John and all I had run out of good hardener and could not get more when the
Ampreg stopped -
Hence had to dispose of about 10 containers!
Didn't like that!

I believe I was the first UK builder to use Ampreg 21. I ran out of Ampre
g 20 while doing finishing work. Europa eventually supplied me with Ampreg
21 after talking to the LAA who gave informal approval.
I suspect that someone at the LAA said it was OK to use Ampreg 21, having
been told that it was going to be used for finishing, and that Europa misu
nderstood this as general approval for Ampreg 21 as a replacement for Ampre
g 20.
Like others who have reported on Ampreg 21 I was not terribly happy with
the stuff. No doubt better for the environment (and for my health), but I p
referred working with Ampreg 20.

There may be a problem for UK builders using Ampreg 21.
Having noticed that the latest build manuals on the Europa website had,
for some time, listed Ampreg 21 as the supplied resin and after confirming
with Martin Armstrong at SP Systems (Gurit) that Ampreg 20 had finally bee
n stopped, I ordered some Ampreg 21.
As I am mid way through a project, I telephoned Andy Draper at the LAA
before Easter to find out if I needed to record in my build record that I h
ad changed resin types. I was quite surprised when he stated that to his k
nowledge, Europa / Swift had not contacted the LAA about the change of resi
n. He went on to say that as the original testing and type approval had be
en approved using Ampreg 20, the LAA would need to look at the properties o
f Ampreg 21 to decide if it was a suitable alternative. Although he stated
that he did not foresee there would be a problem approving the alternative
resin, he left me with the impression that it would be unwise to use it un
til it had been approved and suggested that an update to the Europa TAD on
the LAA website would be needed and that I should look out for this.
Has anyone else been told this=3F
A telephone call to the Europa office was met with equal surprise that
the LAA were questioning the use of Ampreg 21. I telephoned Andy Draper ag
ain this week and he stated that he had looked at the properties of both re
sins and had some concerns over the glass temperature (Tg) of Ampreg 21 whi
ch fell short of that for Ampreg 20. He went on to say that they had reque
sted further details from SP Systems.
I would guess that a lot of builders are already using Ampreg 21 on the
basis that it is listed in the current build manual. This could be a big
problem for UK builders, especially as it is the LAA who ultimately have to
sign off the build and issue a permit.
Have any other resins been approved for use in the UK=3F
