Desmophen® 4050E-LY
A amine-based tetrafunctional polyether polyol for the production of rigid polyurethane foams. Due to its high basic reactivity, it is particularly suitable for the formulation of polyol systems for use in continuous lamination (e.g. the continuous production of sandwich panels) and for spray applications. Hydroxyl Number approx. 630 mg KOH/g
