Wetting Basics

- Main influencing factors

- Surface tension

- Substrate surface energy

Dynamic Wetting

- Related defects

- Craters, edge crawling,

de-wetting, Fish eyes,…

For fast application methods as printing or spraying high mobility towards

this interface is required for substrate wetting agents to be effective.

A good indication of the mobility and the effect of a substrate wetting

agent is given by the dynamic surface tension.

Test Method

Dynamic surface tension Bubble pressure tensiometer

Foam behavior

Product was stirred under high shear and density was determined.

Foam decay after 10 minutes was determined. Product with the highest

density has the lowest amount of foam.

Wetting & leveling Visual assessment. Ink applied on leneta card with wire bar.

Printability Ink was tested on Moser printing press in flexo mode at 100 m/min
