I use 105 and 206 and 207. This is for gluing in veneer strips for accent rings.

The yellow cup is 2 part 5 minute epoxy, System Three that I have used for years to glue in my brass tubes.

The clear cup is the West System. Quite clear, essentially bubble free - simply sat in the cup, no pressure pot. These samples were done last year.

I have not used it for casting.

You did not say what you were using it for. That stuff gets expensive compared to poly resins. If you are just coating woods you may want to use 205 or 206 hardener. More yellow but it gives the wood a warmer tint than sterile clear.

Now epoxy has a tendency to yellow with time. I have never done a long term study with the 207 and maybe someone has and can report back. The true way to test is without anything in the blank because background colors can trick the eye. How noticeable a resin will yellow is hard to say with the thin thickness we work with. Just some things to keep in mind. One of these days I may just try that experiment if no one has done it before. Good luck and just wanted to point out other options.

I used West Systems and loved the stuff. It seemed to be more forgiving than Alumilite as far as sticking to different surfaces. It is priced well over the other resins but it's not the same resin. It's not as brittle as P.R. and like I said it's more forgiving than Alumilite. It turns really easy and I never had a "Blow Out". It doesn't have the heat tolerance Alumilite has and doesn't quite have the shine the others do but it polishes very well. I never had a blank yellow but I always had trouble with the hardener yellowing in the can. It was good for a month and it wasn't noticeable in the blanks the second but the third month I didn't want to use it. I called the factory several times and they were nice and sent me a couple cans for free but I always had trouble. That was the only reason I switched to Alumilite slow.

I am using it for clear castings for pens and other turning projects.
Alumilite is not readily available in my part of the world and I am looking to purchase about 4 liters at a time.
I am able to buy west system 105 from a local fiberglass supplier so this seemed like the easiest option for me.
I also believe that it has a longer 'open time' than PR (although I must admit I've never actually tried using PR)

Thanks for the help and advise.

Good luck if you try casting with epoxy. I have read some negative comments for this substance compared to PR and Alumilite for casting.
