PAINTS
Zinc Oxide in organic coatings provides a broad spectrum of
properties: optical, chemical, biochemical and physical. Over
the past century the paint industry, in its constant
development of improved products, has utilized various aspects
of those properties to high degree.
Manufacturers discovered that they could produce coatings of
brushing consistency and good suspension properties by
incorporation of Zinc Oxide into their pastes. Painters noted
that they furnished better hiding power, whiteness, cleaner
tints, tint retention, and durability as well as nondarkening
in the presence of sulfur fumes. French-process Zinc Oxide has
been proved superior to American-process type in fungus
resistance and less sulfide staining.
