Muscovite Mica C4000, WG 325, Suzorite 325-G and Suzorite 500-C For superior barrier properties in stain blocking primers
- Excellent stain blocking performance
- Reinforced barrier effect significantly limits stain migration
- Cost effective and easy to formulate
Imerys muscovite mica are highly lamellar, micronized and high aspect ratio products. Due to this high lamellarity, they provide excellent stain blocking performance in primer applications.
Recommended for solvent- and water-based primer applications requiring superior stain-blocking.
Muscovite mica:
- Improves barrier protection over time, significantly limiting stain migration
- Enhances adhesion and anti-cracking
- Improves UV protection in paints
- Is a cost-effective and easy-to-formulate solution
Due to its ultra-lamellar particle shape Mica creates a physical barrier in the paint film
