WHY WHITE LEAD HELPS PAINT " W O R K " EASILY
You've noticed how paints
with a high lead content
flow readily . . . level off
smoothly . . . pass all tests
for ease of brushing with
flying colors.

The reason is this: Basic carbonate white lead and
oil have a strong attraction for each other. A reaction
takes place between the vehicle and the surface of the
pigment particles. This reaction --commonly known as
the formation of lead soaps --facilitates flow, promotes
brushability.
Improvement in working qualities is but one of the many desirable properties white lead imparts to paint. Others are better adhesion, more thorough drying--plus proved durability."
Check over the five basic carbonate white leads the Dutch Boy offers. They range from a low oil absorption type to one with extra-high hiding and paint thickening power. Among them you will find a lead exactly suited to your needs.
