RR epoxy formula for 6% elongation

Which formula would you recommend?

I ask b/c published specs for s-glass is about 5%

  • thanks in advance

I’ll second that, specifically do your more flexible formulas have different elongation numbers?

are there info sheets?

hi wells…greg suggested using 2020 for that app…regards

I don’t have the exact numbers but 2020 does run in that area. The 2020 has been around for many years and we just got used to using it through experience and just kinda know where it fits. We never felt that knowing the exact percentage was all that important because it always comes down to trial and error anyway. The fact is that we never use anyone elses resins, since we can make anything we want ourselves in the lab, so comparison is always with other things we are doing. The 1980 and 2040 are very new and now that there are four it would actually be nice to know the exact numbers so we could have a comparison with other systems. Something I’ll have to work on.
