SECTION 3 ?HAZARDS IDENTIFICATION
MAIN SYMPTOMS:
EYE: Direct contact irritates moderately with redness and swelling.
SKIN: A single short exposure (less than 24 hours) may irritate. Repeated prolonged contact (24 to 48 hours) may irritate
moderately. MDI may cause irritation to the skin or mucous membranes. Ethyl benzene may be absorbed through
the skin.
INHALATION: Vapor overexposure, and/or inhalation may severely irritate eyes, nose, throat, upper respiratory tract, and lungs.
Vapor overexposure may cause drowsiness. Inhalation of high concentrations of xylene, or ethyl benzene may
cause respiratory irritation or difficulties and central nervous system effects characterized by headache, nausea,
dizziness, and/or drowsiness. MDI vapors or mist can cause irritation of upper respiratory tract: signs/symptoms
can include soreness of the nose and throat, coughing, and sneezing. Persons previously sensitized to
isocyanates may experience an allergic respiratory reaction: signs/symptoms can include difficulty breathing,
wheezing, tightness of chest, and respiratory failure.
ORAL: Swallowing may cause digestive discomfort and gastrointestinal irritation. Ingestion of xylene may cause central
nervous system effects. Aspiration of xylene or ethyl benzene into lungs may cause chemical pneumonitis.
NFPA HAZARD CODES: Health: 2 Flammability: 2 Reactivity: 0
SECTION 4 ?FIRST-AID PROCEDURES
INHALATION: Remove to fresh air. If ill effects persist get medical attention.
SKIN CONTACT: Remove from skin and wash thoroughly with soap and water or waterless cleanser.
Get medical attention if irritation or other ill effects develop or persist.

INTERNATIONAL:
Canada
This product has been classified according to the hazard criteria of the CPR and the MSDS contains all the information required by the
CPR.
Canadian DSL
All ingredients in this product are currently listed on the Canadian Domestic Substances List (DSL) except the non-hazardous
polyurethane prepolymer and dimorpholine ethane, which are both on the NDSL. (Based upon the concentration of the prepolymer in the
formulation, it would require over 128,000 10.1 fl.oz. cartridges of Low VOC 25 to reach the 10,000 kg yearly limit for an NDSL polymer
approved under Schedule VI before reporting is required. This is equal to approximately 49 200-Gal batches of Low VOC 25. There is
also a cumulative limit of 50,000 kg that can take many years to reach, assuming no one year exceeds the 10,000 kg limit. The
dimorpholine ethane is in such small quantities that it would require millions of cartridges to reach the yearly limit.) The substances that
are on the DSL would not be considered new for the purposes of the Canadian Environmental Protection Act (CEPA).
Note:
The recipient of this product should be aware of the possible existence of additional local regulations, which may be applicable to this
product.
SECTION 16 ?OTHER INFORMATION
These data are offered in good faith as typical values and not as a product specification. No warranty, either expressed or implied, is hereby
made. The recommended industrial hygiene and safe handling procedures are believed to be generally applicable. However, each user
