MIXTURE
Butanone oxime produced during curing is toxic and irritates eyes, nose and throat. Overexposure to the silane may cause coma and respiratory failure
"TLV" means the Threshold Limit Value exposure (eight-hour, time-weighted average, unless otherwise noted) established by the American Conference
of Governmental Industrial Hygienists. "STEL" indicates a short-term exposure limit. "PEL" indicates the OSHA Permissible Exposure Limit. "n/e"
indicates that no exposure limit has been established. An asterisk (*) indicates a substance whose identify is a trade secret of our supplier and unknown
to us.
3. HAZARDOUS IDENTIFICATION
Emergency Overview
Appearance, form, odor: Grey paste with mild odor
CAUTION!. Eye, skin and respiratory irritant. May be harmful if swallowed.
Potential health effects
Primary Routes of Exposure: Eye and skin contact, ingestion, inhalation
1 of 5
ITW Consumer - Devcon/Versachem
Symptoms of acute overexposure
Skin: May cause irritation and skin sensitization.
Eyes: May cause mild eye irritation
Inhalation: Causes irritation of the mouth,nose,and throat. Irritates mucous membranes. Excessive inhalation causes
headache, dizziness, nausea and incoordination.
Ingestion: May cause gastric distress (nausea, vomiting, diarrhea).
Effects of Chronic Exposure: None known.
Medical Conditions Recognized as Being Aggravated by Exposure:
Preexisting eye, skin and respiratory disorders may be aggravated by overexposure to this product.
4. FIRST AID MEASURES
Eye Contact: In case of contact, or suspected contact, immediately flush eyes with plenty of water for at least 15 minutes
and get medical attention immediately after flushing..
Skin Contact: Wipe off paste with paper towel or cloth. Wash exposed area with soap and water. Seek medical attention
if irritation persists..
Inhalation: If inhaled, remove from area to fresh air. Get medical attention if respiratory irritation develops or if breathing
becomes difficult.
Ingestion: Rinse mouth Do not induce vomiting. Slowly dilute with 1-2 glasses of water or milk and seek medical
attention. Never give anything by mouth to an unconscious person
5. FIRE FIGHTING MEASURES
Recommended Extinguishing Media: Carbon dioxide, Dry chemical, foam
Flash point: >200°F (93.3°C) Method: TCC
Lower Explosive Upper Explosive
Limit: n/d Limit: n/d
Special Fire-Fighting Procedures: Firefighters should wear self-contained breathing apparatus. Water spray may be
ineffective on flames but should be used to keep fire-exposed containers cool.
Unusual Fire/Explosion Hazards:
None.
Hazardous Products of Combustion:
Oxides of carbon, Oxides of nitrogen, Methyl ethyl ketone, possibly methyl ethyl ketoxime, Formaldehyde
6. ACCIDENTAL RELEASE MEASURES
Spill Control: Avoid personal contact. Ventilate area.
Containment: Dike, contain and absorb with clay, sand or other suitable material
Cleanup: Wipe or scrape up spill material. Clean up spill thoroughly as residue is slippery. Place in an appropriate waste
container for disposal.
Special procedures: Prevent spill from entering drainage/sewer systems, waterways and surface water.
7. HANDLING AND STORAGE
Handling precautions: Avoid contact with the skin and the eyes. Avoid breathing vapors or mists. Do not wear contact
lenses. Do not ingest.
Storage: Store away from water or moisture.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering controls:
Ventilation:
General; local exhaust ventilation as necessary to control any air contaminants to within their exposure limits (or to the
lowest feasible levels when limits have not been established) during the use of this product.
Other engineering controls: Eye wash station.
Personal protective equipment
Eye and face protection: Safety glasses with side shields
Skin protection: Rubber gloves.
Respiratory protection: With good ventilation, none required. An approved respirator (i.e.NIOSH, etc.) should be worn
when exposures are expected to exceed the applicable limits.
Comments: When heated to temperatures above 300 degrees F. in the presence of air, this product can form
formaldehyde vapors. Formaldehyde is a potential cancer hazard and a known skin and respiratory sensitizer. Safe
handling conditions may be maintained by keeping vapor concentrations below the OSHA permissible limit for
formaldehyde
9. PHYSICAL AND CHEMICAL PROPERTIES

pH (5% solution or slurry in water): n/d
10. STABILITY AND REACTIVITY
This material is chemically stable. Hazardous polymerization will not occur.
Conditions to Avoid: Exposure to moisture.
Incompatabilities: Polymerized by contact with moisture, Strong oxidizers, Acids, Iron
Hazardous Products of Combustion: Oxides of carbon, Oxides of nitrogen, Methyl ethyl ketone, possibly methyl ethyl
ketoxime, Formaldehyde

11. TOXICOLOGICAL INFORMATION
Eye Contact: No data available.
Subchronic effects: No data available.
Carcinogenicity, tertogenicity and mutagenicity: Methyl ethyl ketoxime (MEKO) is formed upon contact with water or
humid. Male rodents exposed to MEKO vapor throughout their lifetimes developed liver cancer. Until more data is
available, exposure levels should be maintained as low as possible.
Other chronic effects: Not determined.
