Coated metallic sample peel test

  • US Patent No. 8820155
  • Issued: September 02, 2014
  • Status: Active

A method for conducting a peel test of a polymer coated metallic sample includes making a peel test specimen having a polymer joined to a substrate. A free portion of the polymer is left unattached to the substrate. The peel test specimen is positioned in an environment for testing in such a manner that the polymer is allowed to peel downward from the substrate. A weight is joined to the free portion of the polymer and a start time is recorded. The attached portion of the polymer is periodically measured and the elapsed time is recorded. A peel rate is calculated from the measurement and time.
