| Desmodur E 23 A is an aromatic polyisocyanate prepolymer based on diphenylmethane diisocyanate (MDI). It is suitable as a binder for the formulation of moisture-curing, one-component coatings and adhesives. It is also suitable as a hardener for hydroxyl-bearing co-reactants. Properties / Applications: Desmodur E 23 A 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. Coatings formulated with Desmodur E 23 A are used as highgrade anti-corrosion systems for steel in civil and hydraulic engineering applications. In combination with suitable Desmophen polyols, Desmodur E 23 A yields tough but flexible, wear-resistant coatings and sealers. Desmodur E 23 A is also suitable for use in the formulation of solvent-free moisture-curing one-component adhesives or in combination with Baycoll to formulate two-component adhesives. These can be used to bond many materials, e.g. wood, metal and plastic. As with any product, use of Desmodur E 23 A in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
