Process for coating moulded objects made of a fibreglass- reinforced polyester (FRP), using a mould coating composition that consists of the following: a) a crosslinkable liquid composition with an average molecular weight of up to about 5000 and having a plurality of polymerizable ethylenic double bonds, which composition is essentially free both of active hydrogen atoms and of isocyanate groups, and b) a material chosen from a group comprising I) a polyisocyanate and II) a reaction product formed from an equivalent excess of a polyisocyanate and an ethylenically unsaturated compound with -NH2, -NH- and/or OH groups, this reaction product being free of active hydrogen atoms. The invention also covers a composition for use as a mould coating material in the mould lining process, where the material has the above composition. |
