“…Since the introduction of pressure-sensitive acrylic adhesives over half a century ago, they have been successfully applied in many fields of industry. PSAs are used in self-adhesive tapes [2][3][4][5][6][7][8][9][10], labels [11][12][13][14][15][16][17], signs and markings, protective films [12,14,15], assembly operations [4,11,12,[18][19][20][21][22], as well as in dermal dosage systems for pharmaceutical applications [2,6,7,[10][11][12]17,[23][24][25][26][27] and biomedical electrodes [28]. Over the last 60 years or so, the development of acrylic pressure-sensitive adhesives has made tremendous progress, so much so that both manufacturers of pressure-sensitive adhesive articles and their adhesive suppliers now use sophisticated equipment and precise methods to study pressure-sensitive adhesive performance: tack, adhesion and cohesion.…”
