pressure sensitive adhesive

Pressure Sensitive Adhesive (PSA) is a term often used to refer to a specific category of adhesive tapes and adhesives. These adhesives are very tacky at room temperature in dry form and adhere reliably to a wide variety of surfaces applied just with finger or hand. They do not require water or solvent activation and provide good adhesion to paper, plastics, glass, wood, cement and metals. They have fairly good cohesion and elasticity. Despite their aggressive stickiness, they can be touched with fingers and removed from smooth surfaces without leaving any marks.
