CAUTION: MAY CAUSE EYE, SKIN AND RESPIRATORY TRACT IRRITATION.
Relevant routes of exposure: Skin contact, Eye contact, Inhalation
Potential Health Effects
Inhalation: Acetic acid produced during cure may irrritate eyes, nose and throat. When heated to temperatures
exceeding 300掳 F (150掳 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.
Skin contact: May cause skin irritation.
Eye contact: Vapors may irritate eyes. Contact with eyes will cause irritation.
Ingestion: Not expected to be harmful by ingestion.
Existing conditions aggravated by Eye, skin, and respiratory disorders.
exposure:
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 thoroughly with plenty of water, also under the eyelids. If eye irritation persists, consult a
specialist.
Ingestion: Do not induce vomiting. If a person feels unwell or symptoms of skin irritation appear, consult a
physician.
Notes to physician: Treat symptomatically.
5. FIRE-FIGHTING MEASURES

12. ECOLOGICAL INFORMATION
Ecological information: No specific studies have been conducted by Henkel 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.
