Before use, the component A must be homogenized, as additives tend to cause phase separation.
The density of the material can be adjusted to the processing specification of 0.90 – 1.00 g/ml by adding dispersed air through stirring. The air helps to ensure a uniform foam structure.
The component B is very sensitive to moisture and must not be stirred. Due to its high reaction rate, the system is usually processed by two-component mixing and dispensing machines.
