I used the Touch N Flow liquid glue applicator for the first time and it went well. At the end of the use, I emptied the liquid glue for the applicator as it described and I thought it was all out. A few days later when I went to use it again I could not get the glue to flow (using extra thin tamiya liquid glue).
I suspect that some residue glue was left and may still be blocking the flow point.
What can I use to de-clogg this. I tried blowing air through (via airbrush) but no go. Is there a cleaning solvent that can be used to clear this?
I would be willing to bet that some melted plastic is on the tip. That is usually the casue when mine stops working. If that is the case try dipping the tip in some glue and then try you air method again.
Soak it in the solvent you are using. Just insert the needle end into your bottle and let it rest there for a minute or two. That should release what is clogging the end.
Remember never push with the applicator when applying solvent to a seam or a part.
When mine clogs, I soak the tip in MEK (Methyl Ethyl Ketone) which is available in hardware stores. I have a detached workshop, so I can deal with stuff like MEK. It’s not a material you would want in your house, or near flames, pets, and kids.
It’s one of the nastiest solvents you are likely to encounter, but it’s also a very good bonder and cleaner for a lot of plastics, including styrene, PVC, and epoxy and fiberglass. A handy thing to have if your situation allows.
