Brought to you by TQC Sheen, our paint testing specialist brand, our robust and reliable pull off adhesion testers comply with a number of international standards.
The PosiTest range of pull off adhesion testers swiftly and accurately measure the force required to pull a specified test diameter of coating away from a substrate using hydraulic pressure.
We make manual and automatic adhesion testers and both models feature powerful hydraulic pumps. You get an electronically controlled pump on the automatic version and both options apply smooth and continuous pull off adhesion tester pressure. This reduces user effort and eliminates any risk of operator influence over the pulling process.
Every PosiTest adhesion tester pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cell. Plus the high-grade industrial pressure sensor ensures continued accuracy.
Our PosiTest pull off adhesion testers come in an environmentally sealed enclosure that’s weatherproof, dustproof and shockproof.
Our adhesion testers don’t need an external power source. This makes them fully portable and perfect for use both at the lab or out in the field.
The PosiTest adhesion tester compensates for misalignment. The self-aligning, quick-coupling actuator and spherical articulating dolly head enable uniform distribution of the pulling force over the surface under test. This prevents a one-sided pull-off and you get reliable, accurate measurements on both smooth or uneven surfaces.
The internal memories of our automatic adhesion testers are powerful enough to store data and user notes on up to 1000,000 pulls across 1,000 batches. The wealth of information it can hold includes:
The internal memory of the manual version of our adhesion tester can store information for up to 200 pulls, including:
You’re in control of your adhesion tester’s pull rate: the pull rate indicator allows you to monitor and adjust the rate of pull in accordance with international standards.
Our PosiTest adhesion testers are relied upon by teams operating across multiple sectors – everything from food and beverage manufacturers through to marine, defense, power and construction and engineering companies.
You can rely on our pull off adhesion testers to give you highly accurate results to the most stringent of international standards, including:
Across the IP portfolio we make a wide range of adhesion tester devices and products. For example, our customers have been equally impressed with the TQC Sheen Pull Off Adhesion Tester Model Pat GM01 GM04 and have found that their adhesion tests are more accurate using our TQC Sheen Cross Cut Adhesion Test KIT CC1000.
We’ve learnt a thing or two about how to build exceptional adhesion testers over the years. And we like to share this knowledge when we can. Why not check out our complete guide to pull off adhesion testing here? If you have found yourself in a sticky testing conundrum, or simply have more questions – just get in touch!
You can choose a number of optional extras to support the inspections you do with your PosiTest pull off adhesion tester device.
Drilling template and drill bits to isolate the test area. Ideal for thicker coats on concrete.
Our powerful software analyzes your test results and allows you to view them clearly in graph, chart or histogram format. Plus you can export your adhesion tester data to a document or spreadsheet for convenience.
Get additional adhesive, mixing sticks, palettes and cotton swabs for your adhesion tester.
Additional supplies of 10, 14, 20 and 50mm dollies for your Positest inspection device are available.
So, how do you use a PosiTest pull off adhesion tester? It’s a simple enough process, just follow these basic steps. You’ll soon be performing highly accurate PosiTest inspections of your inks and coatings:
