Adhesive Char = Higher Downtime, Rejects, and Operational Costs...Get more productivity and lower your total cost of operation!!
Adhesive char is present in your hot melt hose....even if the adhesive in your tank is clear. Time & Temp & O2 = Adhesive Char
- Every hot melt adhesive has a pot life - a point in time at which the heat and oxygen cause it to degrade.
- Heating elements in hot melt hoses are used to keep adhesive flowing at the right viscosity and temperature.
- Char forms during idle periods when your system is on/heated and no adhesive is flowing.
- Adhesive near the heated walls of the hose moves slower than the adhesive in the center of the hose. This hotter, slower adhesive degrades faster and sticks to the hose wall - forming char.
- Char inside the hose breaks loose and clogs filters, guns and nozzles.
- Lower-grade hot melt adhesives degrade and form char more quickly.
