Surface Tension Test Pen - Value Options

Check the wetting behaviour of a material surface before a coating, printing or adhesion process.

Check surface treatment with a visible ink test

✅ See how the test ink behaves - Draw a line and observe whether it remains continuous or forms beads.

✅ Compare different test values - Separate pen options let you select the nominal surface-tension level required for the check.

Use the test value and acceptance criteria appropriate to the material and process. This is an assessment aid rather than a guarantee of adhesion.

Keep the pen tightly capped when not in use.
