Durable titanium dioxide extender for high quality matt paints


Opacilite™ is the ideal titanium dioxide extender and opacifier for high quality matt paints.


Providing durability and exceptional opacity both above and below the CPVC of a coating, Opacilite™ is the first choice for TiO2 extension in high quality matt and silk paints.

Opacilite™ flash calcined kaolin offers:-

Opacilite™ is a naturally-sourced mineral product allowing significant cost savings


The intrinsically sealed voids of the aggregated structure are optimised for maximum light scattering and give Opacilite™ its characteristic properties. Sealed rather than open voids result in better wet opacity, and allow dry hiding to occur even below the CPVC of the coating.

The high durability of Opacilite™ makes it particularly suitable for use in high quality paints.
