Pressure Sensitive

A term commonly used to designate a distinct category of adhesive tapes and adhesives which in dry form (solvent/water free) are aggressively and permanently tacky at room temperature and that firmly adhere to a variety of dissimilar surfaces upon mere contact, without the need of more than finger or hand pressure.

Release Liner (aka Slip Sheet or Interliner)

A web of sheet material used as a protective liner, which covers the adhesive side of the tape.  It is removed prior to application.  Most frequently found on double-sided tapes and label stocks.

Subsequent Adhesion

The force required to remove a unit width of pressure sensitive tape from a standard panel after it has been in contact with a release liner for a given period of time.   This must be compared with the adhesion of the same tape that has  not been in contact with the release liner to determine the degree of loss of adhesion.

Surface Energy (Surface Wetting Ability)

The measure of surface tension in dynes.  The lower the surface energy of a substrate, the more difficult it becomes for an adhesive or coating to wet out that surface.

Tack

The property of a pressure sensitive adhesive that allows it to adhere to a surface under very slight pressure.   It is determined by the ability of the adhesive to wet quickly the surface it contacts.
