Gravure and Rotary Coating Systems
category
Gravure and rotary coating systems use engraved roller cells or structured surface rolls to pick up precise quantities of coating compound from a reservoir and transfer them to the substrate surface, providing highly accurate thin coating application at low coat weights for functional finishes, adhesives, release coatings, and specialty treatments where precise coating weight control and surface pattern application are the primary requirements.
Role
Provides the precision thin coating application capability for functional textile treatments, adhesive application, and release coating production at coat weights from 1 to 30 grams per square metre where knife coating cannot achieve adequate uniformity, with gravure and rotary systems being the preferred coating method for pressure-sensitive adhesive tapes, release liners, surface energy modification treatments, and printed functional coatings requiring defined pattern application.
