Abstract:
The present disclosure provides a multi-base material adaptivity pulling removal type binder product, a binder composition 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.
Abstract:
A stretch releasable adhesive tape is described including a backing and a first layer of a pressure-sensitive adhesive composition coated on at least one surface of said backing, the adhesive tape having a thickness between 0.05 and 0.10mm, and elongation at break between 850% and 2200%), being capable of being firmly bonded to a substrate and thereafter being removable therefrom after being stretched at an angle at 90°degree or greater degree from the surface of a substrate without rupturing prior to the removal of the tape from the substrate and without leaving substantial pressure-sensitive adhesive residue on the substrate, wherein the pressure sensitive adhesive contains a functional group terminated polyurethane. An electronic device comprising a stretch releasable adhesive tape of the invention is also described.
