A new generation of high performance Opacifier

Opacilite™ is a high whiteness “flash calcined” kaolin produced by a revolutionary new rapid heating process. This patented technique creates large numbers of intrinsically sealed voids within the clay particles. These tiny voids provide outstanding opacifying properties in coatings below and above the critical pigment volume concentration (CPVC), specifically less than 65% PVC. In addition, the low specific gravity provides an inherent volume cost saving. The presence of these sealed voids distinguishes Opacilite from conventional mineral extenders. Opacilite also has external voids on its surface, which contribute to opacity above CPVC.

Opacilite™ flash calcined kaolin offers the following important benefits in emulsion paints :-

	High dry film opacity
	Good wet film opacity
	Cost savings via reduced levels of TiO₂ pigment
	Cost savings via reduced paint specific gravity
	Good whiteness and low yellowness
	Excellent scrub resistance

These benefits are achievable in a wide range of emulsion or latex based paints, both below and above the CPVC, including:-

	Satin and eggshell finishes for wood and walls
	Mid sheen (soft sheen) emulsion paints for walls
	Exterior masonry paints
	Primers
	Matt emulsion paints
