    摘要： 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.

    摘要翻译： 本发明提供了一种用可焊接底漆涂覆金属基材和至少一种粉末涂料的方法。 基础粉末涂料含有当粉末涂料被加热时平行于表面排列的片状颜料。 任选地，在基底粉末涂层上施加透明顶涂层。 还提供了通过涂覆方法涂覆的基材。 涂覆方法允许用可焊接底漆涂覆的基材通过焊接组装成组件或成品部件，然后涂覆粉末底漆和透明涂层。 制备的零件具有惊人的视觉效果和性能，与传统的汽车零件相当，但更有效和经济地制备。

    摘要： Disclosed are thermosetting compositions which are comprised of a resinous phase dispersed in an aqueous medium, the resinous phase comprising (a) an ungelled active hydrogen group-containing polymer which contains amine salt groups, the polymer having been prepared by atom transfer radical polymerization in the presence of an initiator having at least one radically transferable group, and (b) a curing agent having at least two functional groups which are reactive with the active hydrogen groups of (a). The active hydrogen group-containing polymers of the thermosetting compositions, which are prepared by atom transfer radical polymerization, have narrow molecular weight distributions and well-defined, specifically tailored polymer architecture which can provide enhanced crosslink density and dispersibility of the thermosetting compositions. Also disclosed is a method of electrocoating a conductive substrate using the thermosetting compositions of the invention, and a substrate coated by this method.

    摘要： An electrodepositable composition that has: (A) an active hydrogen-containing cationic resin, electrodepositable on a cathode, having: (1) a polyepoxide; (2) an oxygen-substituted diamine compound having the following formula: ##STR1## where n is an integer from 2 to 4; and where R.sup.1 or R.sup.2 are the same or different and either one or both contain at least one oxygen and are alkyl, cycloalkyl, substituted alkyl, or substituted cycloalkyl having from 1 to 6 carbon atoms, or R.sup.1 and R.sup.2 are alkanol groups having from 2 to 6 carbon atoms, or R.sup.1, R.sup.2, and the N atom form a cyclic group which is substituted or unsubstituted such as morpholine and 1-(3-aminopropyl) imidazole; and (B) at least partially blocked isocyanate or polyisocyanate curing agent. The diamine compound of Formula I can be used alone or in conjunction with one or more secondary amines, nonhydroxy group containing amines and/or amines with ring structures. Optionally, the polyepoxide can be chain extended with active hydrogen-containing compounds other than polyoxyalkylene polyamines. Also provided is a method of producing an active hydrogen-containing cationic resin composition, electrodepositable on a cathode, comprised of (a) mixing together in a suitable reaction vessel a polyepoxide, or the precursors of the polyepoxide, a polycarboxylic acid, a blocked isocyanate curing agent; (b) adding to the mixture of (a) a base catalyst and the diamine compound of Formula I; (c) polymerizing the mixture of (b) to form a resinous composition; and (d) neutralizing the resinous composition of (c) by adding the resinous composition to a dilute mixture of acid and water to form an aqueous dispersed electrodepositable cationic resin composition.
