Always ensure that you are using the correct equipment for your hot melt formulation and that you are using the correct instructions for your formulation. Very often, problems with hot melt adhesion are due to the temperature of the glue – either too hot or too cold will affect the strength of the bond. Equally, you must ensure that the bonding surfaces are clean and free of dust, oil, and grease, and that the correct amount of adhesive is being applied.
