Welcome to Imerys Performance Minerals


Anti-cracking Imerys Minerals for superior anti-cracking performance in interior and exterior decorative paints and industrial coatings

Imerys platy minerals help to reduce mud cracking by preventing crack propagation within the film.

The lamellar particles interact with paint binders and other components in the paint creating resistance to tensions that build up in the drying film as it shrinks which:

  • prevents mud cracking, surface cracking and flaking
  • improves coating appearance and durability.

The higher the aspect ratio and particle size, the better the cracking resistance.

Platy Imerys talcs such as our Vertal® grades demonstrate superior cracking resistance in alkyd emulsions and waterborne acrylic paint formulations.

Lamellar Imerys mica grades are optimum products for improving mud crack resistance in protective and OEM coatings, sealant primers and decorative paints.

Nyad® wollastonite grades reduce cracking and checking in high-performance, low-VOC industrial coatings. They are also ideal anti-cracking agents in floor mortars.

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.
