Weld-On 40

[big t]

Hey Guys

Does anyone here know anything about using Weld-on 40? I am planning on using some soon, but have never used it. My specific questions are how to accurately measure out the two parts, get them mixed and what it a good tool to apply it? I think I have heard of peeps using a big 30cc syrenge. Any thoughts on where to get one of them?

Thanks

Tom thier are a couple ways to do it. One is to use a gun that automatically mixes it. another is to mix it by hand in a container and then put it in a injection syrenge and apply, you will only have a certain ammount of potlife on it though

Hey Tom,
I know a little about weld on 40 What are you trying to do? That will help in figuring the best way to apply. It dosn't matter if you use the gun or self mix the working time is the same.

Hey John, I am glueing a new overflow in a old tank that has a potbelly back. It is a 90 made from 3/8's. So anyway it took some major shaping to make the overflow match the back of the tank. As much as I tried I could not get the gap to be absolutely perfect along the entire curve. Mind you it is only about 1/16'th at the most, but I think that weldon-40 would be the best application. So there you are. So do you think that the weldon-40 is my best bet? and shoud I use a big syrenge? I was going to grind in a bit of a angle for the glue to go into to give it plenty of room to 'bite'

Thanks

Stircrazy,

Weldon-40 is a much thicker 2 part mix that is thicker then 16, but it does not go bubbly. Also it does not weld w/ solvent action but more cement action as far as I have read.

Tom,
yea that sounds like a perfect application for 40, the syringes we use are more comparable to those ones you put a babies medicine in to get it in thier mouths. No needles or nothing. The gun is quite expensive and does the same job as hand mixing it, it's just that the gun comes on quite handy when your using alot of it and if you hand mixed it, it would start to cure before you could get it all applied. Hope that clears it up.

Stircrazy,
Think of weld on 40 as basically liquid acrylic that dries hard, whereas 4 is a watery solvent that basically melts two pieces of acrylic together

Weld on 40will be the best way to make that seam. Mix it 10 to 1. I had a hard time at first getting the mixture down but that seems to work best. If you need a syringe I could send one to you we have a couple of bags of them. You should be able to fill that void with the 40.

Wow John, that is a nice offer! Thanks. I think that I can probably find a syrenge around here somewhere in a medical place. Thanks tho I appreciate it. I will go with 10 to 1 and give it a shot.

thanks for you help
