AP Test Pen for Surface Tension (38 mN/m)

The AP Surface Tension Tester enables fast and reliable testing of the surface tension and surface energy of a wide variety of materials. It is ideal for checking whether surfaces are optimally prepared for bonding, printing processes, coatings, or further processing steps.

This practical test pen supports quality assurance and process optimization by allowing the wettability of plastics, coated materials, and treated surfaces to be evaluated quickly and easily.

Reliable Surface Testing

Whether in industrial manufacturing, workshops, laboratories, or at home – the surface tension tester delivers simple and reproducible results directly on the surface.

Your Benefits at a Glance

Typical Areas of Application

Ideal for plastics processing, bonding preparation, printing applications, coating control, quality assurance, and industrial manufacturing processes.

Application & Evaluation (38 mN/m)

This is how easy the test works:

1. Application: Draw a steady line on the surface to be tested using the test pen.

2. Observation: Wait exactly 2 seconds to see how the ink behaves.

Evaluation:

• The ink remains stable (continuous line): The surface tension is 38 mN/m or more. The surface is optimally wettable – ideal for secure further processing such as printing, bonding, or painting.

• The ink retracts (beading effect): The surface tension is below 38 mN/m. The wettability is insufficient, meaning inks or adhesives would not adhere optimally. The surface should be cleaned or pre-treated.
