Project S.T.A.T: Scotch Tape, Adhesion, and Temperature

Overview

Objectives/Goals My goal from this project is to determine if there are differences between 3M tapes and to understand the affect of temperature on adhesives. The purpose for undertaking this study is to prove a tip from my mother for removing adhesives using heat and for pure curiosity. Methods/Materials To execute my objectives and goals, I made two procedures. One tested difference of tape types, by letting 3cm x 2cm tape strips from each sort hang from a certain height with a 300 gram weight attached and timing the duration held. A second set of directions uses a blowdryer and icepacks to influence heat on adhesives. Materials, specifically, are as follows: a 300 gram weight; Satin, Magic, and Transparent Tape; a thermometer; a watch; icepacks; and a blowdryer. Results Satin tape held longer than both Magic and Transparent tape. Magic tape was considerably stronger than Transparent, placing it second in length time and Transparent third. Furthermore, heat shortens the time an adhesive can hold dramatically, cold slightly, but room temperature leaves things hanging the longest. Conclusions/Discussion After completing my project and analyzing the results, I have concluded that heat concentration decreases the time held; the more heat the less time. Also, cold has the same affect; the colder from room temperature, the lower the duration. Finally, there is inequality among tapes; Satin holds best, then Magic Tape, and the weakest tape is the Transparent type.
