Paint and Coating Tests




The Paint Testing and Coatings Research Laboratory is accredited to ISO 17025 and SAE AS 5505 for the testing and characterization of paint systems when performing Ahesion by Tape Test.

 

The tape test method is a quick identifier as to whether a coating has adhered to the substrate. The tape test can also be performed on coatings that have been immerssed in a fluid.

 

There are two methods described in the ASTM Specification;

 

Test Method A

  • An X-cut is made through the film with a carbide tip tool to the substrate.
  • Pressure-sensitive tape is applied over the cut.
  • Tape is smoothed into place by using a pencil eraser over the area of the incisions.
  • Tape is removed by pulling it off rapidly back over itself as close to an angle of 180º.
  • Adhesion is assessed on a 0 to 5 scale.

 

Test Method B*

  • A crosshatch pattern is made though the film to the substrate.
  • Detached flakes of coating are removed by brushing with a soft brush.
  • Pressure-sensitive tape is applied over the crosshatch cut.
  • Tape is smoothed into place by using a pencil eraser over the area of the incisions.
  • Tape is removed by pulling it off rapidly back over itself as close to an angle of 180º.
  • Adhesion is assessed on a 0 to 5 scale.

* Method B is not considered to be suitable for coatings thicker than 5 mils.
