<p>Process for the electron beam curing of coating compositions : The electron beam curing of ethylenically unsaturated coating compositions can be accelerated by the addition of sterically hindered amines. These amines are at the same time light stabilisers for the cured coating. 2,2,6,6-Tetra-alkylpiperidine derivatives are examples of such amines. If a UV absorber is added to the coating compositions in addition, a synergistic increase in the light-stabilising effect occurs.</p> |
