Stainblocking & barrier properties Highly lamellar Imerys minerals for superior stain-blocking performance
Ultra lamellar Imerys micas and kaolins provide exceptional barrier properties in stain-blocking paints and primers.
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.
Paints & coatings
Our C4000, WG325, Suzorite® 325-G, Suzorite® 500-G are muscovite mica products and are highly lamellar shaped for efficient barrier formation and light colored for waterborne and solvent borne primer applications.
Both are cost-effective, easy-to-formulate stain-blocking solutions that function with both solvent and water-based systems.
Likewise, our Hydrite® SB60 and Hydrite® SB100 are high aspect ratio kaolins which have been mechanically proceeded to fully separate the individual plates. This increases the aspect ratio to produce a highly lamellar pigment. The platy nature of the product increases barrier properties such as stain resistance and improves the stain blocking performance in waterborne coatings.
