SECTION 2 - HAZARDOUS INGREDIENTS

Principal Hazardous Components(s) (Chemical & Common Name(s))



This mixture has not been evaluated as a whole. All ingredients are bound in a polymer matrix and potential for hazardous

exposure as shipped is minimal. However, some fumes may be released upon heating or vulcanization and the end-user

(fabricator) must take the necessary precautions (mechanical ventilation, respirator program, etc.) to protect his employees

from exposure. (See Section 7 - Special Precautions).



The following ingredients are considered hazardous per OSHA 1910.1200. MSDS for each is attached.
