Question 1

How does PW-500 prevent hard settling in solventborne primers?

Accepted Answer

PW-500 micronized PE wax builds a weak thixotropic gel network in the continuous phase at rest, suspending dense pigments and fillers. Under application shear the network breaks down reversibly, restoring normal spray or brush viscosity without affecting final film gloss or adhesion.

Question 2

What is the recommended addition level and dispersion method for PW-500?

Accepted Answer

Typical dosage is 0.5–2.0% on total formulation weight. For best results, add PW-500 as a dry powder to the mill base alongside grinding media. Alternatively, pre-disperse in warm solvent (50–60°C) before let-down. Avoid high-speed dissolution that destroys the wax particle structure.

Question 3

Can PW-500 be used in waterborne or high-solid coatings?

Accepted Answer

PW-500 is optimized for conventional solventborne and high-solid alkyd or epoxy systems. In waterborne coatings, an aqueous PE wax dispersion or emulsion grade is preferred, as undispersed powder tends to agglomerate in aqueous environments and provides inconsistent anti-settling performance.
