Super Jet Foamed Epoxy to Replace Foam Urethane in Tray?

[BrightE's]

I was stumbling around the interwebs and came across a company that makes a low-density expanding epoxy foam and it crossed my mind that this might have some application in tray foaming for jobs not requiring large amounts of sculpting.

Some of the foam details form the site are below:

• Buoyancy.
• Excellent resistance to water.
• Results in a low density foam.
• A rapid expansion.
• A slow hardening of the foam.
• No use of fillers such as microballoons.
• Two part system.
• Adheres to numerous materials.
• Can be poured onto and co-cured with prepregs or other epoxy laminates.
• Uniform density.
• Does not contain CFC’s.

In addition to providing buoyancy, there would be a presumed large structural increase as well over urethane.

Has anyone messed with this stuff? The company's own demonstration video is of them casting a sailboat rudder, and the majority of the imaged applications are nautical in nature.

The more I read the more it seems like the stuff's density might be a lot larger than urethane foam's, meaning weight weight weight.

Check the price, there are several high quality foams that do not soak up water but too expensive for our use.
