HIPUR WW30 Hot-Melt Glue, Amazing product No-picture-s No-picture-s Click the pictures to enlarge them

This is a great concept. If anyone is wondering whether or not its a necessary expense, i’ll go over a couple of things from my experience so far. I ordered the Hipurformer Glue gun, which came from Franklin, it said Steinel on it when i opened the box. I ordered the WW30 cartridges to start and they came with the glue gun through WoodWorkers Hardware.

The front part of the glue gun is where you put the cartridge, then you attach it to the handle. I plugged it in and waited the 12 minutes it takes to heat up.

First test: 2 pieces of 8/4 Walnut, 20”x5” tapered to 2”x2” with perfectly cut 45’s on the ends. I attached the 45’s end grain to end grain. Here’s what i noticed using the Hipur without a clamp:

The wood should be heated up a little first. The WW30 sets extremely fast and if the wood is on the colder side of say 65 or even 70 its even faster: i pressed them together by hand and there was a gap in one tiny spot. That then turns white. Contrary to what the product claims, unless its very thin wood, you cant heat it up again and disconnect it.

I used too much and although i was pressing it together as hard as i could, its still a slippery surface so you have to work quickly and diligently (thats the point where that tiny gap evolved)- its tricky to quantify how much you’ll need to begin with also.

So, first trial, a tiny bit of white showing on a Walnut joint, very easy to see. The heat gun i have turned it clear again and it stayed that way. Although it was smaller than a hair of a gap and less than a 1/4 long, it was noticeable enough to see what i did wrong so far, by using too much glue and it setting faster than 30 seconds with the cooler temp making it even harder to push together.

The next glue test of the same pieces. This time i heated them up. The joint was still slippery to hold together by hand but there was a longer set time and the joint face to face flat, no gap. The reason why i chose this test was due to the time it takes to clamp and glue something of this nature in a jig/template, on a flat table, not really able to see the underside of that joint.

I wanted to see if it would replace the Domino jointer i normally use for this application.

RESULT:
The strength of the joint is nothing short of absolutely amazing. Without a 50 mm tenon in it. Ive used all the Titebond glues, Epoxy based adhesives, and in the Commercial Construction industry I’ve used even more.

As far as wood to wood adhesion, theres nothing I’ve found outside of this particular urethane based hot melt system, that is anywhere near as strong as this, end grain to end grain.

Benefits once you’ve used it a couple times:

-Less waste. The WW30 per cartridge is expensive. Normally you have to cover all of the joints, mortises with regular glue. When clamped together a lot of that glue gets squeezed out like it should- but- its more waste.

-Superior strength, and fast. 690 Psi instantly, 1,096 in an hour and somewhere around 1396 Psi after 24 hours.

-Youre actually done with the gluing stage in 30 seconds (or 60 with the WW60).

Great for smaller projects. WW60 works exactly the same.

Downside: Again, its really difficult to quantify the amount needed for long pieces for say a table top. The cartridges hold about as much as a regular size tube of toothpaste. The manufacturer explaining it in grams, or ounces doesn’t help, we’re not Chef’s..

- $9 to $12 per, with shipping being around $15 on average. You pay for not having to wait i suppose.
-Wont do well in situations where it would be in the sun, or in hot places.
-Havent seen any tinted glues yet. Make no mistakes, it doesn’t blend well with darker wood it turns white as it hardens.
-Keep an eye on temperature if possible. Nobody really knows how hot or cold the wood you’re working with is. The glue has a set temperature range though.
-Takes a while to heat up.
-Although i havent experienced it yet- I have read a lot of reviews and people complain of paying for and receiving hardened cartridges. The “Franklin format” of manufacturers date/use by date, is not in a recognizable format to the average person.

Overall, an amazing product. It does exactly what it says it does. And is as strong as it says it is, and also works as fast as it claims. Needs a little more work before it totally takes over the glue world.

I have always thought why cant hot glue be as strong as wood glue…. Now it is!

Thanks for the info.

What would you consider “too hot” of an environment for using this glue?

I am building an RV and want seriously strong joints in my work. However, while sitting idle between trips it can get up to 110F inside.

Is that too hot?

Thanks.
