New Blue Resin Research 2000 Epoxy!

General Discussion
1

I recently received a bottle of new Resin Research 2000 epoxy.The epoxy has a optical blue brightener that is supposed to make your board turn out whiter, as opposed to the clear 2000 that tends to finish off white.Has anybody out there used this epoxy?What were your results?Has anyone used colors or tints with this?

Hi -

I have a bucket of 1421 polyester surfboard laminating resin “with brightener” that also has a bluish tint. It does seem to be brighter on a surfboard but not sure if it’s actually due to improved clarity of the resin.

Resin Research is very clear as is. I’ll bet the blue tint stuff really pops on a clear board.

Sounds like a good idea, and very old. China (think plates, not the country in the other thread) and paper are sometimes tinted blue to make it appear whiter. A quirk of human perception that.

4

isn’t the blue-tint stuff their new “Resin CE” – formulated for use with polyurethane foam ???

It’s listed as 2000. I believe it can be used on anything you would use epoxy on, but not especially for polyurethane.

yes i’ve used it…as the resin cures the blue goes away and you have a nice clear glass job. pigments and tints work just fine…ET

Please note. If you use Resin Research epoxy on polyurethane, it must have a UV blocker added. If the UV is not blocked by the epoxy, it will destroy the underlying foam.

When people talk about epoxy just for polyurethane, they are talking about epoxies with UV blockers added.

is the UV additive something you can buy? I was aware you needed it for PU but why doesn’t epoxy just come with it already in it?

it’s so funny

Hi Dave -

I’ve glassed several Clark blanks with RR and to my knowledge. no UV blocker was added. They were glossed with poly so maybe that had some UV blocker in it? Anyway, I managed to break one and stored the pieces outside, in direct sun much of the time, for a couple of years. If anything, they were in better shape than any polyester glassed board subjected to the same treatment.

I’ve since used it to demonstrate how good the poly gloss adheres to epoxy… i.e. ding it with a hammer. The poly gloss might chip away a little but no worse than on a standard glass job. Under the poly gloss, the RR resin and foam don’t look too bad. I’d say the poly gloss turned darkest.

Just my .02

You would have had to add it. If you asked nicely there was a time they would add it for you. Maybe still true.

BINGO!

There have been a number of reports of polyurethane blanks getting semi-destroyed by direct sunlight under RR epoxy. If you add the UV blocker, or buy a variant of the RR epoxy with the UV blocker added, there is no problem.

There are lots of uses for RR epoxy other than laminating polyurethane blanks. so it is not sold with the UV blocker in it already (unless you get the new formulation for polyurethane blanks).

This did not used to be a problem when epoxies had to be painted…

The UV stabilizer most commonly used is called Tinuvin:

Greg (Loehr),

Can you chime in on this stuff? Justin dropped it off a couple of weeks ago and we haven’t got much info on it. Are you currently producing it? Who’s using it? Is there any pitfalls? Is it only in experimental stage? and so on and so on! Feel free to email me back or go ahead and post the info.

Thanks-

Brad

I am 100% sold on the resin research resin ( I have not tried any other brands), but I have noticed a gradual yellowing of my boards. From the posts I have read, I think it is from the additive F. I have not tried to lam or hotcoat without it. The yellowing is pretty suttle, in fact I don’t even notice it until you put a new board next to an old one. The same thing seems to happen with polyester boards. If the “new blue” makes a board that can remain white, I would be really stoked. I am waiting for Greg to enlighten us.

fiberglass hawaii’s epoxy has had this for a long time…comes out nice and white, but over time they still yellow…of course that could be from all the pinholes on my sanded finish p.o.c. backyard boards!

…bump…

my EPS boards are yellowing too fast.

Is the BLUE resin the product I need to be using???

Can I buy UV blocker from my RR sales guy???

You can get a 2 component clear coat or gelcoat to protect your boards from UV if your resin isn’t UV resistant.

“Sounds like a good idea, and very old. China (think plates, not the country in the other thread) and paper are sometimes tinted blue to make it appear whiter. A quirk of human perception that”

This is a trick I used waaay back when spraying all-over white on shaped polys…an ancient wisdom passed down the line.

A drop of blue in the white. Never really bothered to observe the difference however.

I got the UV blocker from RR. But this was some time ago.

I suspect talking to your RR sales guy may be more productive than asking here.
