PUR Hot Melt Adhesive
Edge banding adhesive is a type of glue used in furniture manufacturing and woodworking to bond edge banding materials (such as PVC, ABS, wood veneer, or melamine) to the edges of panels (such as particleboard, MDF, or plywood). It enhances the appearance, durability, and moisture resistance of the finished product.
Product Details
PUR is a one-component, moisture-curing reactive adhesive. After initial hot-melt application, it continues to cross-link with ambient moisture over 24 hours, forming a permanent 3D molecular structure. The result: a thinner, near-invisible glue line, stronger heat/water resistance, and a bond that will not re-soften — making it the standard choice wherever furniture will face steam, heat, or repeated cleaning.
Our 803 series includes different viscosities, open times and processing temperature ranges to match different edge banding machines, production speeds and workshop conditions.
Jiwei supplies PUR adhesive for sample testing, regular furniture production and bulk industrial use, with TDS/MSDS and technical selection support available.
If your application involves flat surface bonding rather than edges, see our PUR for Flat Lamination or PUR for Profile Wrapping pages for the right formulation.

For 803.70/803.71, glue consumption varies depending on panel structure and surface condition.
| Panel Material | Recommended Glue Spread |
|---|---|
| MDF / Density Board | Approx. 90–120 g/m² |
| Plywood / Multi-layer Board | Approx. 100–130 g/m² |
| Particleboard | Approx. 120–150 g/m² |
The final glue amount should be adjusted according to:
● Surface roughness
● Panel density
● Edge material
● Production speed
● Required bond strength
● Machine condition
Using too much adhesive can increase consumption and create a visible glue line, while insufficient adhesive may reduce bonding reliability.
| Item | PUR Edge Banding Adhesive | EVA Edge Banding Adhesive |
|---|---|---|
| Bonding Mechanism | Moisture-reactive curing | Thermoplastic cooling |
| Heat Resistance | Higher | Standard |
| Moisture Resistance | Higher | Standard |
| Glue Line | Thin and clean | Conventional |
| Final Bond | Cross-linked bond after curing | Thermoplastic bond |
| Typical Application | Premium furniture, kitchen and bathroom furniture | General furniture production |
| Equipment Cleaning | More attention required | Easier |
PUR is generally preferred when the manufacturer requires better resistance to moisture, heat and long-term environmental exposure.
EVA remains suitable for general furniture production where processing simplicity and cost control are the main priorities.
PUR adhesive develops initial bonding strength after application and cooling, then continues to react with moisture in the air.
For 803, under suitable temperature and humidity conditions, most moisture curing develops gradually over approximately 3–7 days.
Curing speed is affected by:
● Workshop temperature
● Relative humidity
● Panel material
● Edge material
● Adhesive amount
● Production conditions
Customers should allow sufficient curing time before carrying out demanding performance tests.
Beyond edge banding, Jiwei's PUR platform covers the full furniture production chain — from Honeycomb Board bonding to Textile lamination and Liquid PUR Adhesive for structural bonding.
All formulations are backed by ISO9001, ISO14001, ISO45001 and IATF16949 certification — view our full certificate library— and produced at our 15,000+ ton annual capacity facility, detailed on our R&D & Quality Control.
Whether you need a single trial batch or full-container OEM supply, request a custom PUR edge banding quote and our engineers will match the right viscosity and open-time formulation to your line speed.
Confirm the materials to be bonded and the edge banding strip (including the bonding panels, edge banding material, machine edge banding speed, adhesive melting temperature, and final strength)
Clean the gluing equipment, activate the temperature control panel, and heat the adhesive.
Access the equipment control panel to set parameters including edge banding speed, adhesive application volume, and trimming settings.
After completing the panel edge banding, inspect the results. If satisfactory, allow the bonded panels to rest for 24 hours before proceeding to subsequent processes.
PUR edge banding adhesive should be stored in its original sealed packaging in a cool and dry environment.
For selected 803 grades:
● Recommended storage temperature: below 40°C
● Keep away from direct sunlight
● Avoid moisture exposure
● Use opened packaging as soon as possible
● Shelf life can be up to approximately 6 months depending on grade and packaging
Always refer to the latest TDS for the exact storage period of the selected product.

PUR Edge Banding Hot Melt Adhesive FAQ
Q1. Why does the edge banding strip detach from the board immediately after the edge banding process?
A1.. The edge banding tape is too thick and incompatible with the selected adhesive. b. Insufficient adhesive application. c. The selected adhesive has an excessively long development time. d. Edge banding speed is too fast, resulting in poor initial tack strength of the adhesive. e. Melting temperature setting is too low. f. Insufficient pressure from the pressure roller.
Q2. Why does the edge banding detach from the panel during subsequent processing?
A2. Insufficient dwell time in ambient conditions. b. Inadequate adhesive application. c. Low ambient temperature or humidity preventing adhesive curing. d. Incompatibility between the selected adhesive and the substrate material.
Q3. When replacing the adhesive suction cup with a new bucket, is cleaning required?
A3. No cleaning is needed for consecutive use. However, for first-time use, thoroughly clean both the suction cup and suction tube before application.
Q4. Can PUR edge banding hot melt adhesive be used year-round?
A4. Yes, Blue Rhino universal PUR hot melt adhesive can be used between 10-35°C (excluding extreme weather conditions). However, we recommend using fast-curing types in summer and slow-curing types in winter.
