3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
HMIS:
Physical state: Paste HEALTH: 1
Color: Black FLAMMABILITY: 1
Odor: Mild PHYSICAL HAZARD: 0
Personal Protection: See Section 8
CAUTION: CAUSES EYE, SKIN AND RESPIRATORY TRACT IRRITATION
Relevant routes of exposure: Skin, inhalation, eyes, Ingestion
Potential Health Effects
Item number: 30509 Product name: Loctite(R) Instant Gasket
1 of 5
Inhalation: Vapors and mist irritate the respiratory tract and nasal passages. When heated to temeraptures
exceeding 300?F (150?C) in the presence of air, silicones may form formaldehyde vapors.
Formaldehyde is a potential cancer hazard and a known skin and respiratory sensitizer. Vapors irritate
the eyes, nose and throat. Safe handling conditions may be maintained by keeping formaldehyde
vapor concentrations below the OSHA permissible limt. The silane is a skin and eye irritant and may
cause skin burns. Overexposure may cause coma and respiratory failure. The low concentration
makes such overexposure unlikely and minimizes its affect on health and safety.
Skin contact: May cause skin irritation with discomfort or rash.
Eye contact: Vapors may irritate eyes. Contact with eyes will cause irritation.
Ingestion: Moderately toxic by ingestion. Not expected under normal conditions of use.
Existing conditions aggravated by exposure: Skin disorders.
See Section 11 for additional toxicological information.
4. FIRST AID MEASURES
Inhalation: Remove to fresh air. If discomfort persists seek medical attention.
Skin contact: Wipe off paste with paper towel or cloth. Wash with soap and water.
Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical
attention.
Ingestion: Do not induce vomiting. Keep individual calm. Obtain medical attention.

6. ACCIDENTAL RELEASE MEASURES
Environmental precautions: Do not flush into surface water or sanitary sewer system.
Clean-up methods: Scrape up as much material as possible. Maintain good ventilation for large spills. Place scrap
material in a well ventilated area and allow to cure to rubber.

Incompatible products: Never allow product to get in contact with water during storage.
For information on product shelf life contact Henkel Loctite Customer Service at (800) 243-4874.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering controls: Use local exhaust ventilation to maintain airborne concentrations below established exposure limits.
Respiratory protection: Use a NIOSH approved air-purifying respirator if the potential to exceed established exposure limits
exists.

12. ECOLOGICAL INFORMATION
Ecological information: No specific studies have been conducted by Loctite on the ecotoxicity or environmental fate of this
material; however, commonly available data on the material indicate that uncontrolled releases to soil,
groundwater, or surface waters could entail acute and/or chronic ecological effects, depending on the
quantity and concentration of such releases. Releases of volatile components to the atmosphere are
not believed to entail significant ecological consequences provided such releases are within the
exposure levels set forth in this document. Accordingly, all appropriate measures should be taken to
avoid uncontrolled releases to the environment, and any spills or other uncontrolled releases which
may occur should be contained and cleaned up immediately in accordance with Section 6.
13. DISPOSAL CONSIDERATIONS
Information provided is for unused product only.
Recommended method of disposal: Cured rubber can be incinerated or landfilled following EPA and local regulations.
