Question 1

What viscosity grade should I select for a brush-applied waterborne stain?

Accepted Answer

LV-60 at 600 mPa·s (2%) is ideal for thin-film stains and basecoats where extended open time and smooth leveling are priorities. For higher-build architectural paints requiring stronger sag resistance, a medium-viscosity HEC in the 3,000–6,000 mPa·s range is more appropriate.

Question 2

How does LV-60 affect open time compared to HPMC in waterborne formulations?

Accepted Answer

HEC grades like LV-60 generally provide longer open time than HPMC at equivalent viscosity because HEC does not exhibit the thermal gelation behavior of HPMC. This makes LV-60 preferable in brush-application systems where wet-edge extension is critical.

Question 3

What is the recommended addition sequence for LV-60 in a waterborne paint grind?

Accepted Answer

Pre-disperse LV-60 in water under moderate shear before adding pigments or extenders. Avoid adding dry powder to a system already containing pigment slurry, as this promotes fish-eye formation. Typical loading is 0.2–0.5% on total formulation weight.
