    • A process for the production of multi-layer coatings, comprising the successive steps: 1) applying a 10 to 35 µm thick base coat layer onto a substrate provided with an EDC primer, 2) applying a clear coat layer onto the base coat layer, 3) jointly curing the base coat and clear coat layers, wherein the base coat layer is applied in a first layer and in a second layer; the first layer comprises a modified water-borne base coat produced by mixing an unmodified water-borne base coat with a pigmented admixture component and the second layer comprises the unmodified water-borne base coat, wherein the admixture component contains at least one polyisocyanate, has a ratio by weight of pigment content to resin solids content of 0.05:1 to 0.5:1 and is mixed into the unmodified water-borne base coat in a ratio by weight of 0.2 to 1 parts of polyisocyanate : 1 part of resin solids of the unmodified water-borne base coat, and wherein the pigment content of the admixture component comprises at least one pigment which effectively reduces UV transmission and wherein the pigment content is made in such a way that UV light can penetrate through the base coat layer formed from modified water-borne base coat and unmodified water-borne base coat only in accordance with a UV transmission of less than 0.1% in the wavelength range of from 280 to 380 nm and of less than 0.5% in the wavelength range of from 380 to 400 nm.
    • 一种制备多层涂层的方法,包括以下连续步骤:1)在具有EDC底漆的基材上施加10至35μm厚的底涂层,2)在底涂层上施加透明涂层, 3)共同固化底涂层和透明涂层,其中底涂层施加在第一层和第二层中; 第一层包括通过将未改性的水性底涂层与着色混合物组分混合而制备的改性水性底漆,第二层包含未改性的水性底涂层,其中所述混合物组分含有至少一种多异氰酸酯,具有 颜料含量与树脂固体含量的重量比为0.05:1至0.5:1,并以未改性的水性底涂层以0.2至1份的多异氰酸酯的重量比混合:1份 未改性的水性底涂层,并且其中所述混合物组分的颜料含量包含至少一种有效降低UV透射的颜料,并且其中所述颜料含量以这样的方式制备,使得UV光可以穿透由经修饰的基底涂层形成的底涂层 水性底涂层和未改性水性底涂层,仅在280〜380nm的波长范围内小于0.5的紫外线透射率小于0.5% 在380至400nm的波长范围内的%。

    • This invention relates to a solvent based high solids thermosetting coating composition having a low volatile organic content (VOC content) useful in the manufacture of automobiles and trucks comprising a film-forming binder, characterised by the inclusion in the binder of an addition-polymerizable ethylenically unsaturated compound and an effective amount of thermal free radical initiator to effect polymerization of the addition-polymerizable component using heat. The addition- polymerizable compound serves a dual function of solvent and auxiliary crosslinking agent for the coating system to deliver low VOC and desired rheological and physical properties These coatings are especially useful in reducing emissions, while also meeting today’s performance requirements for automotive topcoats, such as ease of application and excellent durability and appearance. No actinic radiation is need.

These coatings are especially useful in reducing emissions, while also meeting today's performance requirements for automotive topcoats, such as ease of application and excellent durability and appearance. No actinic radiation is needed to effect polymerization of the addition-polymerizable compound. This is an advantage for coatings that are applied to three-dimensional objects such as vehicle bodies or parts thereof.
