Polyken tack test

Procedure for Polyken Tack Test (ASTM D2979-71). A 1-inch square of substrate coated with adhesive was adhered to the top of the brass cylinder. The cylinder was inverted, rubbed on the bench top, and placed right side up on the Polyken Tack Probe Tester. The probe speed was sent at 1 cm/sec and 1-sec dwell time. A 20-gram weight was used. Both the stainless steel probe and the brass cylinder were cleaned with toluene before each use, and sufficient time was allowed for drying. The force required to overcome the bond to the probe was recorded in g/cm. Seven trials were made and an average reported.

Several variations of the test exist. Historically, the first referenced probe test is the Polyken probe tack test developed by Hammond [6]. In this case, the probe has a flat tip and is upside down. The compressive force is controlled by lifting a...

Influence of type and amount of clay added on the tack of adhesives. The probe test (Polyken test) was used. The device measures the force required to separate a stainless-steel probe (0.5 cm diameter) from the adhesive under low pressure and at short contact times. Tack was tested with a 100gcm contact pressure, 1 s dwell time and at a 1 cms test rate.
