Abstract
The present disclosure relates generally to two part adhesive compositions comprising a resin part including a curable resin selected from multifunctional, hydroxyl di-terminated polymer having alkene segments and epoxide segments in the polymer chain; an epoxy di-terminated block copolymer having siloxane moieties and bisphenol A moieties in the backbone and combination thereof and a hardener part including a curative for the curable resin. When mixed the compositions cure to a form that provides hardness but relatively low bond strength to a substrate and which can be removed from metal and other surfaces easily and simply with little residue.
