Do you know what plastic the Nikon Coolpix 3100 camera body is made up of?

The reason I ask is that I had the same problem as all other Nikon Coolpix
owners did - namely the tiny plastic loop on the camera body breaks off so
the battery door won't latch so I superglued and epoxied a paperclip in
place. This worked but everywhere inside the battery compartment was fogged
and pitted with tiny holes from the Locktite cyanoacrylate superglue and
everywhere the Locktite Quick Set 5-minute Epoxy was wet, the camera body
melted.

Obviously I used the wrong glues and epoxy but nowhere in the reference
articles on how to fix the common flaw in the Nikon Coolpix cameras did it
say WHICH epoxy and glue were used!!!!

Since the crazy glue fogged and pitted the body and since the epoxy melted
the body where it touched and stayed wet, I must have used the wrong glues.
The epoxy says not to use on polyethylene or polypropylene - but what is

Don't know, but the minute amount of CA req to attach the repair part in
that location should not cause a fogging problem. Prolly you used *way*
too much. Also, there are less energetic CA formulas, like slow/thick
gap-filling, which do not go off with the fumes and heat that super-thin
CA does. Once more, a little dab'l do ya.

Hi

You can buy CA glue which is safe to use on plastics - try a model
aircraft hobby store.

Whether or not it is safe to use on your particular plastic is of
course a matter for experiment - but it's probably worth trying.

They recommend against PE and PP plastics because epoxy just won't adhere
to them -- both are _extremely_ resistant to solvents, and probably
wouldn't soften in the presence of any chemical you could obtain at
retail.

The CA "fogging" is because CA cements sublime at room temperatures, and
recondense on adjacent surfaces -- where they ultimately cure in the form
of a white film.

The only two plastics of which I'm aware that might be affected by the
plasticizers in some epoxies would be polystyrene and perhaps acetate.

Most likely, the plastic is a styrene/polybutadiene copolymer, which is
sensitive to acetone, xylene, toluene, naptha, and PVC plasticizers, and
which is one of the two most common injection-moulding plastics in use.

The problem must be with the specific epoxy you used. I'm not familiar
with which plasticizers are present in which brands, but would suggest
you use one with different properties. For instance, if you used a clear
5-minute epoxy (which tends to the soft side when cured), try using a
pigmented slow-cure type that cures hard, and try an entirely different
brand, as well.

I should have mentioned this: If the plastic _remains_ soft, then the
plasticizer is probably PVC or an adipate (organic oil). Dioctyl adipate
is often used to soften rubbers and styrenes, and its effect is
permanent. You won't get the plastic to re-harden after "drying" for a
spell. IF the plasticizer was PVC, you can expect it to re-harden in a
few weeks.

That must be what happened. The entire inside of the battery compartment
turned a milky white and changed from a smooth surface to a slightly
rougher surface. Even the yellow plastic sticker showing which way to put
the batteries seemed to get fogged up. Wierd.

I thank you for your help because I have only one camera to fix but there
are tens of thousands of others out there who will benefit from choosing
the RIGHT glue to fix the engineering flaw in the Nikon Coolpix series of
cameras.

I used the Locktite 5-minute quick-set two ingredient epoxy as shown at
http://usera.imagecave.com/coolpixfixer/fix_nikon_coolpix_3100_battery_latch_011.gif

For the record, the next person who tries the Nikon Coolpix camera repair
should use pigmented 30-minute expoxy.

Thanks for helping all of us!

The plastic seemed to only "melt" where the epoxy was liquid. I only fixed
the Nikon Coolpix 3100 camera yesterday so I don't know if the plastic will
re-harden but it seems OK now.

It was just anywhere there were drops of two-part epoxy, the body melted a
bit so I was worried the whole body would collapse.

I wish Nikon actually made good cameras or that the reviewers would
actually test the cameras ... if that were the case, this problem wouldn't
exist for the hundreds of us who have this problem.

It wasn't a cheap camera either. I fault the reviewers at dpreview and
Steve's DigiCam for very faulty reporting.

Jeanette,

Just a SWAG, but it could be that the plastic seems to melt
due to the reaction heat of the epoxy. ie: it DID melt.

Not that it's all that hot in the absolute sense, but the
location is very concentrated.

Thin thermo forming plastic don't take much to deform.

If it has stabilized, it's going to be ok.

BTW, the paper clip latch (Metal work, guys!) was a stroke
of pure genius.

I filed that one - just in case...

Hey, you know, this might be the answer! Thanks. It did seem to only happen
in the beginning, while the epoxy mix was still wet. I think this is what
happened. At least it makes sense. Thanks!

Why in the world didn't you just send it back to Nikon. They would have
probably chucked that one and sent you another. And another. And another.

plastic is clearly too weak for that loop.

I'd repair it with paperclip wire melted into place. zig zag the wire
for better grip on the plastic, then glue. GC Bond (used in electronics
repair) would be fine and doesn't hurt most plastics.

PVC is often used as a plasticizer in other more brittle plastics. It's
most of what's in plastic fishing worms, and what made them dissolve
tackle boxes until the makers hit on using polypropylene instead of
styrene.

HIPS is pretty good these days (and not much different in price from
good ABS or polycarbonate). It also molds very nicely, being a
crystalline rather an amorphous plastic. A lot of IR remotes are
molded from HIPS. It's not your father's polystyrene.
