This information must be included in all MSDS's that are copied and distributed for this material. WARNING: This
product contains a chemical known to the state of California to cause cancer, birth defects, or other reproductive harm.
Special Note for urethane hardener formulas: The HDI monomer (CAS 822-06-0) is present as a byproduct at a low level in
the basic formula. When properly admixed (with the base component) for spray application the average level of the
monomer component falls below normal reportable limits. However; upon aging it may rise to a reportable level (admixed).
Always follow the protection guidelines presented in this document.
WARNING: This product contains flammable solvent(s).

See California warnings in Section II.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE
OVER EXPOSURE TO SECTION II COMPONENTS CAN AGGRAVATE PRE-EXISTING DISORDERS OF KIDNEYS, LIVER AND RESPIRATORY SYSTEM.
EMERGENCY AND FIRST AID PROCEDURES
EYES: FLUSH GENTLY WITH WATER FOR 15 MINUTES, IF ANY IRRITATION PERSISTS, SEEK MEDICAL ATTENTION.
SKIN: WASH AFFECTED AREA WITH SOAP AND WATER, IF ANY IRRITATION DEVELOPS AND PERSISTS, SEEK MEDICAL ATTENTION.
INHALATION: REMOVE TO FRESH AIR, IF DIZZINESS OR NAUSEA PERSISTS, SEEK MEDICAL ATENTION.
=========== SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE ============
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
SOAK UP WITH INERT ABSORBENT. DO NOT ALLOW MATERIAL TO ENTER DRAINS, SEWER SYSTEM. VENTILATE AREA.
WASTE DISPOSAL METHOD
HAZARDOUS WASTE REGULATIONS ARE NOT CONSISTENT THROUGHOUT THE COUNTRY (SOME WASTES ARE NOT HAZARDOUS WASTE UNDER FEDERAL
RULES, BUT THE SAME WASTE MAY BE DEFINED AS HAZARDOUS WASTE UNDER STATE RULES).
ANY SPILLS SHOULD BE SOAKED UP WITH INERT ABSORBANT AND COLLECTED IN CONTAINERS. PAINT BOOTH FILTERS MAY BE CONSIDERED
HAZARDOUS.
CONTACT YOUR LOCAL HAZARDOUS WASTE AGENCY (WITH INFORMATION FROM THIS MSDS) FOR PROPER DISPOSAL INSTRUCTIONS.

PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING
USE ONLY WITH VENTILATION THAT KEEPS SECTION II COMPONENTS BELOW PERMISSABLE EXPOSURE LIMITS. KEEP CONTAINERS UPRIGHT
AND SEALED. AVOID STORAGE ABOVE 120 Deg.F. KEEP FROM FREEZING.
OTHER PRECAUTIONS
AVOID SKIN AND EYE CONTACT. DO NOT BREATHE VAPORS. DO NOT TAKE INTERNALLY. USE ONLY WITH ADEQUATE VENTILATION. DUST
FROM SANDING THE DRIED MATERIAL SHOULD BE TREATED AS NUISANCE DUST - THE USE OF A PARTICULATE DUST MASK IS RECOMMENDED.
ALL PERSONS WHO USE THIS MATERIAL SHOULD READ AND UNDERSTAND ALL MANUFACTURERS' INSTRUCTIONS AND PRECAUTIONS PRIOR TO
USE. THIS MATERIAL IS INTENDED FOR USE IN AN INDUSTRIAL ENVIRONMENT BY TRAINED PERSONNEL ONLY.
===================== SECTION VIII - CONTROL MEASURES ======================
RESPIRATORY PROTECTION
Respirator Guidelines for spray application of two component acrylic urethane finishes:
Good industrial hygiene practice dictates that when isocyanate containing coatings are spray applied, some form of
respiratory protection should be worn. During the spray application of coatings containing this product, the use of a
supplied-air (either positive pressure or continuous flow type) respirator is mandatory when one or more of the
following conditions exists:
?The airborne isocyanate concentrations are not known; or
?The airborne isocyanate monomer concentrations exceed 0.05 ppm averaged over eight (8) hours (10 times the 8 hour TWA
exposure limit); or
?The airborne polyisocyanate (polymeric, oligomeric) concentrations exceed 5 mg/m3 averaged over 8 hours or 10 mg/m3
averaged over 15 minutes (10 times the 8 hour TWA or the 15 minute STEL exposure limits); or
?Operations are performed in a confined space (see OSHA Confined Space Standard, 29 CFR 1910.146).
A properly fitted air-purifying (combination organic vapor and particulate) respirator, proven by test to be effective
in isocyanate-containing spray paint environments, and used in accordance with all recommendations made by the
manufacturer, can be used when all of the following conditions are met:
?The airborne isocyanate monomer concentrations are known to be below 0.05 ppm averaged over eight (8) hours (10 times
the 8 hour TWA exposure limit); and
?The airborne polyisocyanate (polymeric, oligomeric) concentrations are known to be below 5 mg/m3 averaged over 8 hours
or 10 mg/m3 averaged over 15 minutes (10 times the 8 hour TWA or the 15 minute STEL exposure limits); and
?A NIOSH-certified (National Institute of Occupational Safety and Health) End of Service Life Indicator or a change
schedule based upon objective information or data is used to ensure that cartridges are replaced before the end of their
service life. In addition, prefilters should be changed whenever breathing resistance increases due to particulate
buildup
VENTILATION
SUFFICIENT TO KEEP SECTION II COMPONENTS BELOW THEIR EXPOSURE LIMITS
PROTECTIVE GLOVES
IMPERVIOUS GLOVES ARE RECOMMENDED (CONSULT INDUSTRIAL HYGIENIST).
EYE PROTECTION
SAFETY GLASSES WITH SIDE SHIELDS ARE RECOMMENDED TO PREVENT CONTACT, WEAR IMPERVIOUS CLOTHING AND BOOTS.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT
EYE WASH STATION. TO PREVENT REPEATED OR PROLONGED CONTACT, WEAR IMPERVIOUS CLOTHING AND BOOTS.
WORK/HYGIENIC PRACTICES
WASH HANDS BEFORE EATING.
