Need a food safe encapsulant to coat a small electronic device.
Need a food safe encapsulant to coat a small electronic device.
(OP)
I need to coat or mold a small (2cm x 3cm x 0.5cm) electronics device (chips and coin cell battery) that will be placed into a drinking bottle. The liquids will be normal drinks (no alcohol). Does anyone have an idea for a particular product or a resource to find one?
Thanks,
DJ

"Food safe" is a pretty generic term. It depends on how long the part you are introducing is in contact with the food, what materials can leach out of what you are introducing, whether it supports bacterial growth (either as a nutrient or a safe harbor for bugs), how cleanable/sterilizable it is. There are a plethora of regulations surrounding the subject, suggest you look at http://www.nsf.org/

The device has to go inside the bottle. There will be design considerations to prevent choking. I'll check out the NSF site.
My leading candidate is platinum cure PDMS. My concern is tearing from the inside. I may also consider coating certain spots to smooth them. Parylene is interesting as well however I believe is usually deposited as a very thin coating and it doesn't work well with other encapsulates.
The perfect material would be a low temp epoxy. I've been told a suitable epoxy doesn't exist.
