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 been 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 had changed
resin types. I was quite surprised when he stated that to his knowledge, Europa
/ Swift had not contacted the LAA about the change of resin. He went on to
say that as the original testing and type approval had been approved using
Ampreg
20, the LAA would need to look at the properties of 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 until 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?
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 again this week
and he stated that he had looked at the properties of both resins and had some
concerns over the glass temperature (Tg) of Ampreg 21 which fell short of
that for Ampreg 20. He went on to say that they had requested 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?
