CAS Number Component Name Exposure Limits

17689-77-9 Ethyltriacetoxysilane See acetic acid comments.

4253-34-3 Methyltriacetoxysilane See acetic acid comments.

Acetic acid is formed upon contact with water or humid air. Provide adequate ventilation to control exposures
within guidelines of OSHA PEL: TWA 10 ppm and ACGIH TLV: TWA 10 ppm, STEL 15 ppm.

Engineering Controls

Local Ventilation: Recommended.
General Ventilation: Recommended.

Personal Protective Equipment for Routine Handling

Eyes: Use proper protection - safety glasses as a minimum.

Skin: Wash at mealtime and end of shift. Contaminated clothing and shoes should be
removed as soon as practical and thoroughly cleaned before reuse. Chemical
protective gloves are recommended.

Suitable Gloves: Silver Shield(R). 4H(R).

Inhalation: No respiratory protection should be needed.

Suitable Respirator: None should be needed.

Personal Protective Equipment for Spills

Eyes: Use proper protection - safety glasses as a minimum.

Skin: Wash at mealtime and end of shift. Contaminated clothing and shoes should be
removed as soon as practical and thoroughly cleaned before reuse. Chemical
protective gloves are recommended.

Inhalation/Suitable No respiratory protection should be needed.
Respirator:

Precautionary Measures: Avoid eye contact. Avoid skin contact. Use reasonable care.

Comments: When heated to temperatures above 150 degrees C in the presence of air, product can
form formaldehyde vapors. Formaldehyde is a potential cancer hazard, a known skin
and respiratory sensitizer, and an irritant to the eyes, nose, throat, skin, and digestive
system. Safe handling conditions may be maintained by keeping vapor concentrations
within the OSHA Permissible Exposure Limit for formaldehyde.


Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may
require added precautions.
