Testex Replica Tape
Model No. :
Brand : Defelsko
Testex Replica Tape is the universally recognized method for accurately measuring the peak-to-valley surface profile (roughness) of blast-cleaned steel and textured substrates. It consists of a layer of crushable microfoam affixed to an incompressible polyester backing that, when rubbed onto a surface, creates a precise, permanent, and physical mold of the roughness. This replica is then easily measured using a micrometer or a dedicated electronic reader to determine the height of the surface profile, a critical parameter for optimal coating adhesion.

FAQs
What is the purpose of measuring surface profile with replica tape?
Measuring surface profile is critical to ensure that the texture of a blast-cleaned substrate has sufficient height (roughness) for a coating to anchor properly, which is essential for maximizing coating adhesion and providing long-term corrosion protection.
How does work?
The tape has a crushable foam layer on an incompressible polyester backing. When rubbed onto a rough surface, the foam permanently deforms to capture a precise mold of the peak-to-valley profile. This compressed thickness is then measured by a micrometer.
How accurate is ?
Independent studies have validated the high accuracy and repeatability of the method. When using the High Accuracy Burnishing Tool and following the recommended procedure, the tape system typically provides an accuracy of
Are ?
All conventional tape grades (, , ) are now available in a newer, improved strip format that features easy-open/close packaging, though the legacy roll format may still be available via some suppliers.
What is the “High “?
This tool features a spring-loaded ball that ensures the replica tape is compressed using a consistent, perfect amount of force, regardless of the operator’s technique, thereby extending the range of the tape and significantly improving measurement accuracy.
What is the life of Testex tape after impression being taken?
Testex Replica Tape is intended to preserve a permanent record of surface profile readings. As long as the tape does not exceed 60°C and the impression foam is protected to avoid accidental compression, they should be able to continue to take accurate readings with the tape.
