Desmodur® E XP 2723 is an aromatic polyisocyanate prepolymer based on diphenylmethane diisocyanate (MDI) that is a binder for the formulation of moisture-curing, one-component coatings and adhesives and as a hardener for hydroxyl-bearing co-reactants. This product has an NCO content of approx. 15.4%, a flash point of approx. 223°C, and a density at 20°C of approx. 1.12 g/ml.
Desmodur® E XP 2723 is suitable for use in the formulation of moisture-curing one-component systems which, when thinned with a suitable solvent, can be used as a primers and sealers for porous substrates to provide protection against moisture, oil, fuel and other chemicals. It can also be used as a binder in the formulation of synthetic resin mortars. In combination with suitable Desmophen® polyols, Desmodur® E XP 2723 yields tough but flexible, wear-resistant coatings and sealers.
