Yeah, sadly I can say for sure if they have to hunt down a special glue, they won’t use it.
It needs to be something readily available for them to consider using it and I need to be able to send them a link on where to buy it.
I have never tried the purple or green either, I have used and broke free plenty of the red and blue though. :confounded:
This is what I was going by, look under the torque “break” header. Purple is about half the strength of blue.
@ Texas_Ace:
My suggestion was for someone to request what would be the appropriate adhesive from the Loctite site. Their site does have a technical staff. As for availability, that could be forwarded to Loctite; they may have a chinese supplier or, hell might be made there.
The purple is not very binding. It’s mostly for retaining fasteners from low vibrations. Doubt they ( Mateminco) would use a glue that is easily disassembled.
I had a catalogue of some of their industrial glues. I’d reckon this is now all on their web page. https://www.henkel-adhesives.com/us/en/about/our-brands/loctite.html?d8e433f99d33ce1953dcf6b425f4c49891bdc019.page=1
Edit: My previous experience with Loctite, the technical rep steered me to the products that most suited my needs. They sent me some samples and a list of suppliers. We did some tests (the technical engineers - this was a company endeavour) and called out some quotes. One supply house would deliver some 24 tubes of the stuff per month, a substantial discount based on a yearly consumption rate. The product was a permanent thread sealant (#577) (as in water piping) and then we went to a less permanent solution (#565) with the same mechanical / heat resistance.
So it would better to let Loctite give advice on the tamper (deterrent?) adhesive. They most probably have a supply chain for China - it’s the world’s manufacturer.
They glue parts in flashlights not only to keep people out but to keep parts from working loose for better durability. If the glue is too strong it’s hard to disassemble, if its to weak anybody can disassemble and parts could work loose. Hard to say where the line is for the purpose. Is it 53 in.lbs or 110 in.lbs or somewhere in between.
I decided not to buy several interesting Sofirn lights, as well as some from other sources, after hearing they might be glued up.
Ditto for recent Apple products and other companies’ glued devices.
Most companies nowadays with slim for factor phones ise glue, the repair guys use heat to break the adhesive

That’s what I was thinking while reading this. Because of salt and other chemicals for snow/ice on the roads any bolt that gets removed on my vehicles always get either a good anti-sieze OR pipe thead sealant applied. NOT a Teflon type. It stops the rust and would prevent impact/vibration loosening on flashlight parts. Save a horse, use less glue.
i don’t like glued because its very often that i find dust or smudge marks or something inside the glass lens, if the bezel is glued the problem is permanently there and it’s hard to live with!
You know… ’Maybe’ we are going about this all wrong.
Simon, of Convoy; does not glue his lights shut.
Instead of begging & hassling these other companies to “Not Use Glue”, maybe Simon should be contacted to see if he is in a position or be willing to do some of these BLF Special Projects.
If he is in a position and/or is interested, it would be one less thing we would have to worry about… the glue.
Just a thought… If a company does not want to do it “our way”, no problem; let’s just find one that will.
Just a thought……
Convoy is a really small company with Simon and just 4 or 5 employees. He’s not a manufacturer. He gets his light parts made from different manufacturers and assembles them himself.
IDK, Convoy is definitely not my first thought for doing a big project light.
BTW, this whole glue thread is to give input to Banggood on the MF01S. It’s not really about BLF project lights.
I understand that. That is why I said…. “If he is in a position and/or is interested.”
He makes a great light and who knows, he might want to expand. Neither of those questions can be answered by BLF speculation. The way to find out is ask him I think.
From what I read, a lot of the companies that do the BLF Lights are subbing out various parts also & then doing assembly. I don’t see a world of difference between them and Convoy. Except they might be bigger. But every company usually starts small.
The key is, to my way of thinking anyway; would Simon be able or even interested. Answering that question is the first step. And when I say “able”, I mean numbers wise. I feel sure is is “able” quality wise.
OK, I don’t remember reading that in the No Glue Poll; but ok. But “No Glue” is also a continuing concern/issue in every BLF Project.
IF, we can get one to listen; _‘just maybe’ we could get more companies to listen. If not, nothing really lost. Just find a company that will listen. :+1:
The last 3 flashlights I purchased were Convoy and directly from Simon. Customer service and No Glue were the most important deciding factors. I just ordered another C8+ from Simon because of their new ramping UI, my personal favorite. Sofirn/Utorch offer ramping UI, which is a different subject but as important as the glue issue for me.
I agree LarryLumens. I’m glad to see Simon getting into a ramping UI too. I’m hoping he will up his game even further in some cases. I really like Convoy lights. 
In fact at this point it is Convoy & Sofirn for me mostly. Both build great lights & have Customer Service second to none. . 
. Sofirn just needs to cut down drastically on glue. 
Oh yeah…. I like the Biscotti UI Simon uses also.
What’s this now? Is Simon making an e-switch C8 with a ramping UI? I checked his store, but didn’t see it. Maybe not out yet?
Ah, I see. Interesting Idea. Do you know the number to call? I might could try calling them next week.
I considered and contacted Convoy about projects a few times but as was said, he is just not ready for a big custom light at this point.
It is quite a large process for him to get a new light made and adds many layers of complication to what we already deal with, so at this time it is not practical sadly.
Would it be possible to use an adhesive which would soften with a blow dryer, allowing easier disassembly/reassembly? It couldn’t become runny, and would need to retain some measure of solidity. Flashlight on a sunny summer dashboard kind of thing.
This would be great if you know of something. The problem is finding the right product that is not expensive or hard to get.
@JasonWW, Yes Simon is selling a ramping UI C8+ w-SST40 led.
