Welcome to Imerys Performance Minerals

VOC reduction

VOC reduction Imerys minerals with low resin demand are ideal for low-VOC coatings

Paint formulators can further reduce VOCs by using Imerys engineered functional products having lower resin demands. Imerys minerals are ideal for reducing VOC content of coatings, helping formulators meet increasingly stringent regulations governing VOC emissions, as well as their own Life-Cycle Assessment and sustainable development agendas.

Wollastonite

Nyad® wollastonite is a natural calcium metasilicate (CaSiO3). Its low oil absorption, unique mineralogy and acicular morphology make it an ideal extender for high performance, low VOC coatings:

Nyad® provides:

  • Improved mechanical properties
  • Enhanced corrosion resistance

It is ideal for:

  • Marine and protective coatings
  • Industrial coatings
  • Wind turbine coatings
  • Special purpose / OEM
  • Aerospace
  • Automotive refinishes
  • High heat resistant coatings
  • Pipe coatings

Diatomite

EcoFlatTM 1880, a natural hybrid high brightness diatomaceous earth matting aid product allows formulators to formulate a high PVC dead flat paint line without compromising the film properties and water demand in the grind phase. It allows the paint formulators to further reduce VOCs compared to typically high oil absorption matting aid products.

Carbonate

Imerys high brightness CaCO3 products are the excellent choice to formulate high solids coatings to reduce the VOC of the formulation. The lower oil absorption CaCO3 allows formulators to increase the loading level without any negative impact on the rheology of the paint formulation.

We recommend the following products:

  • Drikalite®
  • Gamaco®
  • Duramite®
  • #10 White®
  • Microwhite® 100

Talc

Imerys offers a range of talcs which not only combine chemical inertness and brightness, but have a low resin demand.

Using talc in solvent-based paints and primers allows manufacturers to:

  • Reduce the amount of additional solvent required for application
  • Achieve good filling rates 
  • Enhance anti-corrosion performance

We specifically recommend our talc chlorites and engineered talcs for high-build, low VOC coatings:

  • Mistron® 230
  • Steamas®
  • Luzenac 0
  • Luzenac ST 60
  • Mistron® 754 G 

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.
