The present disclosure provides a multi-base material adaptivity pulling removal type binder product, a binder position and an assembly. The binder product contains an acrylic acid copolymer, a flexibilizer, tackifying resin and an isocyanate curing agent. The binder product comprises a binder layer formed by curing at least a part of the binder composition. The assembly is formed by bonding the binder layer. The binder can be used for firmly bonding various base materials, comprising both high surface energy base materials and low surface energy base materials; meanwhile, the binder can be pulled and removed from the base materials at a large angle. The binder is particularly suitable for the fields of smartphones, tablet computers and a newly developing electronic market.

A rosin dispersion is a reaction product of, by dry weight based on total dry weight of the rosin dispersion, from 80% to 98% a rosin resin, and from 2% to 20% a dispersant. The rosin resin is processed by at least one method of a) modification, b) hydrogenation or disproportionation, and c) polymerization or esterification from raw material rosins. The dispersant is selected from C.sub.18-C.sub.32 aliphatic carboxylic acids, olefin (meth) acrylic acid copolymers, and other acid/anhydride modified polymers. A continuous process for preparing the rosin dispersion and an adhesive formulation comprising the rosin dispersion are also included.
