How do I use Purmolproducts in my polyurethane?

Purmol powder in one-component systems should be added prior to the addition of the prepolymer. In two-component systems, we recommend the addition of 2.5 wt% – 5 wt% Purmol powder to the polyol component. This must be stirred thoroughly to allow time for the Purmol powder to adsorb the water before the addition of the isocyanate.
