OptiCoat Jet coating
Uniform and skipfree jet coating
OptiCoat Jet coating provides very uniform and skipfree coating quality. It gives the best possible surface smoothness compared to any other coating method. OptiCoat Jet coating station applies a surplus coating layer to paperboard surface with jet nozzles. The excess coating is scraped away by metering blade and returned on a return plate to the color collection pan. The desired coatweight is achieved by adjusting the angle or pressure of the blade. The impingement pressure is maximized with closed nozzle geometry.

Uniform coating quality
OptiCoat Jet produces high quality coating on paper and board in both cross and machine direction. High quality backing roll is one of the reasons for reduced MD coatweight variation. Skipfree coating is a result of a very effective de-aeration in color circulation. The application method and cross direction control capabilities are important for uniform application and excellent CD profiles.

All Valmet coating stations are fully pretested in workshop. The instrumentation and controls are integrated in the machine and all the controls located by the station frame.
