UV: American Ultraviolet Cool Cure UV Exposure Chamber
The American Ultraviolet Cool Cure Chamber allows the user to cure UV-curing polymers, adhesives, optical cements, photoresists, epoxies, etc., without heating up the substrate or exposing the substrate to infrared or visible light. This helps the polymer to cure without heat-induced distortions. The temperature within the chamber typically stays lower than 35C for long exposures. By programming repetitions of a timed on/off cycle, the temperature can be maintained at very close to room temperature. It is very safe to work with, because the UV lamps are interlocked to the chamber door. No special personal protective equipment other than clean gloves are required while using this machine.
The machine has four high intensity 365nm LED light sources located in the ceiling of the chamber. There is no infrared or visible white light spectrum from these lamps, like you would get from a mercury vapor lamp. And there are none of the usual risks associated with mercury vapor lamps (explosion, exposure to mercury, high voltage arcing, ruined optics, or high temperatures).
All internal surfaces are mirrored to help uniformly expose anything put in the chamber. Any UV-curable material optimized for 365 to 405nm will be exposed if the exposure time is sufficient.
The machine has three modes of operation:
- On/Off Cycle
- For a cycle of 1, this serves as a simple one-shot timed exposure.
- Multiple cycles allow longer exposures while keeping heat to a minimum.
- Press “Go” button or tap foot switch to start timed process.
- Continuous Mode
- Hit “go” or tap foot switch to turn lamps on, hit “go” or tap footswitch to turn lamps off.
- Manual Mode
- Press and hold “go” (or press and hold footswitch) to turn on lamps, release “go” button (or release footswitch) to turn lamps off.
Always wear CLEAN gloves, when touching the touchpad controls of this machine, or they could be destroyed. Please only touch the interior or exterior of this machine with CLEAN gloves. Do not touch with wet, sticky gloves.
Always enable “UV Exposure Tool” on Badger when using this tool.
