| arlen holder <arlen@arlen.com>: Feb 02 08:15PM The glass-plastic-sandwich screen cracked on one mobile phone so I removed my screen and put it on the other mobile phone (we both have the same LG Stylo 3 plus). It keeps falling off as the original sticky glue on the top and bottom edges doesn't have enough remaining. I do _not_ want to cover the original glass in liquid uv-cured glue, which is what is likely the best from a refractive-index standpoint. I just want temporary stick glue like that which came with the original glass/plastic sandwich glass. I went to both Home Depot & Lowes, neither of whom had anything that they thought would work to solve the problem. I even tried Fixodent, which worked perfectly but only for a few days. What temporary sticky glue would you suggest that I can get at a local hardware store like Ace, Home Depot, Hardware Freight, etc.? |

That adhesive was likely developed just for that purpose. If you must know, Contact 3M. There's no company IMO that knows more about adhesives than them. Other than that, why not just buy a new protective screen? They're like 3 bucks shipped and come with the adhesive already applied. |

Welcome to the sci.electronics.repair.philosophy newsgroup. If it were easy, it would not be fun or interesting. It would also not require a newsgroup full of "experts" to explain how things should be done. Sometimes, the hard way is the best way while the easy way is an invitation to future problems. Also, there is no single right answer for fixing anything. There are always two or more ways to do anything. All a right, although some are more right than others. <http://www.learnbydestroying.com/jeffl/pics/repair/slides/Iphone4-cracked-screen-01.html> -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Hi Jeff, As you ascertain, the point of the question is to _learn_ about the type of glue that has the following qualities - which can be used elsewhere in sceitneific repair... 1. It's 'temporary' (but firm enough to stay in place); 2. It's 'sticky' (more than the Fixodent was, but far less than epoxy is); 3. It's 'viscous' (it can't _flow_ because it will cover 4 small top ports) 4. And, it adheres to glass. Hence, for example, all _permanent_ solutions (e.g., cyanoacrylate) fail. The Fixodent failed only because it wasn't rigid enough (i.e., not sticky). Note this glue does _not_ need to have anywhere near the refractive index of glass because the LG Stylo 3 Plus has a black 1.2 centimeter frame on both top and bottom. That means there's plenty of room for a "viscous" sticky temporary glue. The only question,. from a chemistry standpoint, is which glue is that? NOTE: I saw your other post, where I haven't delved into examining the links yet, where again, matching the refractive index of glass isn't the issue here as it might be with most screen reflector glues. |

Learning about the type of glue is what this question is mostly about; although the final repair is a secondary goal (as is the ability to repair in the future, using the knowledge learned about the type of glue). Given that... There are two issues here, each of which is completely different: 1. This question is about where to obtain a specific type of "glue" 2. You seem to have fantastic sources that I am not privy to (yet). To clarify those two completely disjoint observations... 1. Why even have a "repair" group, if all you do is "replace"? 2. You must have far better sources than Amazon given the price you quoted. For the types of glue, I'll defer a response until I can go through Jeff's purposefully helpful response in detail (with respect to chemistry). The _best_ I can find on Amazon, sorted by lowest price, is: <https://www.amazon.com/s/ref=sr_st_price-asc-rank?keywords=protective+screen+lg+stylo+3+plus&sort=price-asc-rank> The cheapest, is more than twice what you quoted, although I'm sure, in bulk, we can find cheaper (but I only need one, or maybe two, for now). I simply ask where & how you found the protectors for 3 bucks shipped? |

You have a 12 mm wide area to adhere the spread sticky stuff on, so have you tried using double-sided sticky tape? I'm suggesting the thin, transparent types that look like sellotape, not the thicker foam tapes. These tapes come in 6mm and 12mm widths and can be peeled off, though with some difficulty if you use the stronger bonding types. FWIW I use the latter to attach Mylar seals over the aileron gaps on gliders. One strip of 15mm wide tape on the wing in front of the hinge will keep the Mylar firmly attached for several years if its rolled down well and its leading edge has a strip of gap tape over it to keep dust and moisture from penetrating under the mylar, yet isn't too difficult to get off and replace when it starts to loose its grip. -- Martin | martin at Gregorie | gregorie dot org |

There may be a safety requirement to discharge across a safety barrier, without affecting normal leakage, for static discharge. RL |
