Keeping Resin Warm with a ThermalVatBand
But don’t worry, there are a few options to keep your resin warm:
- A chamber heater / PTC heater can heat the entire resin box.
- A fermentation belt, like the ones used for mead or kombucha, can heat the exterior vat.
- A ThermalVatBand is a direct-contact thermal tape with a regulator.
All of these options will get you to your goal, but each has its pros and cons. For example:
- A PTC heater heats the entire box, including the resin, which might not be ideal.
- A fermentation belt needs a thermal control system, unless you’re okay with the default temperature setting.
I chose the ThermalVatBand and installed it on the interior of my vat for fast thermal transfer. However, the creator of the TVB doesn’t recommend interior installation because it can be tricky. Resin is a slippery and invasive substance, so it’s important to get a good seal on the flash tape. In my first attempt, I had some trouble, but for my second install, I used wider flash tape and wrapped it under the vat before the fep tray goes in. This way, the longest runs of tape aren’t in the resin, which reduces the risk of a breach. After three months, I haven’t had any issues yet.
All in all, I’d definitely buy the ThermalVatBand again. It might be a bit more expensive than DIYing it, but it’s worth it to have everything in one package and a creator/owner to reach out to if you need help. Of course, your experience might be different, but for me, it was totally worth it.
(note this is just my opinion, I bought a TVB on my own)
