Testex Tape / Press-O-Film USA

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 of surface.

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.

Shot And Grit-blasting Comparators

These two comparators are specially designed to check the roughness of steel surfaces which have been blast cleaned to cleanliness grades sa 2. 5 and sa 3 before painting. They conform to iso 850.
