FINAT 2 Assisted Pull-Peel Table, 90-degree, QC-20 Fitting
The FINAT 2 Assisted Pull-Peel table (90° Peel Test) is fitted to the anvil plate of a motorized test stand and then connected to the crosshead of a test stand. It is commonly used for conducting peel tests on adhesive tapes and films.
The carriage of the peeling table is directly driven horizontally by the vertical movement of the test stand crosshead. This maintains a constant peel angle of 90 degrees.
The carriage is equipped with adjustable rails into which float-glass can be inserted. Float-glass is used as a standardized surface onto which the specimen adheres. Float-glass to be ordered separately (part numbers PSV15030 and PSV15031).
Fitted with an adaptor having QC-20mm female hole
Typically gives lower values than FINAT 1 and is considered useful when the failure mode of materials is ‘paper tear’
- Remove backing material from 25 mm wide strip
- Affix strip to float glass (PSV15030) and roll twice using a standard roller (PSV14155)
- Fit float glass into a horizontal pull-peel table (PDV15031) positioned on the base of the tensile tester
- Fit strip into the upper grip (Mec227-BG50) of the tensile tester. The test angle is now maintained at 90 degrees
- Separate the adhesive strip from the test plate at a rate of 300 mm/min
- Record data from the central section of the adhesive strip as it is peeled
- Calculate the average of the peel force and express the value as Newton/25 mm width
- Describe the type of failure (cohesive failure, adhesive transfer, paper tear, etc.)
