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.
