| abstract |
The invention relates to a two-component or multi-component system comprising: at least one polyol component 1 having: i) at least one polyol, ii) at least one inorganic thickener (a1 ), and iii) at least one wetting and dispersing agent (a2), which inhibits the thickening effect of the inorganic thickener (a1); and at least one polyisocyanate component 2 comprising: i) at least one polyisocyanate; wherein (A) the polyisocyanate component 2 comprises at least one component (b1) which at least partially counteracts the inhibition of the thickening effect of the inorganic thickener (a1); and/ or (B) at least one isocyanate-free component 3 comprises at least one component (b1) which at least partially counteracts the inhibition of the thickening effect of the inorganic thickener (a1); the wetting and dispersing agent (a2) is non-reactive to said at least one polyol, and said polyisocyanate component 2 is reactive to said polyol component 1 . The invention also relates to a substrate coated with the system according to the invention, together with at least one inorganic thickener (a1) and at least one wetting and dispersing agent (a2) which suppresses the thickening effect of said inorganic thickener (a1) ) for the application of providing a potential thickening effect to a composition containing at least one polyol. |
