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

Cost Effective Opacity - A Natural Alternative to Opaque Polymer

Flash calcined kaolin and opaque polymer are competing technologies that can exert a direct influence on the optical properties of interior decorative matte emulsion paint. Flash calcined kaolin’s intrinsically sealed voids and opaque polymer air voids both act as scattering sources that
make a direct contribution to dry film opacity...read more
