No known applicable information.
Medical Conditions Aggravated by Exposure
No known applicable information.
The above listed potential effects of overexposure are based on actual data, results of studies performed upon similar compositions,
component data and/or expert review of the product. Please refer to Section 11 for the detailed toxicology information.
4. FIRST AID MEASURES
Eye: Immediately flush with water for 15 minutes. Get medical attention.
Skin: Remove from skin and wash thoroughly with soap and water or waterless cleanser. Get
medical attention if irritation or other ill effects develop or persist.
Inhalation: No first aid should be needed.
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 Temperature: Not determined.
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. Use water spray to keep fire exposed containers cool. Determine
the need to evacuate or isolate the area according to your local emergency plan.
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: Silicon dioxide. Carbon oxides and traces of incompletely burned carbon compounds.
Formaldehyde.

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
spilled 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 (989) 496-5900, if additional information is
required.
7. HANDLING AND STORAGE
Use with adequate ventilation. Product evolves acetic acid (HOAc) when exposed to water or humid air. Provide
ventilation during use to control HOAc within exposure guidelines or use respiratory protection. Avoid eye contact. Avoid
skin contact.
Keep container closed and store away from water or moisture.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Component Exposure Limits
CAS Number Component Name Exposure Limits
4253-34-3 Methyltriacetoxysilane See acetic acid comments.
17689-77-9 Ethyltriacetoxysilane 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.
