A process for applying a two-tone color effect coating to a substrate including applying an accent powder basecoating composition including film-forming material; reaction product as described herein; flow control agent; and first color effect additive, to a first predetermined portion of a surface of a substrate; at least partially curing the accent basecoating; applying a main liquid or powder basecoating composition having a different color effect additive to a second predetermined portion of the substrate, such that a portion of the accent basecoat is not contacted by the main basecoating composition; at least partially curing the main basecoating composition; applying a topcoating composition over the accent basecoat and main basecoat and curing the resulting composite coating, such that the first portion of the substrate has a different color effect than the second portion of the substrate to provide a two-tone color effect coated substrate.

Two-tone color effect coating process

A method of forming a composite coating is provided including (a) applying a first powder base coating to a substrate; and (b) either (1) applying a second powder base coating comprising flake or platelet effect pigment and heating the first and second base coats to substantially level the second base coat and allow migration of the effect pigment to a surface region thereof but not sufficient to cause the second base coat to cure; and (2) applying a top coating and substantially curing the resultant composite coating; or alternatively, (3) heating the first base coat to form a generally continuous film; (4) applying the second powder base coating comprising the effect pigment and heating the second base coat to substantially level the second base coat and allow migration of the effect pigment to a surface region thereof; and (5) applying the top coating and substantially curing the resultant composite coating.

Methods of forming composite coatings

A transportable container for fluidizable solids includes a storage container adapted to contain the fluidizable solids is disclosed. The storage container defines an air inlet port for introducing fluidizing air into the storage container and a solids outlet port for discharging the solids from the storage container. A solids outlet conduit may be connected to the solids outlet port for supplying the solids to a downstream process or apparatus. An agitator is provided at the bottom end of the storage container for mixing and maintaining homogeneity of the solids in the fluidizing air. A fluid permeable fluidization membrane is disposed in the storage container below the agitator. The fluidization membrane defines an air chamber below the solids for introducing the fluidizing air into the solids.

Transportable container for fluidizable material and method

A method of coating metallic substrates with weldable primer and at least one powder coating is provided by the present invention. The base powder coating contains flake pigments that align parallel to the surface when the powder coating is heated. Optionally, a clear top coating is applied over the base powder coating. Substrates coated by the method of coating are also provided. The method of coating allows substrates coated with weldable primer to be assembled into assemblies or finished parts by welding, and then to be coated with the powder basecoat and clear coat. The parts prepared have striking visual effects and performance comparable to conventional automotive parts but are prepared more efficiently and economically.
