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 methyl ethyl ketoxime (MEKO) when exposed to water or humid air.
Provide ventilation during use to control methyl ethyl ketoxime (MEKO) within exposure guidelines or use respiratory
protection. Avoid eye contact. Avoid skin contact. Avoid breathing vapor, mist, dust, or fumes. Keep container closed.
Do not take internally.
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
22984-54-9 Methyl tri(ethylmethylketoxime) silane See ethyl methyl ketoxime comments.
Ethyl methyl ketoxime is formed upon contact with water or humid air. Provide adequate ventilation to control
exposures within the following exposure guidelines: Vendor guide TWA: 3 ppm, STEL: 10 ppm; AIHA WEEL TWA: 10
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. If skin contact occurs, change contaminated clothing as
soon as possible and thoroughly flush affected areas with cool water. Chemical protective
gloves are recommended.
Suitable Gloves: Avoid skin contact by implementing good industrial hygiene practices and procedures. Select
and use gloves and/or protective clothing to further minimize the potential for skin contact.
Consult with your glove and/or personnel protective equipment manufacturer for selection of
appropriate compatible materials.
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: 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 mealtime and end of shift. If skin contact occurs, change contaminated clothing as
soon as possible and thoroughly flush affected areas with cool water. Chemical protective
gloves are recommended.
Inhalation/Suitable Respiratory protection recommended. Follow OSHA Respirator Regulations (29 CFR
Respirator: 1910.134) and use NIOSH/MHSA 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.
Comments: Product evolves methyl ethyl ketoxime (MEKO) when exposed to water or humid air. Provide
ventilation during use to control methyl ethyl ketoxime (MEKO) within exposure guidelines or
use respiratory protection.
Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may require
added precautions.

Environmental Fate and Distribution
Air: This product is a solid consisting of a high molecular weight silicone polymer and other solid
materials. Unless milled to produce a dust or particles, it is unlikely to give rise to atmospheric
contamination.
Water: This product is a solid which is completely insoluble in water. As the specific gravity is >1, it
will sink to the bottom of the water course.
Soil: This product will enter the terrestrial environment if, as a component of municipal or industrial
solid waste the product is landfilled. It is unlikely that further significant transformation of the
product will occur.
Degradation: High molecular weight polymer which is amenable to recycling. The product is not
biodegradable. The product is removed >80% during the sewage treatment process.
Environmental Effects
Toxicity to Water This product has low water solubility and should not present a risk to aquatic organisms.
Organisms:
Toxicity to Soil Organisms: This product is a solid and does not contain significant concentrations of water soluble
constituents that may be leached from the product. It is therefore not likely to present a danger
to terrestrial organisms.
Bioaccumulation: This product is a solid which is not soluble in water and if ingested will not be absorbed.
Fate and Effects in Waste Water Treatment Plants
This product is a solid rubber type material which is unlikely to have any adverse effect on bacteria.
