5. Hanlding
Contact with skin and eyes must be avoided. Safety goggles, protective gloves and overalls must be worn when working with these chemicals.

 
6.Storage

The materials are sensitive to humidity and partially used drums should be tightly sealed to prevent the ingress of moisture.

(Polyol Blend)
The Polyol blend has a shelf life of three to six months from date of manufacture when stored indoors at temperatures of 20-30°C. The Polyol blend is recommended thoroughly mixed before using.

(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 solids may occur).
