Welcome to Imerys Performance Minerals

Weather & UV resistance

Weather & UV resistance Imerys minerals enhance weather and UV resistance

Imerys minerals protect water-borne and solvent-borne binders from UV radiation, enhancing the weather resistance of outdoor paints and primers.


Our leucophyllite-based products, Eco-Phyl® and Plastorit® are derived from a unique coalescence of chlorite, mica and quartz.  Eco-Phyl® and Plastorit® have a lamellar particle shape which improves the mechanical properties, weather and color resistance of paints and coatings.


Nyad® wollastonite grades have a needle-like structure which reinforces coating films, providing durability, superior weather and color retention. They are ideal for improving weather and UV resistance in decorative paints and industrial, protective and marine coatings.


Opacilite calcined kaolin significantly improves weather and UV resistance compared to other mineral pigments such as conventional kaolin and calcium carbonates.



We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
