Abstract

Disclosed herein are adhesive compositions comprising (a) a first component; (b) a second component that chemically reacts with said first component; and (c) graphenic carbon particles having a compressed density of 0.9 or less. Disclosed herein are associated methods for forming the adhesive compositions and applying the adhesive compositions to a substrate to form a bonded substrate.
