I've often wondered exactly what physical properties are supposed to be improved by mixing 2a to 1b. If it sits up harder is that necessarily a good thing for how a limb bends?

This is from their literature:

Heat Distortion Temperature:
At 1A:1B Mix Ratio*: 163°F (73°C)
At 2A:1B Mix Ratio*: 217° F (103 °C)

Yes sir, I've read that before. I am just wondering if any other properties are affected. Flexibility, longevity, ect.....

Is there any difference in the pot life with the various ratios?

you would be amazed how easily you can peel the glass from a limb

There are a few bowyers that have done test strips with both mixes just to see
. the 2-1 mix showed tearing of wood and not peeling was much better. I think another key thing is letting the glue cure at room temp or at least not putting it in the hotbox too quick. So all the air has a chance to work out before curing starts.

One of the walk the talk bowyers told me he quit having problems with air bubbles when he went to the 2/1 mix. I haven't tried that mix but I may soon .

If all the properties are better at 2:1...........then why do they even sell it at 1:1? Is the A side the more expensive part?

Hummm... I like the sound of better peel resistance!! I'll give this a try on the next set of limbs I make for myself!!

The A costs a bit more, I'd have to check but seems like about 3 bucks a quart. I've wondered why 1/1 is sold if 2/1 works better also Brad.. maybe bow application isn't the big useage of it ?

Also wonder why not sold separate in pints , only think I can figure is most guys that build lots of bows buy quarts or bigger.?

Ok I always use a bit more resin just because. Had very few problems. Those that did I have to say peeled pretty easy. I know a lot of the high end guys that go 1-1 and are happy with it. So I guess it is what you want to do. Piece of mind type of thing.

54* MORE temp protection is enough of a reason for me--the peel resistance is frosting on the cake

its not any different that 1:1 in the handling dept--I just order 2 A's and mix accordingly---

I use a 24grit belt to clean up a blank--the hardened snots are noticeably tougher--

if its harder for me to peel using a putty knife--its harder for it to delaminate on its own

See my gloom thread..... [saywhat]
