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 is the most lamellar talc grade available to coatings formulators today. SteaShield™ 10 confers exceptional barrier properties to stain-blocking paints and corrosion resistant coatings, including coil and epoxy coatings.

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 paints, SteaShield™10:
- 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

EU REACh and Ecolabel
Imerys products for paints and coatings are 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, our products are exempt from EU REACH registration and compliant with EU Ecolabel criteria governing organic paints. Imerys minerals reduce the overall environmental impact of your paints and coatings formulations.
