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. Even weirder, this "feature" is used in developing fingerprints in criminal investigations. http://www.ccs.neu.edu/home/feneric/cyanoacrylate.html R |

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. 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! |

IF the plasticizer was PVC, you can expect it to re-harden in a few weeks. PVC? PVC is the plastic, not the plasticizer? |

"JR North" wrote in message .. . 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. JR Dweller in te cellar Jeanette Guire wrote: 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? 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. Steve |

That begs the question of which is the best substance to glue a paperclip onto the camera body to fix the infamous Nikon Coolpix camera flaws? 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. |

No, it doesm't. It _raises_ the question, it _demands_ the question, it _prompts_ the question, but it does _NOT_ "beg" the question: http://en.wikipedia.org/wiki/Begging_the_question Thanks, Rich Grise, self-appointed chief, Internet Grammar Police. |

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. LLoyd |

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. Best regards, Spehro Pefhany -- "it's the network..."
