Welcome to Imerys Performance Minerals

Industrial coatings

Industrial coatings Imerys minerals improve the all-round performance of industrial paints and primers and coatings

Industrial coatings are used to protect a wide range of substrates such as metals, plastics and wood which are exposed to extreme environmental conditions. Imerys minerals provide solutions to boost corrosion resistance and enhance mechanical performance at excellent surface finish. Imerys minerals are excellent solutions for reducing coating VOC content to meet the most stringent environmental regulations.

Used in industrial topcoats and primers, Imerys minerals:

  • Are effective TiO2 extenders reducing formulation costs
  • Improve barrier properties enhancing impermeability and corrosion resistance
  • Provide superior mechanical performance
  • Enhance surface finish
  • Provide gloss control
  • Enhance matting
  • Contribute to VOC and binder reduction to meet the most stringent environmental regulations
  • Enhance abrasion, burnish and scrub resistance
  • Provide UV and weather resistance
  • Provide lightweighting
  • Improve rheology, paint adhesion and application
  • Are easy to disperse
  • Minimize settling


They are suitable for:

  • Coil coatings
  • Powder coatings
  • Marine & protective coatings
  • General metal coatings
  • Automotive coatings
  • Wood protection
  • Gel coats
  • Putties and body fillers

An extensive portfolio


Imerys talc

Talc is a hydrated magnesium silicate, Mg3Si4O10(OH)2 which is water repellent, lamellar and inert. It is the softest mineral on earth. In industrial coatings, Imerys talcs provide:

  • Anti-corrosion

  • TiO2 reduction    

  • Low VOC


Imerys kaolin

Kaolin is a hydrated aluminum silicate crystalline mineral, Al2Si2O5(OH)4 formed by the hydrothermal decomposition of granite rocks. It is available as hydrous, calcined or in flash calcined form for paint and coating applications. In industrial coatings, Imerys kaolins are suitable for:

  • TiO2  reduction    

  • Gloss control

  • Rheology modifier

Calcium Carbonate

Imerys ground calcium carbonate

Ground Calcium Carbonates (GCC) occur in three principal forms: chalk, limestone and marble. Precipitated Calcium Carbonate (PCC), has a very pure crystal form, and can be tailored to a variety of different shapes and sizes. In industrial coatings, Imerys calcium carbonates provide:

  • Brightness
  • TiO2 reduction
  • Gloss control

Diatomaceous Earth

Imerys diatomaceous earth

Diatomaceous Earth (DE) is a natural amorphous silica product, >90% Si02 consisting of a unique mix of fossilised aquatic plants. It is available in natural and flux calcined forms. In industrial coatings, Imerys DE can be used for:

  • Matting

  • TiO2 reduction    

  • Abrasion resistance


Imerys leucophyllite

Leucophyllite is a unique coalescence of mica, quartz and chlorite. In decorative paints, Imerys leucophyllite confers:

  • Film hardness

  • Abrasion resistance

  • Binder reduction


Imerys mica

Mica is a natural highly lamellar mineral. Imerys offers muscovite mica, a potassium aluminium silicate, and phlogopite mica, a potassium / magnesium aluminium silicate, formed by the hydrothermal decomposition of granite rocks. In industrial coatings, Imerys mica's provide:

  • Anti-corrosion

  • Barrier effect

  • Adhesion


Imerys perlite

Perlite is a volcanic rock, a naturally amorphous alumino-silicate, with 70-75% SiO2 and 12-15% Al2O3. It is selectively mined, expanded, milled and surface modified to provide a wide range of functionalities in paints. In industrial coatings, Imerys perlites impart:

  • Matting

  • Lightweighting

  • Transparency


Imerys wollastonite

Wollastonite is a naturally occurring calcium metasilicate CaSiO3 mineral with an acicular particle shape. In industrial coatings, Imerys wollastonite confers:

  • Anti-corrosion

  • Mechanical reinforcement

  • High gloss
