• Preheat isocyanate ho 23 - 30°C ha e ka bolokoa ka tlase ho 20°C.

• Preheat polyol le karolo ea C ho ea ho 40°C pele u sebelisa.Hoa hlokahala ho hlohlelletsa polyol ho fihlela 'mala le likarolo li fetoha homogeneous.

• Leka likarolo ho ea ka karolelano ea ho kopanya, kenya isocyanate ka senoelo se ka holimo, eketsa karolo ea C ho polyol ho premix.

• Tšela isocyanate ka polyol (e nang le Karolo ea C) 'me u kopanye metsotso e 1 - 2 ka mor'a ho ntša metsi ka metsotso e 10 ka ho arohana.
