Decorative Paints Imerys minerals - your dedicated solution for decorative paints and primers

Imerys offers a wide portfolio of engineered minerals for architectural paints. Imerys minerals make excellent, cost-effective multifunctional fillers and extenders, enhancing the optical and mechanical properties of interior and exterior decorative paints. 

Imerys minerals:

  • Improve dry hiding and opacity
  • Are effective TiO2 extenders reducing formulation costs
  • Enhance matting
  • Provide gloss control
  • Improve brightness
  • Reduce mud cracking and pinholing
  • Improve barrier properties and stainblocking
  • Improve impermeability of outdoor paints    
  • Provide breathability
  • Enhance burnish and scrub resistance
  • Provide UV and weather resistance
  • Improve acoustics and contribute to vibration damping
  • Contribute to VOC reduction
  • Enhance fire protection
  • Provide lightweighting
  • Improve rheology, paint adhesion and application
  • Are easy to disperse
  • Minimize settling


They are suitable for:

  • Water-based paints
  • Solvent-based paints
  • Gloss & semi-gloss finishes
  • Matt and ultra-matt paints
  • Primers and undercoats
  • Top coats


We also offer new tailor-made engineered solutions for TiO2-free paints.


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 decorative paints, Imerys talcs provide:

  • Matting
  • TiO2 extension
  • Barrier effect
  • VOC & resin reduction


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 decorative paints, Imerys kaolins provide:

  • TiO2 extension
  • Gloss control
  • Rheology modification
  • Opacity control

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 decorative paints, Imerys calcium carbonates provide:

  • Brightness
  • TiO2 extension
  • Opacity control
  • 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 decorative paints, Imerys DE provides:

  • Matting
  • TiO2 extension
  • Opacity
  • Breathability
  • Burnish & scrub resistance


Imerys leucophyllite

Leucophyllite is a unique coalescence of mica, quartz and chlorite. In decorative paints, Imerys leucophyllite can be used for:

  • Matting
  • Binder reduction
  • Scrub resistance

  • Anti-cracking


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 decorative paints, Imerys mica's provide:

  • Anti-cracking
  • Paint film flexibility
  • Barrier effect
  • Acoustic / vibration damping


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 decorative paints, Imerys perlites provide:

  • Matting
  • Lightweighting
  • Anti-pinholing
  • Burnish & scrub resistance


Imerys wollastonite

Wollastonite is a naturally occurring calcium metasilicate CaSiO3 mineral with an acicular particle shape. In decorative paints, Imerys wollastonite can be used for:

  • Low biocide paint formulations
  • Anti-cracking
  • Mechanical reinforcement
  • Gloss control
