| 摘要 |
<p>The invention concerns storage-stable compositions resulting from a hydroxylated urethane prepolymer and a mixture of monomer and acrylate oligomers, capable of yielding, by thermal of photochemical radical polymerisation, an elastomer; the urethane prepolymer being obtained by condensation of a conjugate diene oligomer with hydroxylated termination, optionally mixed with a chain extender, with a polyisocyanate compound. Said compositions are useful for protecting electric and/or electronic components and generally for coating metal or plastic material surfaces.</p> |
