ApplicationsDry Adhesive on Laminate

Application: 

A manufacturer of home entertainment speaker cabinets drying a water-based adhesive used to laminate vinyl veneer to particle board.

Problem: 
  • Environmental Issues - Due to strict air quality regulations the manufacturer was forced to switch from a solvent-based to a water-based adhesive.
  • Varying Product Widths - The vinyl veneer was laminated to particle board of varying widths.
  • Slow Drying Time - The water-based adhesive had a much greater drying time than the solvent-based adhesive.
  • Limited Production Output - Production output was significantly lowered due to the long drying time of the water-based adhesive.
Solution: 
  • Heat - Two Model 4554-A-38-12 High Density Pyropanels were mounted side-by-side, parallel to product flow, to heat the water-based adhesive on the particle board before the vinyl veneer was applied.
  • Power Control - Two Model 664K Phase Angle SCR Power Controllers controlled the High Density Pyropanels.
  • Heat Zoning - The High Density Pyropanels were configured with center and end heating zones running parallel to product flow.
Benefits: 
  • Faster Drying Time - By applying heat to the water-based adhesive with the Model 4554 High Density Pyropanels, the manufacturer was able to dry the new adhesive as quickly as the solvent-based adhesive had dried.
  • Increased Production Output - Applying heat to the water-based adhesive enabled the manufacturer to match production levels previously achieved with the solvent-based adhesive.
  • Varying Heated Widths - By turning center and end heating zones on and off as appropriate, the manufacturer was able to apply heat to accommodate the varying product widths.
  • Limited Power Consumption - The configured heat zones on the High Density Pyropanels allowed the manufacturer to change the heated width to accommodate varying product widths, keeping power consumption to the minimum level required.
  • Better Environment - By successfully using a water-based adhesive, the manufacturer was able to comply with environmental regulations while maintaining production output.
