    • The present invention is directed to a coating powder base composition having a viscosity of between about 2 to about 85 Pa · s. Such composition can be produced in large batches and then smaller portions of such batches can be mixed with various tinting agents to obtain a desired coating powder color. The desired viscosity may be obtained through incorporation of a resin modifying agent. The invention also includes methods for making such base compositions and resultant coating powders as well as for coating substrates using such coating powders. Finally, two or more resinous base compositions maybe mixed with a tinting agent to obtain a desired gloss and color.
    • 本发明涉及粘度在约2-约85Pa·s之间的涂料粉末基础组合物。 这样的组合物可以批量生产,然后将这些批次的较小部分与各种着色剂混合以获得所需的涂料粉末颜色。 所需的粘度可以通过加入树脂改性剂获得。 本发明还包括制备这种基础组合物和所得涂层粉末以及使用这种涂层粉末涂覆基底的方法。 最后,将两种或更多种树脂基组合物与着色剂混合以获得所需的光泽和颜色。
