Welcome to SEMicro!
The same quality you have come to expect from the P.A.T.T.I.®
Our smallest and most portable tester yet - control module measures 3.5" x 4.5" x 1.5" and weighs just over 1 lb.
No conversion charts needed - simply set the piston and stub size prior to testing and the conversion is performed for you
The 2 line backlit alphanumeric display informs the user of the current piston and stub setting during each test
After the test, the display informs the user of the duration of the test and the average rate of pressure increase
Internal Memory slots can hold all related test data for up to 100 pull tests
The unit can be interfaced with a computer to display all testing data held in memory and basic software is included
Audible feedback helps to verify when buttons are pressed or when a test is complete
Units can be displayed in Imperial or Metric
User-adjustable power saving feature
Firmware is easily updatable via the USB port
Unit can be powered by 9 volt battery or via the USB port
Simplified design requires fewer internal parts and reduces the frequency of maintenance / repair
Can use the same pistons, pull-stubs and supplies as previous P.A.T.T.I.®
The self-aligning P.A.T.T.I.® MICRO quantitatively measures the adhesion strength of numerous coatings, including: paints, polymers, ceramics, inks, films, adhesives, and thermal or arc-sprayed metals.
Laboratory or field use.
The test surface can be smooth, rough, porous, flat or curved (please contact us for application specific solutions). Custom-machined pull-stubs are available at any size, either flat or with a radius to match curved surfaces.
The PATTI® can also be used to test the strength of adhesives under non-room environmental conditions from 32-212 degrees Fahrenheit (0-100 degrees Celsius).
The P.A.T.T.I.® uses compressed inert gas (CO2 cartridges for portability or bottled/shop air) to apply a continuous tensile load to an aluminum pull-stub which is bonded to the test surface with an adhesive.
After the adhesive has cured, the operator attaches the selected piston. After ensuring that the correct piston and stub size are set on the P.A.T.T.I. the operator pushes and holds the "RUN" button. A continuous load is then applied to the pull-stub until failure occurs, or until a specified load is reached.
Maximum load is displayed on a 2 line, backlit alpha-numeric display. When the test is complete, the display informs the user of the maximum tensile strength obtained during the test, the piston used, the pull-stub size, the total time duration of the test, and the average rate of pressure increase. All of this data can be saved to one of the 100 memory slots for future retrieval via the control module or your computer.
Here are some sample display images from an actual test that was saved to memory:
(3 Load Ranges)
The PATTI® instrument and method conforms to ASTM D-4541, "Pull-Off Strength of Coatings Using Portable Adhesion Testers". Using 20mm pull-stubs, the P.A.T.T.I. conforms to ISO 4624/16276-1.
Also can be used for the testing of coatings on concrete according to ACI 503-30 Appendix A, A.1 or ASTM D7234. 50mm pull-stubs required.
Asphalt testing can be performed using specialty stubs. Contact us for details.
