Part Nos. 49390, 49391, 49392
Autoignition Point (Solids) : Not Available
Special Firefighting Procedures and Unusual Fire and
Explosion Hazards : Use self-contained breathing apparatus, pro-
tective clothing, foams with water.
Extinguishing Media : Water Spray, foam, dry chemical, carbon di-
oxide.
SECTION V ?HEALTH HAZARD DATA
THE INFORMATION SHOWN BELOW REFERS GENERALLY TO A COMPONENT
OF THE PRODUCT BUT AS REQUIRED BY OSHA 1910.1200 THE HAZARDS OF
ANY INGREDIENT MUST BE EXTENDED TO THE PRODUCT AS A WHOLE
UNLESS TESTING OF THE PRODUCT HAS BEEN PERFORMED. THE U.S.
AMERICAN NATIONAL STANDARD (ANSI) Z129.1-1982 WAS USED AS A GUIDE
WHEN THIS MSDS WAS WRITTEN.
Ingestion : No hazard known at this time.
Absorption : No hazard known at this time.
Inhalation : Hazardous if inhaled.
IMPORTANT NOTE:
IN ANIMAL TESTING ON ALBINO RATS, MDI AEROSOL PARTICLES SMALL
ENOUGH TO BE INHALED ARE RATED HIGHLY TOXIC ACCORDING TO OSHA
CRITERIA. HOWEVER, THE POLYURETHANE DIVISION OF THE SOCIETY OF
THE PLASTICS INDUSTRY, INC. HAS PETITIONED DOT TO DECLASSIFY MDI
WHICH HAS BEEN RATED A DOT POISON. IN THEIR PETITION SPI STATES:
"...EVEN IN A LABORATORY SETTING, IT IS VERY DIFFICULT TO CREATE A
RESPIRABLE AEROSOL ATMOSPHERE OF MDI CAPABLE OF CAUSING
BIOLOGICAL HARM BECAUSE OF MDI'S VERY LOW VAPOR PRESSURE AND
HIGH VISCOSITY WHEN IN LIQUID FORM."
LABORATORY TESTING HAS BEEN THAT SIMULATED THE USE OF OUR
SEALANTS AND ADHESIVE PRODUCTS. WHEN THE TRADITIONAL METHODS
OF APPLICATION, CAULKING TUBES, TROWEL, SPATULA, ETC. ARE USED,
THE OPPORTUNITY FOR AESOSOL FORMATION IS ESSENTIALLY
NONEXISTANT. IN TESTS ON OUR SEALANT PRODUCTS, THE ACGIH TLV OF 5
PARTS PER BILLION FOR MDI WAS NOT EXCEEDED EVEN IN THE AIR
IMMEDIATELY ADJACENT TO MULTIPLE EXTRUDED BEADS OF SEALANT.
WHERE LARGE AREAS OF SEALANT OR ADHESIVE TYPE PRODUCTS ARE
APPLIED, DYNATEX DOES RECOMMEND THAT ADEQUATE VENTILATION BE
USED TO BE SURE THAT THE ACGIH TLV OF NEITHER THE MDI NOR ANY
OTHER HAZARDOUS CONSTITUENT IS EXCEEDED IN THE WORK AREA.
Contact : Ingredient causes eye and/or skin irritation.
Corrosion : No hazard known at this time.
: Combustible liquid, flash point >1000F

FIRST AID:
Inhalation : If inhaled, remove to fresh air. If not breath-
ing, give artificial respiration, preferably mouth
to mouth. If breathing is difficult, give oxygen.
Call a physician.
Contact : In case of contact, immediately flush eyes
with plenty of water for at least 15 minutes. Call
a physician.
IN CASE OF FIRE, USE EXTINGUISHING AGENTS RECOMMENDED.
Symptoms of Overexposure : Irritation, sore throat, breathlessness, chest
pain, coughing, sensitizer, nausea.
Medical Conditions Aggravated by Exposure : Bronchial hyperactivity, asthma.
Entry Route : Contact, inhalation.
Chronic Effects : Long term overexposure to the hazardous ma-
terials in this product has been associated with
asthma, lung impairment, possible respiratory
sensitizaiton.
Target Organs : Eyes, respiratory system, lung.
NONE OF THE INGREDIENTS IN THE PRODUCT EXCEEDING A CONCENTRA-
TION LIMIT OF 0.1% ARE ON THE IARC, NTP OR OSHA LISTS OF CARCINO-
GENIC HAZARDS.
SECTION VI ?REACTIVITY DATA
Stability : Stable
Materials to Avoid : Alkalis, acids, alcohols, detergents, water.
Hazardous Decomposition Products : Unknown due to the complex nature of this
material. Fumes from complete or incomplete
combustion of this material may include carbon
dioxide, carbon monoxide, water vapor, oxides
of nitrogen or a wide variety of innocuous or
toxic fumes. Aldehydes, hydrogen chloride,
traces of hydrogen cyanide may also be pro-
duced.
Hazardous Polymerization : Can occur with moisture and other isocyanate
reactants.
SECTION VII ?SPILL OR LEAK PROCEDURES
Steps to be Taken When Material is Spilled or
Released : Sweep up material using sweeping compound
and package the solid products in steel drums
which are in good condition. Thoroughly clean
area where spill occurred.

Waste Disposal Method : Dispose of in accordance with Federal, State
and Local rules. Be aware that state and local
requirements may differ widely depending on
location and may in many cases be different
from federal rules. This product, if unaltered or
mixed with any other materials, contains the
following contaminants listed in 40CFR Part
261.24, toxicity characteristic that exceed maxi-
mum allowable concentrations and therefore is a
hazardous waste with the EPA D___ number(s)
shown below.
D043 Vinyl Chloride 1ppm
IF THE PRODUCT HAS BEENALTERED, PARTICULARLY TO THE POINT WHERE
FILTERABLE SOLIDS ARE PRESENT AT OVER A 0.5% LEVEL, CLASSIFICATION
IS A COMPLEX ISSUE AND DEPENDS ON THE LEVEL OF CONTAMINANTS IN
THE LIQUID PORTION COMBINED WITH AN EXTRACT OF THE SOLID
PORTION. YOUR HAZARDOUS WASTE REMOVAL CONTRACTOR WILL BE
ABLE TO ASSIST YOU IN THIS CASE. IT IS ALSO A D001 CHARACTERISTIC
IGNITABLE WASTE.
SECTION VIII ?SPECIAL PROTECTION INFORMATION
Ventilation : Local Exhaust is preferred to keep vapors/
particulates below the TLV value. Mechanical
areawide ventilation is acceptable.
Protective Gloves : Neoprene rubber, nitrile, impervious plastic.
Eye Protection : Safety glasses are recommended.
Other Protection : Safety shower and eye bath.
SECTION IX ?SPECIAL PRECAUTIONS
: Store in a cool location (600F ?800F) away
Precautions for Handling and Storing
from sunlight and any source of heat, sparks or
flame. Keep container tightly closed when not
being used.
Other Precautions : Use with adequate ventilation, avoid pro-
longed or repeated breathing of vapors. Avoid
skin contact. Use in area free from flame and
sparks.
