Critical Pigment Volume Concentration CPVC

Pigment Volume Concentration (PVC) and Critical Pigment Volume Concentration (CPVC)... [Pg.46]

Critical pigment volume concentration (CPVC) n. That level of pigmentation, PVC, value in the dry paint, where just sufficient binder is present to fill the voids between the pigment particles. At this level, a sharp break occurs in film properties such as scrub resistance, hiding, corrosion resistance, ease of stain removal, etc. Different requirements for each product would dictate different PVC or CPVC... [Pg.241]

Primers with low gloss have rougher surfaces and are easier to adhere to. When possible, increasing the pigment loading of a primer above critical pigment volume concentration (CPVC) facilitates adhesion of a topcoat. Above CPVC, the dry film contains pores when a topcoat is applied, vehicle from the topcoat penetrated into the pores, giving a mechanical anchor. [Pg.1425]

The pigment volume concentration influences solvent evaporation. Below the critical pigment volume concentration (CPVC) non-porous pigments act as barriers to solvent passage, whilst above the CPVC voids and polymer discontinuity affect solvent loss. At concentrations around the CPVC solvent evaporation rates are minimal. [Pg.378]
