By means of HCU is possible to provide for some specific polyurethane glues, a warm-up conditioning with the purpose to keep constant viscosity and grand excellent constancy application.
Process advantages are the following:
- constancy of glue viscosity
- no necessity to replace adhesive during season temperature change
- Reduce foaming effect
- The warming of the glue is kept heating dosing rollers (ideally with steel dosing rollers).
- HCU heating unit is electrically fed and is complete with temperature control, circulation pump and inox expansion tank and can be interfaced with the main control of the rollers coater.
- HCU is available in different “sizes” to accommodate specific task.
