MATERIALS TESTING
 
Automatic adhesion tester for testing with very small specimens and with very low pull force
 

PAT micro and nano adhesion testing.  High precision tensile and shear testing of bond strength, testing of thin films, thermal, plasma, HVOF, CVD, PVF sprayed coatings.

 

PAT MICRO adhesion testing is designed for testing in confined areas, particularly on small components of irregular and awkward shapes.  DFD technology: thin film tensile strength test equipment for adhesion testing.
Testing coatings and bond strength on fragile or thin substrates and components where the overall pull force must be strictly limited. The PAT range of film adhesion testing equipment from DFD Instruments

Description 

Portable and simple to use. 
Produces comparable test results both in the laboratory and on site.
Precision gauge with both MPa (N/mm2) and p.s.i. reading.
Simple layout of control panel.
Rate of tensile force increase is infinitely variable between zero MPa/sec (standstill) up to maximum rate (the rate depends on the size test element used).
110/230V mains power.  Battery power is an optional extra.
All AT101 adhesion testing machine models can have the data logging module built in when new or retro-fitted into existing units.
Testing of coatings on any shaped substrates, e.g. inside and outside pipe surfaces. 
Supplied in solid aluminium case.
