ABSTRACT
Pressure-sensitive adhesives (PSAs) are polymeric materials that can form a physical bond with another material upon brief contact and with light pressure. Examples of applications of PSAs include offi ce, price marking, and electronic data processing labels, as well as offi ce, packaging, diaper, auto/masking tapes, bandages, decals, etc. Th e general technical requirements for these types of materials are tack, peel resistance, and shear resistance. A wide range of PSA products have been designed based on the balance of these properties (see Applications of Pressure-Sensitive Products, Chapter 4).
