Giddy,

I have been using West Systems for non structural areas of late, and had the opportunity to speak to a Long Eze expert at Chino, LA. He told me that he wouldn't use West Systems for structure, and I recall that is reflected in the ACS manual. Other than SP Systems which is not available in Australia, to,clarify the original,SP20 is superseded and even though it has a picture of a Europa on their literature, it isn't approved (go figure), I would like a reminder on other approved Epoxies please.,this fellow swore by EZ Epoxy. Any advice much appreciated. The West Systems has a greater viscosity, a shorter pot life, and doesn't wet out as much. 

Regards

Tony Renshaw

Hi Tony

That was quick let me know if you want any other dimensions.

The Europa build in England is only approved using SP Gurit Ampreg 21 which 

replaced Ampreg 20 in 2010.

According to an Ampreg 21 leaflet I have on file, they have an office 

supplier at Unit 1A/81 Bassett Street, Mona Vale, 2103 NSW,Australia. 

Tel+61 [0] 2 9979 7248 Email sales-au(at)gurit.com

I would be very sure before using anything other than an approved system.

By the way Ampreg 21 is horrible stuff nowhere near as easy to use as 20, 

but was introduced to satisfy Health & Safety !

Regards

Richard

Here in Canada/USA we use aeropoxy as supplied by the Europa dealer at the time.



Fwiw,

Cheers,

Hi Craig,

Thanks for the detailed reply. I built my classic foam filled winged Europa with Ampreg 20, and I am sure it is a toxic product.  I got flu symptoms and often a headache after using it. The West Systems 105 I too have been using on smaller jobs, and I find it a far healthier product to use. I have no effects, and only hope I did myself no harm with the Ampreg 20. It has been that long ago I used it that I hardly remember, but I do recall wearing my respirator for all the big layups. I dont mind the West Systems with the exception I believe it doesnt wet out as well, also I believe it may not be as strong in shear, easier to pry off a substrate (unzip as I call it). Still, the forces should normally not be shear forces that "peel" a layup off a substrate, so the effective strength is surface area based, not point load based with a perpendicular load pulling th le layup up and away from the job. I just got the wind put up me when the Long Eze expert said he would not use it as a structural resin. I interpret that as a system that entraps "loaded fibes" in a matrix, and as my smaller layups, like the door reinforcement ones, U believe the West should still be ok. I am though going to look into Aeropoxy and any other the list recommends. Problem is as you know,

In Aussie it is hard to get certain reains systems, and in the old days I would get Ampreg 20 with half its shelf life remaining, straight from the manufacturer/agent. Thanks for the input.

Regards

Tony Renshaw

 Tony, I believe most of the other builders switched to west 105 system, we

 have the West systems importer on the goldcoast here and I have spoken to

 them a few times, the spec sheets they gave me for 105 indicated that it had

 a higher rating

 Than the ampreg epoxy system, yes it does have a shorter pot life, but I

 didn't find that a problem. I just mixed smaller batches and was a lot more

 practiced  with my glassing work when I ran out of the ampreg, one thing, I

 always had problems with the ampreg causing A LOT of swelling on any skin I

 got it on a few hours after the event, I have never had that happen with the

 west epoxy, mind you I did get virtually all the glass work done with the

 ampreg, I have used the west system for

 "mods" and the filling/sanding stage, west also had some other systems

 equivalent to the araldite 420, but it was VERY thick

 The factory told me, so would not be suitable for a lot of the stuff the 420

 is called for

 

 Regards

 craig
