Description

<p>The properties of a novel pressure sensitive adhesive (PSA) based on tackifier (TF) surface segregation were compared with the general PSAs with or without conventional TF. The peel strengths of the general PSAs were relatively high at room temperature, but decreased drastically under high temperatures, such as 85℃. On the other hand, the PSA based on TF surface segregation maintained high peel strength to Polyolefin or ABS under high temperatures. The PSA based on TF surface segregation is suitable for laminating decorative films to automobile parts that require heat resistance.</p>
