In Response To: Re: It's not really blush ..... (LeeG)

: Joe, sounds like it really is an amine blush as is normal for the few medium
: and fast epoxies I've used. Last week I made two test panels with 4mm ply,
: using fast epoxy thinned with acetone and lacquer thinner, there was
: blush, did the other side with slow epoxy and thinners, no blush.
: Given that the seller of CPES has not used it on strip hulls as mentioned by
: Pete it looks like the jury is out until hearing from someone else who has
: used it as you are intending.

It may not be blush. It is possible that the solvents in the CPES displace the natural resins in the wood and these rise to the surface.

I would also speculate that the solvents in the epoxy may come to the surface as the epoxy cures so the "blush" could just be the solvents.

I would expect that these solvents are compatible with any other epoxy you may want to use. They would just serve to thin the new epoxy and help its penetration.

This is all speculation. Joe should talk to the manufacturer and not count on our inexperienced guesses. It is possible the manufacturer does not completely understand every detail of the chemistry and molecular transfer of the product. But, all he needs to know is how to make it work, the details are unnecessary as long as he can make it work as advertised.
