SECTION 3 鈥? HAZARDS IDENTIFICATION

Please note that as a service to our customers, hazard warnings and information have been included for ALL chemicals listed in
this MSDS. However, not all of these chemicals are defined as 鈥渉azardous鈥? by ISO or OSHA standards. Only those chemicals
listed in Section 2 of this MSDS are defined by ISO and/or OSHA as 鈥渉azardous鈥? based upon the properties and concentrations of
each chemical.

MOST IMPORTANT HAZARDS
MAIN SYMPTOMS:
EYE: Direct contact irritates moderately with redness and swelling. Calcium carbonate, xylene, calcium oxide, and
MDI may cause severe eye irritation, especially in dust form. Butyl benzyl phthalate (BBP) may cause irritation
with symptoms of redness and itching.
SKIN: A single short exposure (less than 24 hours) may irritate. Repeated prolonged contact (24 to 48 hours) may
irritate moderately. Product contains calcium carbonate, xylene, and calcium oxide, which are possible skin
sensitizers. Contact with BBP may cause irritation with symptoms of redness and itching. MDI may cause
irritation to the skin or mucous membranes. Ethyl benzene may be absorbed through the skin.

MATERIAL SAFETY DATA
SHEET

PARATHANE 35SL POLYURETHANE SEALANT

INHALATION: Vapor overexposure may severely irritate eyes, nose, throat, upper respiratory tract, and lungs. Vapor
overexposure may cause drowsiness. Excessive inhalation of calcium carbonate (dust form) may result in
shortness of breath or reduced pulmonary function. Inhalation of high concentrations of BBP, 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.
Overexposure to titanium dioxide (dust form) may cause pulmonary fibrosis (scarring of the lungs).
ORAL: Small amounts transferred to the mouth by fingers during use, etc. should not injure. Swallowing large
amounts may cause digestive discomfort and gastrointestinal irritation. Ingestion of BBP may cause central
nervous system depression with symptoms seen in acute inhalation. 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 鈥? 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.
EYE CONTACT: Immediately flush with water for 15 minutes. Get medical attention.
INGESTION: Get medical attention.
COMMENTS: Treat according to person鈥檚 condition and specifics of exposure.


SECTION 5 鈥? FIRE-FIGHTING MEASURES

SUITABLE EXTINGUISHING MEDIA: Carbon Dioxide (CO2), water fog (or spray), dry chemical, foam.
UNSUITABLE EXTINGUISHING MEDIA: Water.
SPECIFIC FIRE HAZARDS: None known.
FIRE FIGHTING PROCEDURES: Wear full protective clothing including helmet, self contained, positive pressure or pressure
demand breathing apparatus, bunker coat and pants, bands around arms, waist, and legs,
face mask, and protective covering for exposed areas of the head. Water may not effectively
extinguish fire; however, it should be used to keep fire-exposed containers and surfaces
cool and prevent explosive rupture. If large amount is involved, evacuate area.
FLASH POINT (SETAFLASH): 63掳C (145掳F)
FLAMMABILITY LIMITS IN AIR (XYLENE): LEL: 1%

ENGINEERING CONTROLS:
LOCAL EXHAUST: Recommended
GENERAL VENTILATION: Recommended

PERSONAL PROTECTIVE EQUIPMENT:
EYE PROTECTION: Avoid eye contact. Use proper protection - safety glasses as a minimum.
SKIN AND BODY PROTECTION: Avoid skin contact. Protect hands with impervious rubber gloves and wear typical full cover
clothing. Gloves must be checked before each use for signs of degradation and
penetration and for proper functioning. Wear appropriate gloves when handling this
product.
RESPIRATORY PROTECTION: Avoid breathing of vapors. Wear appropriate, properly fitted NIOSH/MSHA approved
respirator when the airborne contaminant levels exceed the exposure limits indicated on
the MSDS. Follow respirator manufacturer鈥檚 directions for respirator use.
Industrial hygiene personnel can assist in judging the adequacy of existing engineering
controls.
HYGIENE MEASURES (INGESTION): Wash hands after handling and before eating.
PRECAUTIONARY MEASURES: Avoid eye contact. Avoid skin contact. Avoid breathing vapor. Keep container closed. Do
not take internally.

Note: These precautions are for room temperature handling. Use at elevated temperatures or aerosol spray applications may
require added precautions.
