Replica tape for measuring blasted surface profiles. By placing the Tqc replica tape on the surface and rubbing over it, the Rt (total roughness) or peak-to-valley height of the profile can be taken and then measured with a film thickness meter.

1. TQC Replica tape consists of a layer of compressible foam affixed to an incompressible polyester substrate.
2.When pressed against a roughened/gritblasted (steel) surface, the foam collapses acquiring an impression of the surface.
