Thanks in advance

Mike

Your local UAP (automotive jobber) had Dupont Corlar 810R which is a
chromate bearing, self etching epoxy primer. We settled on this after
discussing it with the Dupont factory tech reps. It came down to what
can we buy from local suppliers which is suitable for the application.
We are aware of other builders coming to the same conclusion.

As with most other paints these days a charcoal respirator is NOT
enough, you must use a fresh air system and personally I much prefer
this to the typical mask.

Cheers,

Dave

Mike,

Another one you may want to look at is trio-prime from Martin Senour. It is
also self etching, works good with HVLP guns. My tech counselor recommended
it to me.

I'd be interested in a reference to an MSDS or anything authoritative
that shows that paint such as epoxy has anything in it that will get
through an organic vapor (charcoal) mask. I like the fresh air mask when
it is hot but I prefer the freedom of a filter mask for most jobs.

Certainly Urethane paint that contains ISOCYANATES absolutely requires
fresh air fed to a breathing mask but that is the only one that I know of.

The polyfiber web site should show the Canadian distributors of their
EP420 epoxy primer. I know there is one on Davand beside Toronto airport
(but it is pricey even with their 20% discount) and one in the Okanogan
who advertises in the RAA magazine.

There were two painters at the Rebel meeting yesterday that mentioned
how good automotive paints were for aircraft now that some are
formulated for use on aluminum. Talstrip by Marhide (spelling??) was
a recommended paint stripper available through auto supply stores.

Speaking of the meeting: other tidbits were that in Canada the aircraft
data plate only needs the builder's name, model, and serial number on it
now. Also it was highly recommended that all paper work have the exact
same name on it to avoid long delays after the final inspection.
Apparently the bureaucrats don't comprehend that John Doe might be the
same person as J. Doe.

One thing that would be nice IMO is a pimer that is slow dry/cure. It seems
EP-420 is better than some (such as the NAPA rattle can etch/primer -- aka
Martin Senour i think). Basically, when wanting to assemble parts with wet
primer, it would be nice to have a lot of time before it hardens. I've made
some parts where I put on a layer of chromate and clecoed almost every hole
so that things would cure flat and flat, and allow time to rivet later. As
well, I keep a rattle can handy for quick spots where spraying is eaiser than
the little brush.

Brian@Murphy had once mentioned a primer from Sherwin-Williams. Anyone know
about that option?

Was just on the phone with Brent.... clearing up some order issues... and
asked him what MAM was using these days.... since EP 420/430 is getting
financially rediculous this side of the border and this is what he just sent
me. Wayne
............................................................................
Being an old painter type I feel I have to toss in my two bits here. Most if
not all suitable primers on the market now will require the use of fresh air
equipment. Manufacturers erring on the side of safety are recommending
nothing but. I think your people out there may find it very hard to procure
the polyfiber primer. They will no longer ship this product to us (We are a
distributor) Our volumes on the 420 and 430 are not high and the DG shipping
on this is prohibitively expensive. A quart that would retail out the door
at $53.50 Canadian for the primer and $22.80 for a pint of the catalyst (Mfg
suggested retail) end up costing close to $108 and $50 respectively when you
add in the DG shipping costs to us. I personally find that a little hard to
swallow knowing what it is retailed for across the border, but you can't
expect any retailer up here to swallow that kind of a cost. Here we use
either Pacific Endura 2 part urethane primer EP2C pt A and B or the Sherwin
Williams CM0483660 Pt A and CM0120888 Pt B (Gallon part numbers). I have
personally used both and they do the job very well. The Endura product is
about $30 a gallon cheaper and is available in quart quantities, you should
be able to pick up this product at Acklands. I am pretty sure that the
Sherwin product will be available there, but believe that it can only be
purchased in gallons, and at this size it comes very close to $200 Canadian
for the kit. If I come across anything else in my daily searches I will let
you know.
