Automatic Pull-Off Tester: Coating Adhesion Test

Automatic Pull-Off Tester: Coating Adhesion Test

Click here to listen to a brief summary of the article.

In the world of paints and coatings, achieving a strong bond with the underlying surface is crucial for ensuring long-term performance. This article introduces the SADPO500/A, a portable digital pull-off device with automated features, set to revolutionize the way we assess adhesion.

This instrument gauges a coating’s pull-off strength by measuring the tensile force it can withstand before detaching.

Instruments for evaluating coating adhesion

Numerous tools are available for assessing the adhesion of coatings. Here are a few examples:

Multifunctional Digital Coating Thickness Gauges:

Coating thickness gauges are employed to non-destructively measure the thickness of coatings on metallic substrates. They are ideal for quality control across various industries, including automotive, marine, and construction. These instruments can measure both insulating and non-ferromagnetic coatings.

Cross Hatch Tester

This SADT502 tool is used to evaluate the adhesion of various types of coatings through destructive testing but limited to a very small surface area. It utilizes a metal head with blades set at specific distances to measure the adhesion of coatings with different thicknesses. This tool is commonly employed alongside coating thickness gauges, hardness testers, glossmeters, and colour difference meters.

This tool, also known as Pull-off, measures the force required to pull a metal disk which is attached to coating materials using hydraulic pressure. Both the manual and the new automatic models are available.

These tools are easy to use, accurate, versatile and durable.

Features include a speed dial, data storage with date and time, and pressure display in various units.

The device is weatherproof and equipped with a built-in rechargeable lithium battery.

In the following videos, we will see two pull-off models.


Let’s begin with the video featuring the manual model.



Now, let’s move on to the automatic model, showcasing the innovations that make the process smoother.
