What I really hate seeing is guys hyping up epoxy with comments like we are experimenting with it.
These comments are just aimed at misleading the general public into the mind set that epoxy is that much harder to work with so we should charge more.
Blakstar is right It does take less resin to do a standard blank compared to polester resin,so the materials cost is minimal
Is it harder to work,come on guys get two standard blanks get standard 4 oz or whatever glass to do both boards,now go and glass each board one with epoxy, one with polyester.
If after doing this if you find one harder to do than the other, you did something very wrong on one.
Will these two boards ride any different ,the simple answer No
In both these cases the resin just provided the glass shell at a mill and a half thick ,both will be very similar in all aspects.
Try the same with a composite sandwich skin board,the epoxy will work better as it has better adhesion properties than polyester.
Now build two boards exactlly the same using sandwich construction,one with polyester one with epoxy ,forget the strength issues .
Both will take the same time to build,both can be bagged,one will have better durability over time.
Please forget the hype,its all just sticky stuff,none of it is hard to deal with.
Maybe we should start looking at prepregs,now there are a few steps that may baffle some?? Get the oven going boys!!
Final test get the two standard boards when they are brand new take them down the beach,now get the average surf crew to spot the difference.
They will look at the shape the ,weight,the shine etc,I very much doubt that they will spot the resin difference unless you drop some very leading hints.
For those out there that will say one will be yellower that the other,I will assume that a fresh batch of hardiner was used on the epoxy board so colour in the short term would not be an issue.
The short answer to all of this is that most standard construction board builders could switch to epoxy over night if they wanted to.
All it takes is a slightly different schedule to cope with the differing gel times.
The hard part would be training your staff to do something in a different time pattern from what they have been doing for the last god nows how many years.
For advise on that may be they should visit the local boatbuilders, many of whom switch from poly to iso to epoxy to prepregs as there custom clients demand. So they have staff able to change methods all the time.
None of it is new all these different resins have been around for a long time.
As some one else said in the US the laws are allready written so the change of method will be forced on to you,either change to epoxy or start learning how to infuse!
You decide which is harder for board production?
For the rest of the world ,styrene is not your friend, your goverment will make sure of that eventually!
