METAL SURFACE COATING PROCEDURE USING A POWDER PRIMER AND A TOP COAT APPLIED BY METTING, POWDER PRIMER COMPOSITE UTILIZED AND COMPOSITE MATERIALS PRODUCED THEREOF

摘要

process for coating metal substrateswith the help of a grip and a primary coatingpolyamide based skin and / or polyu00e9theresteramide.characterized in that it comprises the following steps: (a)coating of substrate with one or more layers ofthe primary adhesion of resin based powderaccording to the technique of application of thermosetting(b) heating the substrate powder, and immediately and inapplication: (c) by soaking in a fluidized bed ofpowder coating on the surface of polyamide based and / orpolyu00e9theresteramide. the invention also concernspowdered compositions usable as a primaryadhesion of composite materials, as well as the substrate.primary adhesion and metal / coating on the surface. thethis invention is in the field of coatingsthe metal substrate is applied by dipping.
