Stainblocking & barrier properties Ultra lamellar Imerys minerals for superior stain-blocking performance
Ultra lamellar Imerys talcs and micas provide exceptional barrier properties in stain-blocking paints and primers.
Paints & coatings
The highly lamellar particle shape of these minerals creates a physical barrier which protects the paint substrate by impairing the diffusion of water and corrosive agents through the film, preventing stain migration over time.
Stain migration over time
Our SteaShield™ 10 talc grade is produced using an innovative, proprietary, milling process which dramatically increases lamellarity.
SteaShield™ 10 provides exceptional barrier properties in finishing paints and primers.
Our Mica MU™ M2/1 product is a highly lamellar grade with a 20µm top cut. Mica MU™ M2/1 is recommended for primer applications.
Both SteaShield™ and Mica MU™ M2/1 are cost-effective, easy-to-formulate stain-blocking solutions that function with both solvent and water-based systems.
Likewise, our Barrisurf™ very high aspect ratio kaolins are excellent solutions for improving stain blocking.
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.
