Weldon #4 Applicator Bottle - 1/4 Pint (4oz) - 10308 - Single Unit

DeeCee: I bought this for gluing my acrylic display unit. I thought it was a good idea to have the applicator, but turned out the applicator was a piece of junk. It leaked crazily, so I just scraped it and used a syringe instead. The glue itself is pretty good, and bonds fast but it may take about 24 hours to fully cure.

NOIGUY: Worked well ar repairing boat windshield. As pointed out in other reviews, very watery, hard to apply on vertical surface.

Mr. Mod: You barely need any of the liquid to fuse two pieces of plastic together.

It works great creating leakproof strong bonds between two pieces of acrylic.

I used about half of a 4oz bottle to seal 2 HUGE snake enclosures.

Randall L. Johnson: For the appropriate types of plastics and joints, this glue is great. It is "wicking" consistency, i.e., runny as water without the surface tension. It will wick into a tight joint and 'melt' the parts together. The applicator bottle is marginal for use with this solvent. First, it does NOT seal tightly enough. The solvent will evaporate in just a couple of hours with the lid on tight and the needle cover in place. Second, the needle is too big for this very thin solvent. The solvent will run out the needle just by pointing it down ; no squeezing needed. Which makes it difficult to control application of the solvent. Apply to the back side of the piece being glued to avoid an unsightly mess.

Henry G. Silvia: I came back to order some more because I am running low, but it 100% does the job as advertised. Let's address the complaints:

1) Impossible to open! Well, yeah, if it opened an easier it couldn't be shipped and wouldn't be safe. Ask yourself this: If you can't outsmart the container, should you really be using the contents? (answer: no)
I went through the same frustration when I got mine, and instructions could be better, but it is intended for industrial use (pros), not us crafters, so take it for what it's worth.

2) It's no different from rubbing alcohol ("I spilled it on my hands and nothing happened!) - Uh, no. It's meant to WELD acrylics. It is NOT (any sort of) glue. It literally melts plastics and welds them together, it does not ADD a glue/cement to adhere 2 substrates. If you have NOT researched the chemical bond process then please, do not buy this. YOU have a responsibility to understand the product before you buy and attempt to use it.

3) It started to harden in the can! This is a lie. There is nothing to harden. Worst case it would evaporate (it will do so VERY quickly, so don't leave it open).

4) The included squeeze bottle is... yeah,...

FlintersFlinters: Super thin viscosity, thinner than Tamiya Extra Thin Cement. This works on thermoplastic materials. I tested it out on styrene and it is crazy strong and fast. I also tested it out on PLA for 3D printing it it works on there too. It is *not* gap filling, so have a good fit first.

The bottle, much has been said how badly it leaks, and with good reason. There is no seal at the joint between top of bottle neck and the cap. It easily leaks along the screw threads, but there us an EASY solution.

5/8" OD rubber O Ring. Put one of these in the cap and now it seals 100%. Done.

The steel needle tip can clog if you drag it along a seam for styrene or PLA. I had to clip the tip off as I had no wire that small to clear it. Now that I am aware of this I can avoid it.

Bulk cementing sheets of styrene together works fantastic.

Bamazon: My fridge crisper trays had pieces broken and cracks and I was about to throw them out with the assumption I’d just buy new ones.
But new ones are stupidly expensive and can be 1/3 the price of the actual fridge. It’s such a huge rip off so don’t go waste your money.
I bought this and followed along with a youtuber who also did not want to be ripped off and buy new trays.
Anyway this worked like a charm. It slips into the cracks easily and I used masking tape so it wouldn’t drip through to the other side of the crack. Also use gloves, goggles, mask and cover/protect your work surface and do it in a ventilated area.
TIPS:
When I bought it the lid would not open so I emailed the company and they said this is normal and to use a wrench to open it. Then there is second lid you have to open (this stuff evaporates easily hence the double lid and tight seal). I recommend NOT taking this second lid off and instead using a screw driver to pierce a hole into (with a hammer but be gentle) and then using a long neck pipette to transfer into the squeeze bottle it comes with. That way in a few months it won’t have all evaporated. You don’t need very much of this stuff...

Michael Vanchu: I bought this to assemble an acrylic display case. I do not understand how the chemistry behind this product works but it is amazing. It doesn’t bond to anything else. It is applied to the seams and bonds the acrylic to itself but the excess merely evaporates and doesn’t leave any marks. Truly amazing.
