    The Polyken probe tack tester is a portable device for measuring the tackiness of pressure-sensitive adhesives and cements. The tester provides a means of bringing the tip of a probe into contact with the adhesive at controlled rates, contact times, and temperatures, and subsequently breaking the adhesive bond thus formed, also at controlled rates. The maximum force during the break is taken as the measure of tackiness.

    Data are presented to illustrate the utility of this instrument on commercial pressure-sensitive adhesive tapes. Tack values for all tapes increase with increasing pressure, with increasing time of contact, and with increasing rate of separation. Tack values decrease with increasing temperature. Tack value is shown to be independent of the thickness of the adhesive. Reasons for the above are discussed and the reproducibility and statistical parameters of the test are provided.
