Testex Tape is popularly called as Press-O-Film. Press-O-Film provides surface profile of a basted cleaned surface. It can produce virtually exact replicas of the blasted surface profile, which can be measured, using a snap gauge. Testex
tapes offers a simple and very accurate method of measuring blasted profiles
Testex Tape / Press O Film consists of layer of crushable plastic microfoam coated onto a
polyster film of highly uniform thickness.

Surface profile gauge or
testex tapes can test surface roughness. Most commonly used testex tapes
/ press o films are popular as it can give permanent record of the surfaces.
Place the Testex Tape (Press-O-Film) firmly on the blasted surface, apply moderate pressure with the burnishing tool, the replica has now been taken and can be measured using the snap gauge. Testing & Inspection can be done in three easy steps. Detailed procedure is furnished with testex kit or tapes.
Testex Tape is supplied in a roll containing 50 tests and is available in four different grades to cater for different applications. The snap gauge is supplied in a carrying case with a burnishing tool.
Paint applicators, inspectors and researchers for its simple operations and results prefers to use Testex tapes (Press-O-Film)
Testex Tape (Press-o-film) complies with ASTM, NACE and SSPC methods measurement.
ASTM- Reproducibility is given in ASTM Standard 4417-93 for both “X-coarse” and “coarse” grade replica tape.
NACE- Standard RP0287-95 addresses the issue of accuracy of measurement, test results.
SSPC- The Society for Protective Coatings, recommends a minimum of three measurements of profile per 100 square feet (10 square meters).
ISO- International Organization for Standards- Draft Standard ISO8503-5 describes preparation of steel substrates before application of paint and related products.
Testex kit comprises two rolls Press-O-Film (X Coarse supplied as standard, specify different grade if required), snap gauge and burnishing tool. |
