Both the necessary thickness and the cost of opacity were found to decrease as the [TiO.sub.2] concentration increased, again illustrating titanium dioxide's superior opacifying power.
The organic opacifying polymer, AQAcell HIDE 6299 was also launched during the show.
An example is our ROPAQUETM[TM] Hollow Sphere Pigment (HSP) Technology, which can be used as opacifying agents to significantly reduce the use of more expensive [Ti0.sub.2]," he comments.
This capacity is the filler's opacifying efficiency, which is a function of particle size, shape, and refractive index.
