Completely removable pressure-sensitive adhesives by polyurethanes molecular-weight and HDI/HDI trimer ratio |
| 초록 |
Polyurethane pressure-sensitive adhesive with high durability and removability was successfully synthesized by controlling the molecular weight of the polyol and the composition of the crosslinking agent. Crosslinking reaction was optimized by controlling hexamethylene diisocyanate and additive content. It was possible to control adhesion by increasing the molecular weight of polyethylene glycol to reduce adhesion or to increase adhesion by reducing the molecular weight. One hundred eighty-degree peel tests by universal testing machine were used to evaluate mechanical peel. The peeled interface was observed by atomic force microscope and scanning electron microscope. It provides an effect that can be used by adjusting the adhesive force according to the type and use of various adherends. It was proved that the adhesive utilizing the wettability of urethane can have various adhesive strengths without transcriptional area. |
