SAFETY AND HANDLING
For industrial use only by professional, trained painters. Not for sale to or use by the general
public. Before using, read and follow all label and MSDS precautions. If mixed with other
components, mixture will have hazards of all components.
Ready to use paint materials containing isocyanates can cause irritation of the respiratory
organs and hypersensitive reactions. Asthma sufferers, those with allergies and anyone with
a history of respiratory complaints must not be asked to work with products containing
isocyanates.
Do not sand, flame cut, braze or weld dry coating without a NIOSH approved air purifying
respirator with particulate filters or appropriate ventilation, and gloves.
