Abstract

The invention relates to cast resins containing A) at least one solid unsaturated polyester and B) at least one oligomer and/or polymer cross-linking agent that can be copolymerised therewith, said cross-linking agent having at least one terminal and/or lateral propenyl-, isoprenyl- and/or (meth)acrylester group in relation to the oligomer- and/or polymer main chain. The invention also relates to the use of cast resins as casting beans and impregnants and as coating agents. The invention further relates to a method for melt impregnating or melt coating components, absorbent mattes or grounded or ungrounded substrates with the cast resins.
