PROCESS FOR PREPARING MULTI-LAYER COATINGS ON AUTOMOTIVE BODIES OR AUTOMOTIVE BODY PARTS |
摘要 |
<p>A process for preparing a multi-layer coating on an electrically conductive automotive body or an electrically conductive automotive body part by applying a cathodic electrodeposition coating layer, optionally a further coating layer and an outer clear coating, in which the cathodic electrodeposition coating layer of a cathodic electrodeposition coating composition is applied which, as the cathodic electrodeposition binder, contains a seed polymer with an amine value of 30 to 100 mg KOH/g and a hydroxyl value of 50 to 200 mg KOH/g, which can be prepared by radical polymerisation of 70 to 97 wt-% of a monomer mixture comprising hydroxy-functional olefinically unsaturated monomer and amino-functional olefinically unsaturated monomer in the presence of 3 to 30 wt-% of an aminoepoxy resin.</p> |
