Age of epoxy

[talonxracer]

I have some West Systems 105/205 down in the shop, the hardner(205) has become rather tan/brown colored, is it still ok to use, or should I invest in some more?

I mixed up a batch and am currently waiting on it to cure, but will the age of the stuff and the discoloring cause any strength issues?

According to the West Systems website, discoloration over time is normal. It will be just as strong as before, it just won't be good for coating if you want a clear finish over wood

yea i've heard stories of it going black, apparently its still good to use, just the colour. Of course nothings as good as fresh tho?
