Degraded adhesive build-up, “char” is a common issue in all hot melt systems. This can be caused by several factors, including material incompatibility, application conditions, and frequency of system maintenance. The good news is that there are several things you can do to prevent or mitigate adhesive build-up before it causes problems with your system.
1. Use The Right Adhesive Product For Your Application.
Make sure the hot melt adhesive you’re using is compatible with the substrates you’re bonding and the conditions under which the bond will be subjected (temperature, moisture, etc.). If you’re not sure which adhesive product to use. This will be mentioned on any of the Glues packaging.
2. Apply The Adhesive At The Correct Temperature.
Applying adhesive at too high or too low a temperature can cause it to thicken or thin and not perform as expected. Follow the manufacturer’s recommendations for application temperature to ensure optimal performance.
3. Use An Appropriate Size And Type Of Nozzle.
The size and type of nozzle you use can impact the flow rate and pattern of the adhesive, which can in turn affect how well the adhesive bonds to the substrate. Choose a nozzle that will provide an even coverage.
4. Keep Your System Clean.
Adhesives can harden and clog up hoses, modules, and other parts of the hot melt system if they’re not cleaned out on a regular basis. Perform regular maintenance according to the manufacturer’s recommendations to keep your system running smoothly and prevent adhesive build-up.
