Abstract
The present disclosure provides a multi-base material adaptivity pulling removal type binder product, a binder compositon 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.
