Dual Valve PU Foam
Sealants & Silicones
Selsil Dual Valve PU Foam is a single-component filling and insulation material, polyurethane based, that cures with the moisture in the air. Selfoam Dual Valve PU Foam is designed with a special valve that provides many application advantages.
The application surface must be clean, dry, dust-free and free of grease. If necessary, it should be moistened by spraying water. The optimum application temperature is 20–25 °C. Cold cans should be kept at room temperature for 20 minutes. Before use, the can should be shaken 30 times. Foam output can be controlled by valve pressure. For the highest yield, the valve should be held facing downward. The valve is designed to work in every direction.
Uncured foam can be cleaned with Selsil Foam Cleaner. Cured foam must be cleaned mechanically.
12 months when stored upright between +5 °C and +25 °C.
Refer to the current Safety Data Sheet for safe use and disposal.
