Adhesive for Honeycomb Panels — Aluminum & Paper Honeycomb
Polyurethane honeycomb panel adhesive engineered to laminate aluminum honeycomb and paper (kraft) honeycomb cores to aluminum, GFRP, stone, HPL and plywood skins — a lightweight, high-strength, gap-free structural bond with cure time tunable from 15 min to 8 hours.
One adhesive for aluminum & paper honeycomb panels
PUGLUE polyurethane honeycomb board adhesive bonds aluminum honeycomb and paper / kraft honeycomb cores to a wide range of facings with a lightweight yet high-strength bond. It resists corrosion and ageing in harsh environments, cures from a tunable 15 min to 8 hours, and works across construction, transportation, marine and aerospace panels. Solvent-light and built for repeatable, high-volume lamination.
Aluminum Honeycomb vs Paper Honeycomb
“Honeycomb panel” covers two main core families. Both are bonded with PUGLUE polyurethane adhesive — the right grade depends on the core, the skin and the end use.
Bonds Every Honeycomb Core & Skin
One polyurethane system covers the full range of honeycomb cores and facing materials — including mixed metal-to-board builds.
Honeycomb cores

- Aramid (Nomex) honeycomb
- PP / thermoplastic honeycomb
Facings / skins
- Aluminum & steel sheet

- HPL, laminate & melamine
- Stone, marble & plywood / MDF
Mixed builds
- Metal-to-honeycomb bonding

Types of Honeycomb Panel Adhesive — and Which to Choose
Honeycomb panels are bonded with several adhesive chemistries. PUGLUE supplies polyurethane systems matched to your core, skin and production method.
| Adhesive type | Form | Best for | Notes |
|---|---|---|---|
| Two-component PU (2K) | A + B | Production lamination, structural aluminum honeycomb | Chemical cure — consistent, fast, high shear. PUGLUE core product. |
| Single-component PU (1K) | 1K moisture-cure | Paper honeycomb, doors, lower volume | Simple to apply; cure depends on ambient humidity. |
| Epoxy film / paste | Film or 2K paste | Aerospace-grade aluminum / Nomex honeycomb | Very high strength; needs heat-press / autoclave and longer cure. |
| Modified epoxy / acrylic | 2K | Demanding metal-to-metal honeycomb | High peel strength; higher cost, more sensitive mixing. |

Curing time & how to press
PUGLUE honeycomb adhesive cure time is adjustable from 15 min to 8 hours to suit your line. The panel must enter the press within 1/4 of the set cure time — e.g. for a 1-hour cure, glue-to-press must happen within 15 min, or bond strength suffers. With a heated press, run 80°C ± 20°C for ~15 min. Maintain even pressure across the full panel for a flat, gap-free bond. Read why honeycomb glue sometimes fails to bond before you scale up.

Frequently Asked Questions
Honeycomb panel adhesive — technical answers for aluminum and paper honeycomb manufacturers.
What is the best glue for aluminum honeycomb panels?
A two-component polyurethane (or, for aerospace grade, epoxy film) adhesive gives the high shear strength and ageing resistance aluminum honeycomb needs. PUGLUE 2K PU laminates aluminum honeycomb cores to aluminum, stone and GFRP skins with a gap-free structural bond. More detail: best glue for aluminum honeycomb panels.
Does the same adhesive work for paper (kraft) honeycomb?
Yes. Paper / kraft honeycomb used in doors, furniture and packaging bonds well with PUGLUE polyurethane adhesive, which spreads evenly and cures fast for flat, lightweight panels. The grade and open time are tuned to the porous paper core and your skin material.
Which cores and skins does it bond?
Aluminum, paper / kraft, aramid (Nomex) and PP honeycomb cores — laminated to aluminum, steel, GFRP / CFRP, HPL, stone and plywood / MDF skins, including mixed metal-to-board builds. See how to choose an adhesive for composite honeycomb panels.
How long does honeycomb adhesive take to cure?
Cure time is adjustable from 15 min to 8 hours per your requirement. The panel must enter the press within 1/4 of the set cure time; with a heated press, run 80°C ± 20°C for about 15 min.
Why is my honeycomb glue not bonding well?
Common causes are too little adhesive, uneven pressure, exceeding the open / press window, or a contaminated skin. See our guide on why honeycomb glue fails to bond for a full checklist.
Is honeycomb adhesive resistant to chemicals and moisture?
Cured PUGLUE polyurethane is resistant to moisture and many chemicals, which is why it suits marine, transport and facade panels. Details: chemical and moisture resistance.
What are the aerospace standards for honeycomb adhesives?
Aerospace aluminum and Nomex honeycomb bonding is governed by standards covering peel, shear and environmental ageing. See aerospace standards for honeycomb adhesives.
Are there low-VOC / environmentally friendly honeycomb glues?
Yes — lower-VOC polyurethane and bio-based options are available for green-build and indoor applications. See low-VOC honeycomb glues.
Can I re-bond a honeycomb panel that has fallen off?
In many cases yes, after cleaning the bond line back to sound material. See re-bonding a fallen honeycomb panel.
Do you offer samples, TDS, MOQ and OEM supply?
Yes. We provide a full TDS, free samples for line trials, and OEM / private-label supply with manufacturer-friendly MOQs. Contact us for a quote matched to your honeycomb panel type and line speed.
