ReliaPull ADHESION TESTER View larger


New product

The ReliaPull® ADEHESION TESTER (now patented!) was built to help reduce the human variation imposed on the results of Tape Tests performed manually. This equipment mechanizes the test. Tape tests are performed in many industries requiring a quick check on the adhesion of inks, paints or coatings to a surface.
There are multiple standards written to describe consistent ways to perform the tape test, however, experience has proven it is very difficult for one operator to perform the test the same way each time, much less for multiple operators to duplicate the method.

By using the ReliaPull® ADHESION TESTER to perform your tape tests, it doesn’t matter who pulls the lever the method is repeated exactly the same way each time. The ReliaPull® ADHESION TESTER performs the Tape Test for adhesion referred to in the ASTM standards D3359 and F1842. You may pre-condition / cross-cut samples using the current procedures and the standard method for evaluating the results.

The ReliaPull® provides a method for consistently applying and consistently removing the tape.

ReliaPull® gives you results you can rely on.
Step 1:
Wind any tape you would normally use to conduct a tape test, for example 600, 610, 810…, through the equipment as shown. Any tape on a 3” core that is between 1/4” and 1” wide will work.

Step 2:
To begin a test, tip the equipment up-right, grab the handle attached to the application brush and pull up to dispense a length of fresh tape for each test. Typical standards suggest approximately 3”, however, we’ve found it beneficial to use 7" or more to see patterns of adhesion.

Problems with Current Methods:
Tape on typical dispensers has area that is exposed to drying or debris. When done by hand, oils from fingers or other debris can get on the adhesive. Tape easily tangles.

Step 3:
Place the equipment on the area of the substrate to be tested. Return the brush to its home position. Note, the brush counter-rotates across the tape with consistent pressure and application motion, therefore this operation can be repeated by any operator.

Problems with Current Methods:
Bubbles or missed areas occur. Different application pressures, methods or patterns cause different bonds between the tape and the substrate. This is very difficult to repeat by hand or from one operator to another.

Step 4:
Activate removal. When the tape removal is activated a roller is lowered to ensure the tape is removed at 180
degrees from the angle of application. Again, a repeatable action. Problems with Current Methods: It is nearly impossible for tape to be pulled at the same angle and rate by each operator, each time, by hand. Final results depend on how the operator performs each test.

Step 5:
Review results. A viewing area is provided in the front of the equipment. Use the same criteria you normally see or reference the appropriate standard. You have the option of removing the section of tape just used for
testing to keep with your records/retains.

Alternatively, you may record the date/job number on the tape and tore on the spool as a record of performing the tests. You may also dispose of the tape neatly as the spool becomes full. Problems with Current Methods: Tape curls, tangles and sticks to fingers. Wads of tape end up strewn across work area. Tape must then be attached to the sample or another record.


One of the
most important and widely-used standards in the paints and coatings

industry, has just been updated and improved.  ASTM D3359-09 Test
Methods for Measuring by Tape Test
covers procedures for assessing
the adhesion of coating films to metallic substrates by applying and
removing pressure-sensitive tape over cuts made in the film.

ASTM D3359

Test Methods for Measuring by Tape Test

now references a suitable mechanical device that is helpful in maintaining
consistent pressure on the tape during application, thereby helping users
get more accurate results.
