Abstract:
A method of coating a substrate comprising:adding an organic solvent and a non-volatile aliphatic polyether to a higher-viscosity basecoat composition so as to produce a lower-viscosity basecoat composition, said higher-viscosity basecoat composition being suitable for producing a polyether-free, lower-viscosity basecoat composition and said non-volatile aliphatic polyether containing at least one hydroxyl group per molecule, having a mean molecular weight not less than about 300 and being present in an amount from about 6 to about 10 weight percent of the total weight of the volatile and non-volatile components; applying the polyether-containing, lower-viscosity basecoat composition to a substrate; allowing a flash-off period to occur without baking; overcoating the coated substrate with a clearcoat; and baking the overcoated substrate to produce a multicoat finish such that said finish has a metallic appearance equal to that of a metallic finish prepared from the polyether-free, lower-viscosity basecoat composition.
