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 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.

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, 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
