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.
