Sometimes you need more than one coating layer applied with more than one coating type of a coating head to achieve the optimal results. In the following image you can see the different kinds of benefits of two different coating methods: blade coating and curtain coating. Blade coating improves smoothness and curtain coating improves coating coverage - together they delvier immaculate coating quality!
Profile variation with different coating methods is quite big. It goes hand in hand with the previous example of combining different coating methods. Peak-to-peak coat weight variation has a great effect on the prinnting quality in the later stages of the process. Let our experts help you choose the best solution for you!
