Pigment volume concentration
(PVC) has significant effects on the properties of coatings, (3) including a great effect on the transport of corrosive species of electrolytes through them.
Rohm and Haas Company has been granted a patent for a fluid extender pigment mixture, comprising at least one extender pigment; at least one thickener; and optionally at least one binder wherein the extender pigment has an average particle size of less than three [micro]m and an average oil adsorption value as measured by ASTM D281-31 of less than 30; wherein the mixture has a pigment volume concentration
of at least 80, a volume solids of no greater than 50, a specific gravity of less than 3 g/cc and a viscosity at a frequency of 1.25 sec-1 of at least 10,000 cps.
Pigments in paints are often qualified by the terms: Oil Absorption, Pigment Volume Concentration
(PVC), or Pigment to Binder Ratio (P:B)

Acronal Optive 410 shows excellent tannin stain blocking properties without adding reactive pigments and can be formulated in a higher than typical pigment volume concentration
(PVC) range, up to 45%, while still maintaining performance properties, according to the company.
The coating had a 60[degrees] gloss at 20, and a pigment volume concentration
Considerations of pigment volume concentration
(PVC) effects and the critical PVC (CPVC)
Coating C1 contained [TiO.sub.2] only at 15 PVC, while Coating C2, in addition to a similar level of [TiO.sub.2], also contained a barium sulfate extender, which increased the total pigment volume concentration
