Do not ever confuse squishy like foam rubber with a "Tough" material like a highly engineered structural foam. Let me get this straight the...
No it does not work that way.
Cat here you may want to rethink the Squishy thing. http://www.youtube.com/watch?v=DRzyw0Jo8Zg
No at 24 hour ambient cure I would assume the elongation to be greater,think about that, What are you doing a clear casting or a laminate? a Clear...
On the ductile cores normal test methods do not work as they indicate movement as failure,that is exactly what these materials are designed to do.
Why would you have too, are you making a hot solvent tank and worried about the service life in the chemicals ? That cure is for a clear casting...
There is a infusion version on the 411 also what are you talking about? 5-6 % elongation is plenty are you wrapping the glass around concrete...
HUH?? The Derakane Momentum 411-350 Epoxy Vinylester should be 6% on the high side, if memory serves, it comes in a infusion grade as well.
Yes Sir ,every resin system we used I was not afraid to call the lab they spoke a different language but I eventually got the info, Now the...
I got a little different information on this from SP engineers, looking for both ends of the heat range and their recommendations on the process.
Thermoforming ,Depends on who you talk to.
A-500 foam 65 C would be a good starting point, maximum would be @120 C there is a learning curve here and people get away with heat guns in some...
Some chemicals are very very bad,I prefer to buy my resins neat so that entailed keeping cobalt and DMA in the building which lived in a seperate...
Most of the Vinylesters we used have elongation in the 6% range and work just fine, I build highly stressed cored structures and have done well...
LOL or your life.
I usually do a test on the prepped mold surface with the production Gelcoat that we would be using.
You can soften the plastic (Thermoplastic)with excessive heat and the gas (nitrogen) bubbles expand,There is no chemical reaction.
Simple you do not put it there to begin with,This is the reason I use a pressure fed Roller,large areas can be covered quickly ,Now on a heavy...
Hoyt thanks.
How are you planing on dispensing the epoxy on the laminate and do you have a helper??
