Does anyone know what Apple is coating the aluminum on the back of its iPhone 5 and 5s devices with? The metal appears to be anodized (and they've said as much) but the coefficient of friction between 2 iPhones is about .14. They use an omniphobic coating on the front glass which makes sense...
@IFRs
Hard anodizing is an interesting idea. We gave it a thought early on but rejected it because of color constraints and I didn't think it would have the lubricity. Have you had any experience with it?
Thank you ornerynorsk and IRstuff. I'll look into ceramics. I cook a lot myself but I'm not familiar with ceramic coated cookware. Are these ceramics comparable to Teflon®? Any idea who's coating it?
We are looking for an omniphobic, nonstick, low coefficient of friction coating for a kitchen device used for hand grinding relatively soft foods like herbs and spices. PTFE was our first choice but because this is being sold to the 'health conscious' market, it was eliminated as an option. (I...
