What plastic is the Nikon Coolpix camera body made up of (why did glue melt it?)
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!!!! Here is a photo of the Nikon Coolpix camera body BEFORE it breaks http://www.dpreview.com/reviews/Niko...ompartment.jpg Here is a photo of Nikon Coolpix camera body ultimately broken http://files.myopera.com/mcduret/blog/IMGP0065b.JPG Here a user fixed the Nikon Coolpix camera body with a paperclip http://www.uthunter.com/images/Nikonfix.jpg Here a user fix the Nikon Coolpix camera with a tripod http://files.myopera.com/mcduret/blog/IMGP0070b.JPG Here is how I fixed the Nikon Coolpix 3100 camera with epoxy http://usera.imagecave.com/coolpixfixer/ Here is a photo of how Nikon fixed the flaw themselves http://www.scaredpoet.com/images/E7600_batterydoor.jpg 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 the Nikon Coolpix 2100/3100 camera body made up of? |

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. Regards KGB |

The epoxy says not to use on polyethylene or polypropylene - but what is the Nikon Coolpix 2100/3100 camera body made up of? 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. LLoyd |

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. LLoyd |

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 http://usera.imagecave.com/coolpixfixer/ 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 http://usera.imagecave.com/coolpixfi..._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! |

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... Richard |
