UNSATURATED POLYESTER RESIN SYSTEMS WITH LATENT THICKENING TENDENCY

The invention relates to a two- or multi-component system having: at least one polyester component 1 which comprises: i) at least one unsaturated polyester; ii) at least one ethylenically unsaturated monomer; iii) at least one inorganic thickener (a1); and iv) at least one wetting- and dispersing ag...

Beschreibung
Zusammenfassung:	The invention relates to a two- or multi-component system having: at least one polyester component 1 which comprises: i) at least one unsaturated polyester; ii) at least one ethylenically unsaturated monomer; iii) at least one inorganic thickener (a1); and iv) at least one wetting- and dispersing agent (a2) that inhibits the thickening action of the inorganic thickener (a1); and at least one initiator component 2 which i) comprises at least one component (b1) that is able to at least partly neutralise the inhibition of the thickening action of the inorganic thickener (a1) and ii) at least one initiator that is able to trigger the polymerisation of components (i) and (ii) of the polyester component 1. The wetting- and dispersing agent (a2) is non-reactive in relation to components (i) and (ii) of the polyester component 1. The invention also relates to substrates coated with a two- or multi-component system according to the invention. The invention further relates to the use of a combination of (a1) and (a2) in formulations containing unsaturated polyesters, in order to provide said formulations with a latent thickening effect.
