The problem is if you apply a thicker blob the light can't pass inside. Ladies nails UV glue has transparent mask, it's probably better. You can get on a Chinese store locally.
-
I'm starting to love this channel :D
-
Thanks, I really like your quality videos. I like the thought that goes into your demonstrations.
-
Quite a lot of Quites 😁 interesting nonetheless 👍
-
Thanks Steve! I have been just using the regular kind.
-
Great videos, thanks.

Thick uv glue always cures slowly beneath. If the top layer is uv absorbing, not much uv gets to the lower layers. I have a convoy S2 as well. With visible light filter is a great general purpose uv touch. Visible light is not a problem for curing resins but in some cases it is. UV only pass filters are not that expensive, I have them on my uv flashlights that were not originally fitted with one.
-
For the benefit of those looking at how to use solder mask, let me share a tip that I've picked up from another channel. Hot air + uv light cures the mask in a matter of seconds.
-
I use the Convoy S2+ for UV mask and checking for counterfeit currency. If you use a hotair station at say about 350C and UV light, the solder mask will cure very fast in just a few seconds.
-
Dobra robota. Pozdrawiam ;_)
-
there might be more around UV curing, some resins have their curing triggered by the UV, but the curing would carry on without UV, others, it's the UV itself that does the curing, so you need to go full depth.
-
Useful stuff to know about. thanks
-
If you are not in a hurry just leave it to dry in the sun. I do use UV light and heat gun too at times
-
The black or amber syringes are used for UV sensitive materials. The black syringes are completely UV blocking. The amber syringes are only partially UV absorbing, but it it's not a problem as long as you don't store the tube at direct sunlight. Both types are available at ebay, aliexpress and other chinese eshops.
-
What about using a etching resist pen for a small mask fixes?
-
Saw a guy use a tiny paint roller - maybe 10mm x 20mm lg - to apply it evenly.
-
Now, that is interesting. I have the same solder mask, but it did not even try to solidify under 365nm, but 395nm worked quite fast. Maybe, my 365nm torch is just too weak. I will have to try it again with a thinner layer. (Insulating tape thickness is too thick )
-
But how well those can handle solvents like isopropyl alcohol, rubbing alcohol or Asento for example
-
Thank you.

Your UV torches curing results are weird. I bought two "51 LED UV Torch 395nm Ultraviolet Flashlight Blacklight Pet Urine Stain Detector" (eBay) and even the thick blob gets cured in just couple of minutes. Solder mask I'm using is LY-UVH900.
