WHICH MODEL IS BEST SUITED FOR YOUR USE?
Our Activities
DFD® INSTRUMENTS develop, design and manufacture the PAT adhesion testers, which are high precision pull-off type measuring instruments for adhesion and bond strength testing of all types of films, coatings, laminates, adhesives, metals and other materials. The adhesion testing technology, based on the concept Dynamic Force Distribution™, ensures completely reproducible test results regardless of the testing circumstances like e.g. the shape of the substrate. Also, with this test equipment laboratory results are always comparable with field test results. The unique design of PAT ensures total test reliability: The test results are not operator-dependent. The testing machines are supplied with attachments ranging from the 1 kN micro-adhesion tester (typically for testing on very small components or areas) up to the fully automatic 80kN tester (mainly used for metal coatings). The equipment is either manually operated or fully automatic. Logging and storing of the test results can be done with the Windows-based digital testing module.
Digital Adhesion Testing
The latest version of the digital adhesion testing module has been released.
The stress increase rate can
now be now controlled automatically by the computer and can be set to comply with the relevant
adhesion testing standard.

Testing in accordance with ASTM-C633
Many companies insist that the adhesion testing of thermally sprayed coatings is done according to ASTM-C633. What is this, and can it be done with the PAT test equipment? The PAT equipment is designed for ASTM testing,
and the fact is that it is actually much simpler to do this testing with PAT than with
large, stationary conventional tensile testing equipment.

Palm-Held Pull-Off
Adhesion Tester
the size of a three
inch thick A4 sheet of paper, weighing 1.9 kg, so there is no excuse for not
bringing it even to the most remote testing site!

PATTM Versatility
The PAT adhesion test equipment solves the problem of incorrect measurements by
distributing its pull stress 100% evenly over the test area. The PAT range meets
all your testing requirements:
Hydraulic pulling action
Field and lab testing - portable design
The test method complies with ISO 4624, ASTM D4541, EN 1542, ASTM C633, to mention
the most relevant standards.
Complete range of interchangeable pulling heads ( from 1kN up to 80kN) and test
elements (dollies) ranging from Ø2.8mm to Ø70mm.
With a choice of manual, automatic, analogue and digital models,
PAT is used worldwide for adhesion testing of all types of paints and coatings including:
