Abstract
Compositions, which are stable on storage, which make it possible to obtain elastomer coatings. The compositions are obtained from a hydroxylated urethane prepolymer and from a mixture of acrylate monomer and oligomers, capable of giving an elastomer by thermal or photochemical radical polymerization; the urethane prepolymer being obtained by condensation of a conjugated diene oligomer comprising hydroxylated endings, optionally mixed with a chain extender, with a polyisocyanate compound. These compositions can be used in the protection of electrical and/or electronic components and generally as coatings for metal surfaces or for plastic surfaces.
