Conversion resin
« on: September 24, 2008, 03:18:59 AM »
Does anyone know of a resin or epoxy that is runny enough to penetrate though a gap of 1/16" ? I have my neos super glued on to the magnet cage (pvc) and the rotor. I have about a 1/16" gap bettween my cage and the rotor and would like to fill it with either a resin or an epoxy. I need something thin enough so it will flow around the round neos also, they have about 1/8" gaps bettween them. I can turn it up on end and make kind of a form/funnel to get it in. Thanks for the help!

MAS, System3 or WEST resin should be thin enough to penetrate 1/16th inch holes.


If a slow-setting epoxy is used the air will have time to escape before the epoxy sets.

You can thin epoxy with alcohol. It worked well for me with no side-effects.

will the space that the epoxy takes up shrink?

I don't advise using any solvent thinning on epoxy BONDING work. It is a good way to create a failure.


As you guessed 2windy... it WILL shrink. Sometimes the solvent will 'flash-off' before the epoxy cures ... I have had it not flash completely off and take a long time - weeks  - to finally cure ... and it did SHRINK.

I didn't have any shrinkage. Given that I was laminating a boat I'm not sure I would have seen the effects like you'd have with cast objects, but I'd assume I'd have it peeling off of previous layers if it had. I did not notice any significant change to the curing time.


This was the generic 2:1 epoxy from US Composites (shopmaninc.com).

A gentleman on the backshed.com forums used West Systems epoxy (105/205) for waterproofing and insulation on his huge conversion project...

if you heat the resin and hardener separate to a little over 100f. it will thin out a lot .

you set up time will shorten quiet a bit. so if you can work fast before it goes thermal then it should wok for you well.
