No universal specific antidote is available for a proprietary polyether urethane amine mixture.
Consider possible corrosive injury, aspiration risk, respiratory irritation, and delayed allergic sensitization.
HANDLING AND STORAGE
Handling:
Use chemical-resistant gloves, protective clothing, and tightly fitting chemical safety goggles.
Use a face shield where splashing or pressurized transfer may occur.
Avoid direct contact with the skin, eyes, and clothing.
Avoid breathing vapors, aerosols, and mists during transfer, mixing, and application.
Do not eat, drink, or smoke in areas where ARADUR 70 is handled.
Ventilation:
Provide effective general ventilation in storage and processing areas.
Use local exhaust ventilation at mixing, dispensing, filling, and application points.
Keep airborne exposure below applicable occupational exposure limits.
Use suitable respiratory protection when engineering controls are insufficient.
Prevent vapors and aerosols from accumulating in confined or poorly ventilated areas.
Storage:
Store ARADUR 70 in its tightly closed original container.
Keep ARADUR 70 in a cool, dry, and well-ventilated location.
Protect ARADUR 70 from moisture, atmospheric carbon dioxide, direct sunlight, and contamination.
Store ARADUR 70 away from strong acids, strong oxidizing agents, and incompatible reactive chemicals.
Maintain the storage temperature specified in the current Huntsman product documentation.
Spill and Leak Procedures:
Evacuate unnecessary personnel and ventilate the affected area.
Wear suitable chemical-resistant protective equipment before approaching the spill.
Contain the liquid with sand, earth, vermiculite, or another compatible non-combustible absorbent.
Collect the absorbed material in a closed and correctly labeled recovery or waste container.
Prevent ARADUR 70 from entering drains, sewers, soil, groundwater, and natural waterways.
Handling Precautions:
Review the latest regional safety data sheet before receiving, transferring, mixing, or applying ARADUR 70.
Ensure that eyewash stations and emergency safety showers are immediately accessible.
Use dedicated, clean, dry, and chemically compatible transfer equipment.
Never return contaminated or resin-mixed material to the original ARADUR 70 container.
Dispose of unused product, contaminated absorbents, cured residues, and packaging according to applicable regulations.
