    Abstract: The lacs are appropriate for the cataphoretic deposit of a coating on electrically conducting substrates used as cathodes. They are prepared with 5 - 35% by weight at least of an epoxy resin, 2 - 20% by weight at least of a ketonic and/or hydrocarbonated resin, 15 - 60% by weight at least of a cationic synthetic resin with functional groups, present with a concentration of 10-70% as a dispersion or solution, 5 - 30% by weight at least of an organic cross-linking agent, solid at room temperature and 0 to 70% by weight of pigments and/or additives. All these compounds are mixed in a ground aggregate state, in one or a plurality of steps, one step at least occuring in a wet medium, so as to form an homogeneous lac which has a particle size of less than 100, preferably less than 15 //cm. The mixture is then brought with water at a solid particle content required by a substrate which is preferably comprise between 1 and 30% by weight. The method allows to obtain a good homogeneity of the particles and thereby a uniform thickness of the coating layer exhibiting a particularly high resilience resistance.

    Abstract translation: lac适用于在用作阴极的导电衬底上的涂层的阴极沉积。 至少一种环氧树脂为5-35重量％，至少为酮和/或烃基树脂为2-20重量％，至少为官能团的阳离子合成树脂为15-60重量％ ，作为分散体或溶液的浓度为10-70％，至少有机交联剂为5-30重量％，室温为固体，颜料和/或添加剂为0〜70重量％。 所有这些化合物在一个或多个步骤中以研磨聚集状态混合，至少在湿介质中发生一步，以便形成粒径小于100，优选小于15的均匀的lac //厘米。 然后将混合物带入基质所需的固体颗粒含量的水，其优选包含1至30重量％。 该方法允许获得良好的颗粒均匀性，从而获得显示出特别高的耐回弹性的涂层的均匀厚度。

    Abstract: The invention provides a process for the manufacture of a polyethylene wax micro-powder, 99 weight % of which has a grain size of less than 15 microns, for the dulling of varnishes. Such a micro-powder generally cannot be obtained without difficulty by grinding; in accordance with the invention this is possible, however, by grinding the polyethylene wax together with an amide wax.
