Google for alec tiranti. They specialise in moulding and casting but have a
range of two part resins with different characteristics. I found their
technical help line very good when I explained what I was looking for.

Steve,

I bought one of the Screwfix applicator guns and a pack of a dozen
cans. The can on at the moment was used four months ago until
yesterday when I was clearing a shelf and had to move it. I gave it a
squirt into a plastic bag to see if it was still ok and there was no
problem whatsoever.

search this forum (via google groups or similar) for the thread
"source of 2-part expanding foam" which I started last month. I got
some good answers there.

Do you mean foam glue as in a slightly foaming PU adhesive, or what most
DIYers would recognise as PU expanding foam filler? (if the latter, then
I would second Andrew's comments about getting a gun and the screw on
cans - just sooooo much better).

A good degrease and some high strength double sided tape works much
better on exterior trim.

If you really want something similar to expanding foam then Titebond
Polyurethane expands and sets in a similar way - but significantly
slower and as there is no butane/CO2 being injected into the PU there
is a much reduced chance of sticking a canoe to your staircase.

Excellent suggestions guys, I'll look into them.
Many thanks.

Evostick Serious glue is pretty good for many trim bits on cars that other
glues don't work on. Especially plastic to plastic.
But it's not quick acting - needs supporting for about an hour and 24 to
cure properly.

Do you mean the stuff featured here?

A friend of mine once built a canoe. He spent a long time on it and it
was a work of art.
Almost the final phase was to fill both ends with polyurethane
expanding foam.
He duly ordered the bits from Mr Glasplies (an excellent purveyor of
all things fibreglass) and it arrived in two packs covered with
appropriately dire warnings about expansion ratios and some very good
notes on how to use it.
Unfortunately he had a degree, worse still two of them. One was in
Chemistry, so the instructions got thrown away and the other in
something mathematical because in a few minutes he was merrily
calculating the volume of his craft to many decimal places and the
guidelines got binned as well.
He propped the canoe up on one end, got a huge tin, carefully measured
the calculated amounts of glop, mixed them and quickly poured the
mixture in the end of the canoe (The two pack expands very rapidly).
I arrived as he was completing this and I looked in to see the end
chamber over half full of something Cawdors Witches would have been
proud of. Two thing occurred to me, one was the label which said in
big letters: "Caution - expansion ration 50:1" (or something similar)
and the other that the now empty tins said "approximately enough for
20 small craft"
Any comment was drowned out by a sea of yellow brown foam suddenly
pouring out of the middle of the canoe and the end of the canoe
bursting open. My friend screamed and leapt at his pride and joy which
was knocked to the ground as he started trying to bale handfuls of
this stuff out with his hands.
Knocking the craft over allowed the still liquid and not yet fully
expanded foam to flow to the other end of the canoe where it expanded
and shattered that end as well.
A few seconds later and we had a canoe with two exploded ends, a
mountain of solid foam about 4ft high growing out of the middle, and a
chemist firmly embedded up to his armpits in it.
At this stage he discovered the reaction was exothermic and his hands
and arms were getting very hot indeed. Running about in small circles
in a confined space while glued to the remains of a fairly large canoe
proved ineffective so he resorted to screaming a bit instead.
Fortunately a Kukri was to hand so I attacked the foam around his
hands with some enthusiasm. The process was hindered by the noise he
was making and the fact he was trying to escape while still attached
to the canoe.
Eventually I managed to hack out a lump of foam still including most
of his arms and hands. Unfortunately my tears of laughter were not
helping as they accelerated the foam setting.
Seeking medical help was obviously out of the question, the
embarrassment of having to explain his occupation (Chief Research
Chemist at a major petrochemical organisation) would simply never have
been lived down. Several hours and much acrimony later we had removed
sufficient foam (and much hair) to allow him to move again. However he
still looked something like a failed audition for Quasimodo with red
burns on his arms and expanded blobs of foam sticking everywhere. My
comment that the scalding simple made the hairs the foam was sticking
to come out easier was not met with the enthusiasm I felt it deserved.
I forgot to add that in retrospect rather unwisely he had set out to
do this deed in the hallway of his house (the only place he later
explained with sufficient headroom for the canoe - achieved by poking
it up the stairwell.
Having extricated him we now were faced with the problem of a canoe
construction kit embedded in a still gurgling block of foam which was
now irrevocably bonded to the hall and stairs carpet as well as
several banister rails and quite a lot of wallpaper.
At this point his wife and her mother came back from shopping......
Oh yes - and he had been wearing the pullover Mum in law had knitted
him for his birthday the week before.


Very old but always worth re-telling.
