The Airex R63.80 I used was brownish yellow, that was used in the Hull shell, Bulkheads and Deck, the Green color I do not know about.there is airlite and a whole host of foams it could be.

yeah the original airex is r63.80, but when i called to get some new stuff, the lady said that the green variety is denser and just to be safe she was going to send me that.

The green material is crosslinked ,she evidentially was confused about the application.

haha and thats why i wish i was in contact with you before i started the project. but the piece is in place and the boat is back together. oh well. sorry for getting off topic.

No you are like family, never a problem!

Someone say Airex Powerplay race boats??

I will check out back and will put you in touch with the right people to get some samples.

way cool Steve, i have a project i need to step it up a bit on. Thanks a bunch.


how does the use of a scored sheet as opposed to a flat/rigid sheet effect overall properties/strength? I was always under the assumption a scored sheet would be stronger because of the ability to form that little bridge at all the bonds within the scores. Is that a flawed theory?

Dave There are a couple schools of thought on that,One is you windup with a heavier structure in the end and the million razor blades of resin detract from the physicals of a dynamic core.

I have used knife double cut and triple cut core without any problems
It forms very well ,Speaking of bonding the R63.80 Airex had the highest peel strength of any core,This was one side bagged in corebond (1 MM bond line)seems to have some resin "friendly molecules" in the ester world.

Ah yes !!!!

Thanks Steve !

Brings back the memories....
