Australian equiv of Fixit Epoxy Clay

Postby snrkl » Wed Sep 13, 2017 2:33 pm

Anyone have a line on what can substitute for "fixit" brand epoxy clay?

Is the the Tamiya Epoxy Putty a suitable replacement?

I am planning on using for fin fillets on an Apogee Aspire 29mm MD designed for supersonic flight...

Closest sounds like the knead it range from selleys?

Mixing your own from milled glass filler and epoxy could be another option, I use the west 403 stuff myself. A good fillet of that and the fin will likely snap before the epoxy gives way.

I have successfully used Knead-It as suggested by Rainier and it's also available with metal fiber in it for an insanely strong product. Super easy to use, two parts come rolled together into a special stick that prevents them from reacting somehow. Just slice a bit off the end and knead it till it's a uniform colour and apply. Only down side is it's fairly heavy compared to say JB Weld or epi-glue.

I tried several times to use Tamiya putty (white) and found it was super fragile (crumbled apart) and it also didn't stick to anything well. Not sure if I was using it incorrectly or it's just the wrong product for what we do.

Knead-it works great. Use gloves.

Thanks all for the suggestions. I looked into knead-it... it's quick setting (10-15 mins)...

For this one, I think I'd like a longer hardening time, so I've bitten the bullet and ordered some of the stuff from apogee. I'll report back how it goes...
