Anyone using Weld-On glue here?

Weld-On #3 is now sold as Sci-Grip #3.  Same stuff, different name.  There are two types of 'weld-on'....#3 and #4.  #3 is 'hotter' than #4 and, therefore, sets quicker. It is, however, not as quick-setting as Tenax.  The active ingredient is methylene chloride, which means it's a hazardous material.  BE SURE to read the MSDS on this stuff!!  Use it with PLENTY of ventilation!!!

Good luck!

I was intorduced to Weld On 3 back in the early 80s and was hooked on this type of liquid cement. I have not seen it for several years and now use Pro Weld, which is practically identical.  I also use Tenex but its kind of harsh on some plastics.

Several years ago, I was looking for a cheaper liquid plastic glue and came across Methylene Chloride at a plastics supplier. For all practical purposes, it is the same as Weld On #3 but much cheaper (at that time Weld On #3 was something like $3.95 for 2 ounces, while Methylene Chloride was 5 bucks for a Quart. The last gallon I bought cost me about 25 dollars and will last 3 to 4 years. I have a couple of empty Weld On jars that I fill and keep on my modeling desk (the rest goes into an old fridge that I store volatile liquids in. Check your local phone directory for a plastics distributor and give them a call.

I have never used weld on, I do use Tenax and Tamiya quite a bit.  On occasion I will use plasti strut or the flexi file brands.  I like that style of glue and I try to keep a few different brands around as they work better depending on the plastic.

 

on a side not, I love TAP plastic, I hit the store up every chance I get

I've never used Weld-On, nor even seen it (I followed your link, to take a look).

For liquid styrene cement, I use Plastruct's Weldene and Bondene, they work pretty well for me.

Hi;

    I used to till I discovered the Tamiya line of glues .Now I use them exclusively .I still use Testors , but haven't seen Weld-On #3 for quite a while .  T.B.

I used to used weld-on all the time but haven't seen it in years.  Either our shop here doesn't carry it anymore, or I just keep missing the shipments.

I take it weld on is a brand name . Is it the type of glue that melts the two halves together

I use Plast I Weld and Tenax and get excelent results. The bottles last me a very long time and i use them for about 90% of my gluing and applied with a Touch N Flow applicator.
