Terentateks have a limited blanket Force resistance. Rave invented and patented a method of alchemizing the hide to preserve and enhance that property. It still doesn't give Force immunity, mainly because it's cool for the stuff to block fancy schmancy complex stuff, but no coat in the verse is going to keep you from getting chucked through a wall by a Sith Lord. Make it harder to crush? Sure, whatever. It all gets negotiated in PVP anyway.
