Since the last video I have been seriously thinking about making these powders as a hobby. The problem is that I want to mix them with some paint or resin to get a more permanent application. I know this needs some research but any ideas about where to start?
- analog31 3y agoA challenge is finding a resin that doesn't re-absorb the IR, which most materials do, even fairly thin layers.
- retrocryptid 3y agoWatch the video.
- fbdab103 3y agoEven if they work, I would question long-term stability. Would the panel still be productive after a year in the sun/rain/snow?
- KennyBlanken 3y agoWatch the video? He makes just such a thing.
- hcknwscommenter 3y agoHe makes something like that with acetone dissolved acrylic. It would be interesting to see what happens if you dispersed the microsphere material in a commercial paint. I think it would work?
- waysa 3y agoHe specifically engineered his particles to be as densely packed as possible. I assume the pigments in commercial paint would limit the cooling capacity. Probably that's why he went with a clear acrylic base (with bubbles to make it reflective).
- asimpletune 3y agoAs others mentioned the nighthawk guy has solved most of these problems, but what I do think he needs help with is improving the application. Currently his best method is just squeezing it out of a syringe. Best possible outcome would be something that can be sprayed and something that can be rolled on or applied with a paintbrush.
- itronitron 3y agoI thought it was odd that he got good coverage spraying with a hand sprayer bottle but then went through the effort of squeezing it out of a large syringe.
