DESMODUR® E 21
Desmodur® E 21 is an aromatic polyisocyanate prepolymer based on diphenylmethane diisocyanate (MDI). It is a solvent-free liquid of medium viscosity. It is suitable for use in the formulation of moisture-curing, one-component systems which, when thinned with a suitable solvent, can be used as 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.
