(OP)
Something similar to what these guys are selling in a sticker form: https://egrips.com/

I measured (roughly) the static friction coefficient between their material and a smooth piece of plastic; it's just below 2 and a little over 2 with finger skin. It is not tacky at all.

The ultimate goal is to produce a PC or TPU cell phone case "coated" with this material.
