Anti-cracking

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.

Lamellar Plastorit® leucophyllite grades are ideal for preventing cracking in low-VOC paints, marine and protective coatings, metal topcoats and primers and powder coatings.

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.

Platy talc-chlorites such as our Steopac® and Steabright® grades demonstrate superior cracking resistance in alkyd emulsions and acrylic paint formulations.

Extra M100 is an ideal solution for preventing cracking and pinholes in exterior wall plasters.

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.
