What is Edge Banding Glue? Where is it used? EVA and PUR Selection
Edge banding glue is industrial adhesive used to fix PVC, ABS, melamine, acrylic or wood edge banding to the cut edge of furniture panel. It can be applied as EVA or reactive PUR hot melt in automatic edge banding machines. The right product; The panel and band surface are selected according to line speed, machine type, visible joints and expected heat/humidity resistance.
Edge band glue is an adhesive that protects and aesthetics the cut edge of the furniture piece by creating a permanent bond between the panel and the edge band. Regular transfer of glue to the surface in the edge banding machine, adequate contact with the tape, correct operation of the pressure rollers and removal of the residue by the finishing section determine the final appearance.
What is edge band glue?
These products are generally in hot melt EVA or reactive PUR hot melt form. While EVA provides rapid initial adhesion through physical cooling, PUR can improve final strength through moisture reaction after initial bonding. Neither technology works with the same machine settings; tank and nozzle temperature, application amount, belt tension and machine speed should be adjusted according to the TDS of the selected product.
A good edge band glue; It must provide compatibility with the panel and belt material, balanced wetting, controlled open time, low overflow, adequate initial adhesion and stable flow at line speed. For application, selection guides and current product documentation at Koçak Endüstri technical information center should be evaluated together.
Which edge bands are used?
| Tape or panel | Priority check | Note |
|---|---|---|
| PVC and ABS | Surface energy, tape backside and wetting | Open time and grammage are important at high line speed. |
| Melamine and paper | Absorbency, surface smoothness and pressing | Excess glue may create visible joints and cleaning burden. |
| acrylic and glossy tape | Scratching, cracking and surface tension | Machine, cooling and appropriate process chemistry must be handled together. |
| Wooden and solid tape | Moisture, fiber direction and surface leveling | Material movement and long-term strength should be tested. |
EVA or PUR?
EVA edge banding glue is frequently evaluated for standard indoor furniture, economical production and rapid commissioning. PUR edgebanding glue is used for moisture, heat, steam or long-term resistance critical; It can stand out in applications where thin adhesion line and higher final performance are expected. When using PUR, the product must be protected from moisture, the equipment must be cleaned according to the manufacturer's procedure, and the curing time must be taken into account.
It is not right to recommend a definitive product just by looking at the type of tape without seeing the machine or the surface. Panel coating, tape back surface treatment, line speed, product color, operating temperature, cleaning system and quality target should be evaluated together. For relevant product families, you can review the Jowat product portfolio.
Machine settings and checklist
- Check tank, hose and nozzle temperatures individually.
- Observe glue film continuity on the application roller or nozzle.
- Verify that the panel surface is free of dust, oil and loose fibers.
- Line speed Evaluate with open time and cooling behavior.
- Check belt tension, pressure rollers, alignment of cutting and finishing units.
- Record adhesion, bleed, joint appearance and corner strength on the first part.
How to inspect adhesion problems?
If the tape opens or separates at the corners, first check the surface cleanliness, temperature, glue weight, pressure, line speed and the back surface of the tape. If the glue is threading, temperature, viscosity, nozzle geometry or shear behavior should be examined. If there are many visible joints, the application amount, surface compatibility and pressure setting should be retested. Sample by changing one variable by itself; changing several settings at once hides the root cause.

What is Edge Banding Glue? Where is it used? EVA and PUR Selection hakkında merak edilenler
Is EVA or PUR used for edge banding?
Both can be used. EVA in fast and economical standard production; PUR, on the other hand, is evaluated when humidity, heat and long-term durability expectations increase. Final selection must be verified with panel, tape, machine and production sample.
Why does the edge band open?
Insufficient heat or weight, dirty surface, improper printing, high line speed, tape backing incompatibility and machine misalignment are common causes. TDS values must first be compared with actual machine conditions.
On which materials is edge banding glue used?
It can be used with the appropriate product family on PVC, ABS, melamine, acrylic, paper, wood and solid edge banding. Compatibility should be tested based on the tape's back surface treatment and panel finish.
