Question 1

How does PU-600 differ from conventional urea-based anti-sagging additives?

Accepted Answer

PU-600 uses a polyurea backbone that forms denser hydrogen-bonding networks compared to monourea types, delivering sharper thixotropy recovery and effective anti-sag performance in high-build industrial and protective coatings at lower dosage levels.

Question 2

Is PU-600 compatible with waterborne systems?

Accepted Answer

PU-600 is designed for solvent-borne and high-solids formulations. For waterborne systems, a hydrophilically modified polyurea dispersion or an HASE/HEUR rheology modifier is the appropriate alternative.

Question 3

What is the recommended incorporation method for PU-600?

Accepted Answer

Add PU-600 during the grinding or let-down stage under medium shear (500–1000 rpm). Pre-heating the additive to 40–50°C before addition improves dispersion homogeneity, especially in high-viscosity alkyd or epoxy binders.
