Pulverulent polyamide coating compositions wherein the polyamide has as an average at least nine carbon atoms per carbonamide group |
摘要 |
Pulverulent polyamide coating compositions consisting of a mixture of similar polyamides having on the average at least nine aliphatically bound carbon atoms per carbonamide group and of different relative viscosity, the difference in relative viscosities amounting to at least 0.04 and at most 0.1 units. The mixtures are obtained by mixing powders prepared both by precipitation or by cold grinding or also by mixing the corresponding granulates which subsequently are then cold ground.
