Question 1

How does PES-30 differ from a pure PDMS leveling agent in waterborne coatings?

Accepted Answer

The polyether modification makes PES-30 self-compatible with aqueous systems without pre-emulsification. It reduces dynamic surface tension faster than neat PDMS, suppressing crater formation and improving substrate wetting across both waterborne and solventborne platforms.

Question 2

What surface defects does PES-30 address?

Accepted Answer

PES-30 primarily targets cratering, orange peel, and poor flow in low-VOC waterborne coatings. The polyether-silicone backbone provides surface mobility that equalizes surface tension gradients responsible for Bénard cell defects.

Question 3

Is PES-30 compatible with UV-curable waterborne coatings?

Accepted Answer

Yes. PES-30 is non-reactive and compatible with most UV-waterborne acrylate dispersions. Recommended dosage in UV systems is 0.1–0.3%. Compatibility should be confirmed by draw-down testing since photoinitiator type and resin polarity affect final surface appearance.
