Mixing scheme and process for the preparation of a refinish coating composition |
摘要 |
The present invention refers to a mixing scheme containing a plurality of pigmented base paint compositions having defined colors and optionally one or more non-pigmented base paint compositions comprising at least one rheology controlled base paint composition containing at least one pigment selected from the group consisting of inorganic pigments, di-keto-pyrrolo-pyrrole type pigments, organic liquid crystal type pigments and carbon black and having the following rheology profile (1) an initial viscosity V1 at 20 DEG C of 65 Pa s or greater when measured at a shear rate of 10<-3> s<-1>, (2) a viscosity V2 at 20 DEG C when measured at a shear rate of 10<-3> s<-1> immediately after subjecting to a shear rate of at least 15 s<-1> whereby the viscosity V2 is 700 Pa s or less and is less than or equal to 70 % of V1; (3) 24 hours after subjected by shaking to a shear rate of at least 15s<-1> a viscosity V3 at 20 DEG C of at least 140 % of V2 and be at least 55 Pa s, to a process of preparing a refinish coating composition using the mixing scheme of the present invention, to a refinish coating compositions obtainable therefrom, to a process of coating a substrate using the refinish coating composition and to a coated substrate obtainable therefrom.
