Hot Melt Coating is the application of a layer to a substrate by pre-melting the desired material and then allowing or forcing the material to cool, solidifying the layer. The process is widely used in industry, including pressure-sensitive adhesives, labels, pharmaceuticals etc. The process has been used so extensively for the application of adhesive layers by slot-die coating that the use of the term ‘hot melt’ often implies slot-die coating, but hot melt methods have also been used for other coating processes, such as metering rod or roller coating.
