Immediately flush with water for 15 minutes. Seek medical attention.
Skin Contact
Remove from skin and wash throughly with soap and water or waterless cleanser. Get
medical attention if irritation or other ill effects develop or persist.
Inhalation
Material is not likely to present an inhalation hazard at ambient conditions. If material is
heated or vapor/mist/dust/fumes are generated, care should be taken to prevent inhalation.
In case of exposure to vapor/mist/dust/fumes, move to fresh air.

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 or Explosion Hazards
None known
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
Formaldehyde
Silicon dioxide
Depending on color, hazardous decomposition products may also include:
Hydrogen
Nitrogen oxides
Metal oxides
Sulfur oxides
6. Accidental Release Measures
Steps to be taken in case of spill or release
Observe all personal protection equipment recommendations in Sections 5 and 8. Wipe 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 information about personal protective equipment for spills. Contact
Accumetric, LLC if additional information is required.
7. Handling and Storage
Handling
Use adequate ventilation. Product evolves acetic acid when exposed to water or humid air.
Provide ventilation during use to control acetic acid within exposure guidelines or use
respiratory protection. Avoid eye contact. Avoid skin contact. Keep container closed. Do
not take internally. Avoid breathing vapor.
Storage
Use reasonable care and store away from oxidizing materials. Keep container closed and
store away from water or moisture.

8. Exposure Controls and Personal Protection
Component Exposure Limits
Component Name: Ethyltriacetoxysilane
CAS Number: 17689-77-9
Exposure Limits: See acetic acid comments
Component Name: Methyltriacetoxysilane
CAS Number: 4253-34-3
Exposure Limits: 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.
Component Exposure Limits - Almond only
Component Name: Dimethylsiloxane, trimethoxysilyl-terminated
CAS Number: PMN871176
Exposure Limits: See methyl alcohol comments.
Component Name: Aluminum
CAS Number: 7429-90-5
Exposure Limits: OSHA PEL (final rule): TWA 15mg/m3 total dust, 5 mg/m3 respirable dust.
ACGIH TLV: TWA 10mg/m3
Methyl alcohol forms on contact with water or humid air. Provide adequate ventilation to
control exposures within guidelines of OSHA PEL: TWA 200 ppm and ACGIH TLV-skin: TWA
200 ppm, STEL 250 ppm.
Component Exposure Limits - Aluminum only
Component Name: Aluminum
CAS Number: 7429-90-5
Exposure Limits: OSHA PEL (final rule): TWA 15mg/m3 total dust, 5 mg/m3 respirable dust.
ACGIH TLV: TWA 10mg/m3
Engineering Controls
Local Ventilation: Recommended
General Ventilation: Recommended
Eye Protection
Use proper protection - safety glasses as a minimum.
Skin Protection
Wash at mealtimes and end of shift. Contaminated clothing and shoes should be removed
as soon as practical and throughly cleaned before reuse. Chemical protective gloves are
recommended.
Suitable Gloves:
Nitrile Rubber. Butyl Rubber.
Inhalation
Use respiratory protection unless adequate local exhaust ventilation is provided or exposure

assessment demonstrates that exposures are within recommended exposure guidelines. IH
personnel can assist in judging the adequacy of existing engineering controls.
Suitable Respirator
Respiratory protection is not needed under ambient conditions. If vapor/mist/dust/fumes are
generated when material is heated or handled, the following is advised. General and local
exhaust ventilation is recommended to maintain vapor exposures below recommended
limits. Where concentrations are above recommended limits or are unknown, appropriate
respiratory protection should be worn. Follow OSHA respirator regulations (29 CFR
1910.134) and use NIOSH/MSHA approved respirators.
Personal Protective Equipment for Spills
Eyes: Use full face respirator.
Skin: Wash at mealtimes and end of shift. Contaminated clothing and shoes should be
removed as soon as practical and throughly cleaned before reuse. Chemical protective
gloves are recommended.
Inhalation/Suitable Respirator: Respiratory protection recommended. Follow OSHA
Respirator Regulations (29 CFR 1910.134) and use NIOSH/MSHA approved respirators.
Protection provided by air purifying respirators against exposure to any hazardous chemical
is limited. Use a positive pressure air supplied respirator if there is any potential for
uncontrolled release, exposure levels are unknown, or any other circumstance where air
purifying respirators may not provide adequate protection.
Precautionary Measures
Avoid eye contact. Avoid skin contact. Avoid breathing vapor, mist, dust or fumes. Keep
container closed. Do not take internally. Use reasonable care.
Comment
Product evolves acetic acid when exposed to water or humid air. Provide ventilation during
use to control acetic acid within exposure guidelines or use respiratory protection. When
heated to temperatures above 150C 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 temperatures or
aerosol/spray applications may require added precautions.
