The first 3-4 boards I many moons ago with RR2000 turned a virbrant yellowish orange within three weeks. I did not get pink. They looked like shit, but were strong. I thought it was from using tap water with my spakle or from cold weather. When I finished all of the resin I got, there was about a cup or more of resin left over. Herb Spitzer got a hold of one of those yellow boards a few years back from a friend.
Check out the test panel thread. I have seen water do that too though. We always used distilled.
Test the Resin Greg ! What do you have to lose ? Back up all your posts and claims. Don't have your friends come on here and post RR is magical. Test the resin !
I've done the tests. There sitting here in my office. I'll be happy to post it if you get permission from my competitors. If you don't then no way. Wouldn't want to appear bias .... course that probably wouldn't occur to you.
I don't get it? I must be really stupid? How come we have done 100's of boards with RR and lately the KK and never have we once got pink?
Over 500,000 surfboards have been built in 30 years of business with RR resins and not one pink board. One shop gets 25 boards that turn pink and we're who they point at?
I ran out of denatured alcohol that I use to wipe the baste coat with to improve adhesion before the sanding coat. All I had was acetone. As a matter of safety in using acetone I used a clean rag. The only rag available that I knew was clean was an old black cotton t-shirt.
The acetone bled the dye out of the shirt and got deposited in the weave of the surrounding lammed cloth. The basted portion was clean but the surrounding lamination was a disaster. The color was so faint that I didn't catch it until the board was sand coated and sanded. Had to go back and sand the board down into the color and redo both boards. That was the last time I ever used a rag or cloth with any type of color or contamation in the rag.
Not seeing the boards in question I'd bet that acetone was used in some step of the process. If it is splotchy my guess is acetone on a red rag. If the color is uniform then the acetone picked up a contaminant that was mixed into the resin.
In any case acetone and epoxy is not a good mix.
Kind of feel bad for the guy. He's screaming in a room full of deaf people.
Howzit DMP, go back a few posts and it tell that they were using acetone as a thinner. Aloha,Kokua
Just thought this example of ancient chemistry might require a little bit of consideration:
Copper red glaze on porcelain. Darker red occurs under longer periods of sustained reduction. The most vibrant examples require a solution of less than 3% of Cu2O along with other trace metal oxides like tin, zinc, sodium, potassium, etc. WTF does this have to do with anything? . . .
Most water supply pipes (until quite recently) in the US are copper. Soft (salty) water through those pipes creates and transports Cu2O and other metal oxides from that alloy pipe in solution. Aren't the blowing gasses used in foam production typically reduction agents? Don't they all gas-off when heated, say by exotherm from curing resin or during post curing cycles? What is it that most people use to thin their spackle with and where does it typically come from?
Just a thought. Nobody here believes that RR is magical - just way better than the other crap out there. We only post to share our experiences with the product and show some gratitude toward someone who could have stopped developing the technology years ago, but who instead continues to improve upon it and is available on a daily basis to guide foible prone consumers.
used the kwik kick epoxy today for the first time and i loved it...my laps were awesome, and my hotcoat came out great...
