STORAGE OF MATERIALS
The materials are sensitive to humidity and partially used drums should be tightly sealed to
prevent the ingress of moisture.
ZHD-8007CP-A (Polyol Blend)
The Polyol blend has a shelf life of three months from date of manufacture when stored indoors
at temperatures of 20-30°C. The Polyol blend should be thoroughly mixed before use.
ZHD-8007CP-B (Isocyanate)
The Isocyanate has a shelf life of one year from date of manufacture when stored indoors at
temperatures of 20-30°C. Avoid storage temperatures of below 0°C (as some crystallization
may occur) or above 50°C (as formation of insoluble so lids may occur).
SAFTY PRECAUTIONS
Direct contact with ZHD-8007CP can lead to moderate eye irritation and mild skin irritation, which can cause skin allergies. Repeated inhalation of high concentration of volatile gas will cause respiratory allergy, and should be treated immediately. Anti- inflammatory and anti-allergic treatment measures should be taken. Please be careful in the operation to prevent contact with the skin and splash into the eye, please wear the necessary protective equipment (gloves, protective goggles, working clothes, etc.). Once splashed on the skin or the eye, rinse with water immediately for at least 15 minutes, and the skin is washed with soapy water. Please seek medical treatment immediately after swallowed.
