I am not sure if it helps, but I have been playing with the Hydropel ro15 vinylester resin. That runs about $40/gal in single gallon quantities, if I recall.I don't know the viscosity offhand, but it is very thin and works much easier for infusion than the epoxy resins I have tried. The only infusion specific epoxy resins I have seen are way too expensive for me.

Does anyone have any sources for Infusion epoxy here in the US?  What I'm currently using is...

In the small quantities I use (so far) a kit is about $69 for 1.5 Gal (5.7 Liters).  This epoxy is not labeled for Infusion.  The resin has a viscosity of 600 cps.  The hardener has a lower viscosity, but I haven't been able to get a number from them.  Depending on which hardener, the pot life can be up to 30-35 minutes at 80F (27C).  It does not require an elevated post cure.

 

I just checked MAS which is marketed as an Infusion epoxy.  It also has a viscosity of 600 cps for the resin and 250 for the hardener.  Which seems to be the same... except their price seems closer to $180 for the same 1.5 Gal kit.

 

Does anyone have anything... of lower viscosity or generally easier to use for infusion and/or lower cost?
