Beschreibung
Zusammenfassung:	Storage-stable two-component polyurethane or polyisocyanurate spray foam compositions are disclosed, said compositions comprising: (a) an A-side component comprising one or more polyisocyanate and one or more catalyst; and (b) a B-side component comprising one or more polyol; and further comprising one or more hydrohaloolefin blowing agent in either the A-side component or the B-side component, or in both; wherein both the A-side component and the B-side component, separately, generate less than 600 ppm of fluoride ion after two weeks of aging at 50 °C. L'invention concerne des compositions de mousse de pulvérisation de polyuréthane ou de polyisocyanurate à deux composants stables au stockage, lesdites compositions comprenant : (a) un composant côté A comprenant un ou plusieurs polyisocyanates et un ou plusieurs catalyseurs ; et (b) un composant côté B comprenant un ou plusieurs polyols ; et comprenant en outre un ou plusieurs agents d'expansion hydrohalooléfine dans le composant côté A ou le composant côté B ou dans les deux ; le composant côté A et le composant côté B, séparément, générant moins de 600 ppm d'ion fluorure après deux semaines de vieillissement à 50 °C.
