Supreme™ Premium opacifying and thickening extender for decorative paints
Supreme™ premium kaolin from IMERYS gives
multiple benefits when used in decorative matt
wall paints, functioning both as an opacifying
extender and also as a rheology modifier.
The unique mineralogical make-up of the kaolin deposit
in Cornwall in the UK gives us a naturally fine platy product
that effectively spaces titanium dioxide particles in paint
formulations, as well as providing thixotropic thickening.
This allows a saving of up to 15% of the titanium dioxide in
the paint, and additionally reduces the thickener requirement.

Using specially selected feed from IMERYS’ deposits in
Cornwall, Supreme™ hydrous kaolin is engineered to an
ultrafine average particle size of 0.4μm to give optimal
spacing of titanium dioxide particles. This significantly
improves coating opacity, therefore allowing a
reduction in the TiO2 content of up to 15%.
As well as its exceptional opacity, Supreme™ brings unique
rheological properties to a paint.
The thixotropic low shear thickening effect allows a reduction
in the thickener requirement, or can be utilised to improve
anti-settling properties and sag resistance. It is particularly
beneficial in high quality matt paint formulations, and in
high gel strength paints.

The more thick and creamy the paint, the better in-can stability is achieved, which helps
to reduce syneresis. It also allows a reduction of expensive thickening agents.
At equivalent particle size, IMERYS UK hydrous kaolins give significantly better performance in terms
of low shear viscosity increases and gelling, with Supreme™ giving best performance of all kaolins.
