THE WONDER OF WATER-LESS, SOLVENT-LESS APPLICATION A hot melt coating machine, or slot die coating machine, achieves the application of an adhesive, film, or coating without the use of water or solvents. As mentioned above, in alternative methods, the addition of water or solvents is used to reduce consistency and viscosity of adhesives and coatings in order to allow them to be applied evenly and effectively. However, many adhesives can also be thinned by heating them to the point that their consistency and viscosity are temporarily compromised. The greatest benefit of hot melt or slot die coating over water-based or solution-based applications is the lack of need for a drying element. In a hot melt coater, the adhesive simply firms and regains its viscosity as it cools. This negates the need for extraction of excess liquid or condensation, eliminating the need to deal with exhaust or liquid by-products. The reduced number of steps, along with the reduced periods of interaction with and pressure against substrates results in a decrease in disastrous wrinkling and curling. LESS WASTE, MORE EFFICIENCY Hot melt or slot die coating machines offer improvement to nearly every aspect of the industrial adhesive or coating application process. These machines take up less space and produce far less waste. Their operational costs are lower and allow less opportunity for complication or error. Finally, they virtually eliminate the production of unwanted by products.
