⚠️ WARNING
🚨 DANGER
⚠️ Critical Safety Information
Persons With Known Respiratory or Allergy Problems Must Not Be Exposed to This Product.
⚠️ Hazard Statements
- May cause skin irritation, reddening, dermatitis and sensitization with prolonged exposure
- May cause irritation, inflammation and damage to sensitive eye tissue
- May cause irritation of eyes, upper respiratory tract and lungs
- Chronic exposure may cause isocyanate sensitization (chemical asthma) - effects may be permanent
Skin Contact
No irritation likely from short contact. Prolonged/repeated exposure can cause skin irritation, reddening, dermatitis and sensitization. May stain skin.
Eye Contact
As liquid or dust may cause irritation, inflammation and damage to sensitive eye tissue. Corneal injury is unlikely.
Ingestion
Single dose oral toxicity is extremely low. Can result in irritation and corrosive action in mouth, stomach and digestive tract.
Potential Health Effects
At room temperature, MDI vapors are minimal. Heating, foaming or dispersing operations may generate more vapor. Severe overexposure may lead to pulmonary edema.
Carcinogenicity: MDI and polymeric MDI are not listed by the NTP, IARC or regulated by OSHA as carcinogens. Current exposure guidelines are expected to protect against effects observed in animal studies.

👁️ Eyes
Flush eyes with plenty of water for at least 15 minutes. Materials containing MDI may react with eye moisture forming thick material difficult to wash away. Seek medical attention.
🖐️ Skin
Wash off in flowing water or shower. Remove and wash contaminated clothing, discard contaminated shoes. Seek medical attention if redness, itching or burning develops or persists.
🍽️ Ingestion
If swallowed, rinse mouth with water. Give 1 or 2 glasses of water to drink. Do not induce vomiting. Seek immediate medical attention. Never give anything by mouth to unconscious person.
💨 Inhalation
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, oxygen should be administered by qualified personnel. Call physician or transport to medical facility immediately.
⚠️ Important Application Note
This material is designed and intended to be pumped, not sprayed. MDI becomes more hazardous when atomized (sprayed). Harmful if inhaled. Toxic fumes are released in fire situations.
Fire Degradation Products: Toxic fumes are released in fire situations. Combustion may produce carbon dioxide, carbon monoxide and nitrogen oxides.
Extinguishing Media: Use dry chemical foam, carbon dioxide, halogenated agents or water.
Protective Equipment: Wear positive pressure self-contained breathing apparatus with full face piece and full protective clothing.
Spill Response
Evacuate spill area. With adequate ventilation and appropriate PPE, cover area with inert absorbent (clay or vermiculite) and transfer to metal waste containers.
⚠️ Important Note
Isocyanate will react with water and generate CO2. This could result in rupture of any closed container.
Clean Up Solution: 5-10% sodium carbonate and 0.5% liquid detergent in water, or 3% concentrated ammonium hydroxide and 0.5% liquid detergent in water. Use 10 parts solution to 1 part spilled material. Allow to stand 48 hours.
Do not heat or cut empty containers with electric or gas torch.
Storage
Store between 60°F and 85°F (15°C - 30°C) in sealed containers. Typical shelf life is 6 months or more from date of manufacture. Should freezing occur, material must be thawed thoroughly and mixed until uniform.
Handling
Use PPE when transferring material. Safety glasses and gloves are minimum protection. The reaction of polyols and isocyanates generates heat - contact with skin or eyes can cause severe burns.
Exposure Limits: Keep airborne isocyanate level below TLV 0.005 ppm TWA (ACGIH) and PEL 0.02 ppm ceiling (OSHA). These limits do not apply to previously sensitized individuals or those with existing respiratory disease.
Ventilation
MDI has very low vapor pressure at room temperature. General/local ventilation typically controls exposure adequately.
Respiratory Protection
Supplied air, full face piece, positive pressure respirator required when concentrations unknown or exceed threshold. Air purifying (cartridge type) respirators NOT approved for isocyanates.
Eye Protection
Chemical splash goggles, safety glasses or full face shield.
Protective Clothing
Wear clothing and gloves impervious to MDI: butyl rubber, nitrile rubber, neoprene, Saranex coated Tyvek.
Boiling Point
406°F @ 5mm Hg
Vapor Density
1.5 (MDI) AIR=1
Vapor Pressure
< 10⁻⁵ mm Hg
Evaporation Rate
Slower than ethyl ether
Solubility
Reacts slowly, liberates CO2
Stability
Polyisocyanates are highly reactive chemicals. Stable when stored in sealed containers under normal conditions. Avoid extended exposure over 110°F (45°C).
Hazardous Polymerization
May occur with incompatible reactants, strong bases, water, or temperatures over 320°F (160°C). May rupture closed containers.
Reactivity
Reacts with water, acids, bases, alcohols, metal compounds. Reaction with water is slow under 102°F (50°C) but accelerates at higher temperatures.
