EVA glue for edge banders

1/9/25       
Armando Member


I wonder what type or brand other people using for their edge banders
I have a SCM K230 edge bander is a slow speed machine 9-m/min
50k-70k mpas / Viscosity at 185 degree / Year 2015
Glue pot 180 -200
I tried PO glue but my machine is slow speed and up to 200 degrees it did not work on my edge bander
I am having problems with the edge banding adhering properly to my materials and only have this problem during winter time. The building gets too cold because it’s all metal building without insulation.
I have used Jowat 280.30 and tried other glues and edge banding brands and still having problems in winter time.
My shop gets about 20 degrees cold and most of the glues is good for 50 degrees cold room temperature.
The day that I put the edge banding it holds good but in few days the edge banding peel right off.
I need to find a glue that will hold for a lower temperature room
I appreciate any advice.

Thanks…Armando

Does your edgebander have a panel heating device that is ahead of the glue pot? It's specifically made for your condition. I think they are turned off by default. This makes a big difference for us in the winter.

How big is your shop?

Bozzy,
Shop is 5000 sq ft
My edge bander does not have a heat panel device, I think the problem is the
shop that it's too cold because the same day that we run the edge bander we have no problem with the edge banding adhering to the materials.
The problem is after a few days the cabinets sit in the shop all day and night and that is when the edge banding, if you pull on it comes right off.
I am looking for a glue that will hold in a low room temperature
20 degrees F. o lower degrees.

Not sure what your volume is, but it seems like you need to start heating your shop. We spend about $1000/month to bring the shop temp to 50-55 when outside temp sits around 32.

Yes,
Looks like I need to do something to heat up the shop.

A nice diesel torpedo style heater will go a long way to helping you here.

Also make sure your edgeband isn't old. We throw away stuff that's over a year old. The primer on the back of edgeband goes bad, especially quickly in humid places like where I live. The $50 you save on a job isn't worth having a kitchen to redo.

Your edge banding issues are likely due to your shop's low temperatures (20°F in winter), which are far below most adhesives' minimum operating temperatures. To address this, consider heating your workspace with portable heaters or insulating the building for long-term improvement. Switch to a low-temperature hot melt adhesive, such as a PUR glue like Jowatherm-Reaktant 607.40, which cures better in cold conditions, and ensure materials are preheated to improve adhesion. Adjust your glue pot temperature (if possible) and machine pressure settings to optimize bonding. Alternatively, consult adhesive suppliers like Jowat or Kleiberit for winter-specific glues and test flexible edge banding materials like Rehau. Warmer conditions and the right adhesive should resolve your issue.

I keep my shop at 60 in the day but when I run the bander before it heats up I use this heater to warm the edgebanding I make a small ten

The edgeband primer tip is something people overlook constantly — old stock sitting in a cold damp shop is a silent killer for adhesion. But at 20 degrees the real fix has to be the shop temperature. A torpedo heater gets you through the season without a massive investment, and prewarming your panels and edgeband before a run makes a noticeable difference even before anything else changes.

Armando,

From the edge banding and adhesive side, I would treat this as a temperature/wetting problem first, not only a glue-brand problem. At 20°F the panel core, PVC tape, and glue line are all pulling heat out of the hot melt very fast. The edge can feel bonded on the day of production, but if the adhesive did not properly wet the back primer and board edge, the peel failure shows up after the parts sit in the cold shop.

A few practical tests:

1. Store the PVC tape and panels in a warmer area for a day before running, then run a small batch and peel test after 24-48 hours.
2. Check the age and storage of the PVC edge banding. The primer on the back of the tape matters a lot; old or damp stock can fail even with a good EVA.
3. Do not only raise the glue pot temperature. On a slow machine, too much heat can shorten open time and make stringing or poor transfer worse.
4. If the SCM has a panel preheater or edge warming option, use it. If not, prewarming the tape roll and panel edge is still worth testing.
5. PUR can help in some cases, but it is not magic at 20°F and it brings cleanup/storage issues. A low-temperature EVA or suitable PO may be easier if the machine speed and temperature range match.

For testing, mark tape age, glue, pot temp, shop temp, and panel/tape preheat condition on short samples, then peel them the next day and again after a few days. That will tell you whether the issue is glue, PVC primer, or cold material temperature.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
