I have a Idea to speed up the process of one of the products I make ..
I want to use west systems epoxy as the bonding agent.


I need the name of some material that epoxy will not bond to,.....metal or plastics doesn't make any difference .
From best to worst , cheap to expensive but I need be educated please .

I am making a tool and wish to use it over and over .....

Thank you in advanced,

HDPE ( about any polyethylene high or low density), Teflon, PET, Silicon rubber as used in cook ware, anything you coat with something like Bees Wax if you want a lot of flexibility in what you use and remember to re-coat it once in a while if it is on something it can wear off of and the heat doesn't get too high while curing, for metals mold release agents or silicon or Teflon sprays work to prevent it bonding with the metal and would probably work for most plastics or other non porous materials as well but needs an application each time it is used (a bit of testing here might be a good idea).

Thanks Mark .

That is a very informational link ...... thank you

I was thinking melamine or as JT suggested Delrin.
I can use both materials for other things in my shop if the don't work.


I am not sure which release agent I should try, When I contact the plastic company I will question them ....

Have you ever heard of TMI. Well we don't have that problem here. We need more information. :)

I understand what you are saying.
I don't really want everyone knowing how I make this certain product.

Sorry to be so vague..
 
Wax

Would a non-stick coating such a furniture wax work on the tool without contaminating the epoxy?

I think wax will be a issue because how tight the leather will be being pushed over the non stick tool I wish to make .
I think the leather will wipe the wax off, but that is only a guess .....
I am leaning toward a non silicon spray release agent .
Silicone in a nightmare in a shop that is doing epoxy finishes ...

I have been researching different waxes for years ,, ( Pool cue shafts )
Don't know if even synthetic paste waxes will hold up to the pressure/friction.
Soft to hard waxes and melting points
Paraffin, Bees wax, carnauba wax ( carnauba wax the hardest and has the highest melting point of all the natural waxes which at also all petroleum based . 185 degrees F .
Synthetic waxes are 230 degrees to 250 degrees and harder then carnauba waxes ...
I will be in a major plastics store next week ..
Buying stuff for several projects I have going on.
But my focus is getting this project going.

I've made my fair share of boat parts, using epoxy and PR. I use polyvinyl alcohol (PVA) as a mold release, spray it on your mold (Formica, King Starboard, etc) let it dry, cast. Washes off with water when done. Can be purchased through West Marine or Defender. I'd imagine shipping is expensive, I buy it locally.

Good luck!

Polypropylene...nothing sticks to it. I have a few pieces, one being a 90* piece shaped like angle iron , easy to clamp to and things slide right off. I use it to do my segmenting glue-ups. Got tired of laying out wax paper all the time. You can usually find misc. pieces at local plastic fabricators for a reasonable price.
