Epoxy number three please.....

So now i'm half way through the final gallon of the good stuff (RIP Reactive Resins) its time to look for its replacement. Thought i was gonna go the MAS route but at £160 delivered for 6kg thought better of it, i reluctantly looked at West Systems and that's £140 delivered for a 'B' pack so over to google to find my new epoxy.

I found a company called Polyfibre but couldn't find any tech sheets of mechanical properties or specs so ruled that out which left me with Easy Composites & their EL2 epoxy system. The main objective was to compare mechanical properties with both West's and Reactive's products I've been using over the years.

Interestingly EL2/AT30 is superior to Wests 105/205 combo in terms of mechanical properties and a quick chat with their tech guy confirms it's good with all filler additives including longtime friend of the show Cabosil and doesn't blush to any great extent so put an order in. 

Cost-wise it's pretty much the same as Reactive's epoxy, works out at around £15 per kg delivered which is better than West Systems at nearly £24 a kg delivered and Mas at £27 a kg. So from here on in (or until they go broke too) i shall now use EL2 epoxy & AT30 Fast Hardener for the project. 

Knowing what i know now, when i took a call from Reactive Resins as to whether i wanted anymore resin, me saying no then them going belly up a couple of months later i may stockpile enough EL2/AT30 to get me through to the end as companies of all shapes and sizes are going pop daily. Initial impressions of the resin are good, low viscosity which i like and pretty clear too, i shall report back after I've knocked it up in different additives. I have enough reactive epoxy to get the heads and R/H main bulkhead in then will switch to the new kid.

At the moment work's progressing although talk about the wrong time to run out of nitrile gloves and a few other bits of PPE, what i pay £6 for 50 pairs of gloves now costs around £25!  Still I have enough to get the bulkheads up front in, the left hand side is done, i now need to build up the curved bulkhead, sheath, paint then fit and same with the R/H main bulkhead.
