一般特征
Imprafix 2794 is a waterbased aliphatic blocked polyisocyanate.
Imprafix 2794 is crosslinker with improved reactivity and thermostability (yellowing). In combination with Bayhydrol® polyols Imprafix 2794 can be used for the formulation of water-reducible, lightfast one-component polyurethane baking coatings and as an additive in waterborne baking systems to improve flexibility, impact strength and adhesion.
