Stain blocking and barrier properties

Stainblocking & barrier properties Ultra lamellar Imerys minerals for superior stain-blocking performance

Ultra lamellar Imerys talcs 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.
