I use a syringe with an 18 or larger gage needle to dispense HH-66. Also, think of HH-66 as a chemical weld as opposed as a glue. HH-66 is designed more or less to degrade the vinyl with acetone so it bonds together. Also, try looking at double impulse hand held crimp heat sealers. I got mine off Amazon, works great with this type of vinyl. I only use HH-66 on curves or internal items.
Hi Becky, I'm learning to make inflatables too. Can you not use a sealing iron or a soldering iron to seal up the vinyl? Does it not work with clear? Just curious. Love your videos!
Good question Katy, and this is worth an experiment. However the reason why I didn’t try a soldering iron or other heat tools is because I assumed their temperature range was much too high and would end up singeing the vinyl instead of just fusing it, like the roller in the video. If one could find, or manufacture, a flat iron / heat crimper that is programmable to vinyl’s specific glass point, that’d be best. The programmable tool that comes to mind is a sous vide, but could aliquid transfer the heat? I’d wager it would be more efficient to design a tool and mass produce it via Kickstarter than to attempt that experiment! Please do reply with any further speculation or counterpoints!
PS I just realized this isn't the heat experiment video! Just in case you missed it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4JxS91OddJA.html @@katyb3869
Is there a way to dye vinyl? I'm contemplating vinyl spray paint since my thoughts inflating and deflating a Christmas blowup would cause stress fractures which would lead to the paint cracking and peeling off
