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.

Melt coating method using a polyester resin composition

The method for hardening electro-insulating materials is characterised by the utilization and/or co-utilization of near-infrared radiation (NIR) having a wavelength of 500 nm to 1400 nm. NIR also enables very fast hardening of the component surface even with pure thermally hardenable impregnating material and further provides good hardening of thick layers located deep inside said layers. Combined hardening, for example, NIR and UV light, is also possible.
