Application
During the application, the ideal packaging temperature should be +20°C and the ambient temperature should be between +5°C and +30°C. Before use, hold the can horizontally and shake well. Insert the straw into the valve. Use the foam by pressing the valve with the can upside down. Wetting the foam after application reduces the curing time and increases the bond strength.
