SteaShield 10

SteaShield 10 For exceptional barrier properties in stain-blocking paints and corrosion resistant coatings

  • Improved barrier properties and corrosion resistance
  • Excellent stain-blocking performance
  • Easy to formulate

Ultra-lamellar SteaShield 10 talc confers exceptional barrier properties to stain-blocking paints and corrosion resistant coatings, including coil and epoxy coatings.

SteaShield™ 10 is the most lamellar talc grade available to coatings formulators today

The ultra-lamellar particle shape of SteaShield 10 creates a physical barrier which protects the paint substrate by impairing the diffusion of water and corrosive agents through the film.

Corrosion resistant coatings

In corrosion resistant coatings, SteaShield 10: 

  • Provides unparalled barrier properties and corrosion resistance 
  • Demonstrates excellent salt-spray resistance 
  • Minimizes settling
  • Is easy to formulate

SteaShield 10 is ideal for coil and epoxy coatings.

Stainblocking paints

In stain-blocking finishing paints, SteaShield10: 

  • Improves barrier protection over time, significantly limiting stain migration
  • Is easy to formulate
  • Functions with solvent and water-based systems
  • Enhances anti-cracking, adhesion and UV protection in paints
  • Is a cost-effective solution


For stainblocking primers, we recommed our Mica MU 2/1 grade.

EU REACh and Ecolabel

Ecolabel logo

Steashield 10 is derived from naturally occurring, chemically inert minerals that are simply ground to achieve a specific particle distribution size. We do not use additives in our processes. As such, it is exempt from EU REACH registration and compliant with EU Ecolabel criteria governing organic paints.

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.
