Edgebanding Adhesives
Tight glue line at line speed — PVC, veneer, solid wood, melamine, primed HPL. Unfilled EVA and APAO hot melts, and 8600 PUR hot melt. Tell us the edge and the feed rate.
Edgebanding hot melts for furniture and wood-based panels. Unfilled EVA grades for high heat resistance and a wide processing window. Bonds PVC, veneer, solid wood, melamine, primed HPL, and thick solid-wood edges. Custom grades for fast set or longer open time. For heat and moisture resistance after cure, use 8600 PUR hot melt.

PUR hot melt for edgebanding: 8600
Our PUR hot melt for edgebanding is 8600. It is the fast tack grade in our stock PUR table. PUR is a reactive, moisture-curing hot melt. It gives green strength in minutes. Then it cross-links with moisture to a thermoset. After cure, the glue line does not remelt, and it resists heat and moisture better than EVA.
- 8600 — fast tack PUR hot melt; ~4000 cps at 250°F; ~4 min open; also listed for cabinets, steel, woods, and EPS
Full cure is typically 1 to 7 days to full cure depending on moisture, temperature and glue line, with handling strength much sooner; 8600 is typically about 24 hours to full cure. Full specs are in the stock PUR table.
8600 is supplied in 2 kg slugs, 40 lb pails, 260 g standard cartridges (about 63 mm diameter, for common edgebanding machines) and 425 lb drums.
Contains reactive isocyanate. Read the SDS before use; use ventilation and protective gear; hot melt can cause burns. Call us for data sheets
Purge and clean-up
PUR cures with moisture. It will cure in the tank, hoses and nozzle if you leave it. Cured PUR can only be removed by scraping, so purge before it cures. Keep the tank lid closed against humidity.
- Drop pump pressure to zero. Drain the remaining PUR at temperature, using non-metal tools only. Hot material. Wear heat-resistant gloves and eye protection. See the SDS. Call us for data sheets.
- Load PUR-Purge-8530. 9006 PUR purge flake is the alternative.
- Circulate about 15 to 30 minutes at processing temperature. 8600 runs at 235 to 275°F, and PUR-Purge-8530 runs at 250 to 350°F. Allow longer if gel or char is present. Follow the purge product's instructions.
- Push purge through the hoses and nozzle until it comes out, not just the tank. Then flush with a small charge of fresh 8600 until no purge shows, and discard the first few shots. Change any inline filters.
- Start production.
PUR-Purge-8530 is blue so you can see when it's fully displaced the adhesive.
- Cleaning before a run: purge, flush with fresh 8600, then start production.
- End-of-shift or weekend shutdown: purge and leave the purge in the unit. Flush with fresh 8600 at startup. Never run production on purge.

PUR vs EVA for edgebanding
| Point | EVA | PUR (8600) |
|---|---|---|
| Chemistry | Non-reactive. Sets as it cools. | Reactive. Sets as it cools, then moisture-cures. |
| Remelt | Remeltable. | Not remeltable after cure. |
| Heat and moisture | Unfilled grades for high heat resistance. | Better heat and moisture resistance than EVA after cure. |
| Melt system | Simpler to run. | Needs a sealed or moisture-protected melt system. Purge or clean up before it cures in the tank. |
| Cost | Lower cost. | Costs more than EVA. |
| Stock grades | See the stock grades above. | 8600 |
- Choose PUR (8600) when the edge must resist heat and moisture after cure, and your bander has a sealed or moisture-protected melt system.
- Choose EVA when a remeltable glue line is enough and you want a simpler, lower-cost line.
- Choose APAO (7-470) for high heat resistance on HPL and solid woods without priming.
