Pressure sensitive adhesives (PSA) are commonly used from daily life to industry. Coupled with increasing environmental issues, there are tremendous demands for environment-friendly PSA development. In this presentation, a non-volatile and non-toxic eutectic liquid (EL) was developed as a substitute of both volatile organic diluent and toxic tackifier, which are conventional components of PSA. Substituting the EL for diluent and tackifier not only eliminates many disadvantages of conventional PSA such as use of toxic and volatile components but also simplifies the manufacturing process by excluding solution casting and solvent recovery steps. By using poly(styrene-butadiene-styrene) block copolymer as base matrix, the EL significantly enhanced adhesive properties, yielding adhesives especially suitable for conditions under high shear. |
