Water Based Acrylic Pressure Sensitive Adhesive for Making Surface Protective Film

Acrylic pressure-sensitive adhesive composition for a protective film, and more particularly, by adjusting the elastic modulus of the acrylic pressure-sensitive adhesive using an acrylic copolymer having a specific glass transition temperature and a terpene phenol-based tackifier, It relates to an adhesive composition that optimizes and prevents occurrence of seasonal residue phenomenon.

The acrylic pressure-sensitive adhesive composition according to the present invention is easy to peel off from the attached surface by optimizing the peeling force when removing the protective film, there is no lifting phenomenon even when stored at high temperature and low temperature for a long time to minimize the problem that the foreign matter inflow or other protective film may have Excellent effect.

Pressure-sensitive adhesive, acrylic copolymer, glass transition temperature, terpene phenol-based tackifier, softening point, peeling force, residue problem.
