Which edgebanding adhesive should I use?
Choose EVA when a remeltable glue line is enough and you want a simpler, lower-cost line. Choose APAO (Cattie 7-470) for high heat resistance on HPL and solid woods Call 800-249-0337 to confirm whether your substrate needs a primer with 7-470. Choose PUR (Cattie 8600) when the edge must resist heat and moisture after cure, such as kitchens, baths and labs, and your bander has a sealed or moisture-protected melt system.
All three are hot melts and all three run on edgebanders. They differ in how they set, what they resist afterward, and what they ask of your melt system.
EVA vs APAO vs PUR at a glance
| EVA | APAO | PUR | |
|---|---|---|---|
| How it sets | Sets as it cools | Sets as it cools | Sets as it cools, then moisture-cures |
| Remelt after bonding | Yes | Yes | No, after cure |
| Heat and moisture in service | Unfilled grades for high heat resistance | High heat resistance (7-470) | Better heat and moisture resistance than EVA after cure |
| Melt system | Simplest; open pot | Standard hot melt equipment | Sealed or moisture-protected melt system; purge before it cures |
| Cost | Typically lowest | Ask us (call 800-249-0337) | Typically costs more than EVA |
| Typical fit | General furniture, office, contour banding | HPL and solid wood | Kitchen, bath, lab, high-humidity or high-heat end use |
Typical behavior, not specifications. Test on your edge, panel and bander.
Match the grade to the edge and the line
| Edge or need | Stock grades |
|---|---|
| PVC, veneer, solid wood, melamine, primed HPL; tight glue line | 7-495C unfilled fast-setting EVA |
| Light-colored edges where the glue line shows | 7-496C opaque unfilled EVA |
| Primed PVC, veneer, HPL, melamine paper, thick solid wood | 7-497 / 7-498 unfilled fast-setting EVA |
| High-speed, economical; resists pot discoloration | 7-430 fast-setting EVA |
| Contour banding; longer set at lower temperature | 7-406 unfilled low-viscosity EVA |
| Medium set; cartridge option | 7-480 / 7-480C, 7-482 / 7-482C |
| HPL and solid woods; high heat | 7-470 APAO |
| Heat and moisture resistance after cure | 8600 PUR: ~4000 cps at 250°F, ~4 min open, runs at 235 to 275°F. 8600 typically takes about 24 hours to full cure. PUR in general typically gives handling strength in minutes and builds much of its strength in the first day; full cure typically takes 1 to 7 days, depending on moisture, temperature and glue line |
8600 comes in 2 kg slugs, 40 lb pails, 260 g standard cartridges (about 63 mm diameter, for common edgebanding machines) and 425 lb drums. Full stock grade list: edgebanding adhesives.
Contains reactive isocyanate. Read the SDS before use; use ventilation and protective gear; hot melt can cause burns. Call us for data sheets
Slow vs fast lines
Faster feed rates need faster set; slower or manual and contour work needs more open time. Cattie can formulate custom grades for fast set or longer open time. Tell us the feed rate.
What to send us
Edge material and thickness, panel type, bander make and melt unit, feed rate, and where the furniture ends up (dry room, kitchen, bath, lab).

Edgebanding adhesive FAQ
Is PUR better than EVA for edgebanding?
For heat and moisture resistance after cure, yes. PUR does not remelt once cured. EVA is simpler to run and lower cost, and is enough for many dry-room furniture jobs.
What is APAO edgebanding hot melt?
APAO is an amorphous polyolefin hot melt. Cattie 7-470 is a high heat-resistant APAO for HPL and solid woods. Call 800-249-0337 to confirm whether your substrate needs a primer with 7-470.
Which Cattie grade is for PUR edgebanding?
8600: fast tack PUR, about 4000 cps at 250°F, about 4 minutes open time, run at 235 to 275°F. 8600 typically takes about 24 hours to full cure. PUR in general typically gives handling strength in minutes and builds much of its strength in the first day; full cure typically takes 1 to 7 days, depending on moisture, temperature and glue line.
Does PUR need special equipment on my bander?
PUR needs a sealed or moisture-protected melt system, and it must be purged before it cures in the tank. Call 800-249-0337 with your bander and melt unit to confirm fit.
How do I get an edgebanding sample?
Call 800-249-0337 or email sales@cattieadhesives.com for an adhesive or a sample. Tell us the edge, the panel, the bander and the feed rate.
