Default What plastic is the Nikon Coolpix camera body made up of (why did glue melt it?)

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.


Most likely, the plastic is a styrene/polybutadiene copolymer, which is
sensitive to acetone, xylene, toluene, naptha, and PVC plasticizers


This is good to know for the next person who does this repair

if you used a clear 5-minute epoxy, try using a
pigmented slow-cure type that cures hard, and try an entirely different
brand, as well.


I used the Locktite 5-minute quick-set two ingredient epoxy as shown at

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!


PowerPoxy makes a plastic bonder. It comes in a double syringe, like
5-minute epoxy. It is said to work on all hard and soft plastics. It
doesn't say that it doesn't work on polyethylene and polypropylene,
but I'd be surprised if it does.

Color is kind of an ugly opaque amber.
