Industrial assets need coatings that stand up to moisture, chemicals, and abrasion. SPHERILEX® AC 45 and AC 45 HS from Evonik deliver exceptional, long-lasting corrosion protection with a safer and more sustainable profile.
Why SPHERILEX® AC is the next generation in anti-corrosion pigments
Engineered with a unique 94% silica / 6% calcium oxide composition and spherical particle morphology, SPHERILEX® AC pigments disperse easily, resist clumping, and deliver uniform protection across substrates.
In waterborne 2K epoxy primers, they achieved:
- >1500 hours salt spray resistance (ASTM D1654)
- With half the dosage of traditional anti-corrosion pigments
This means lower material usage, reduced environmental impact, and consistent long-term performance.
Their spherical morphology ensures easy dispersion and consistent performance across substrates.
Key Benefits
- Superior anti-corrosion performance
- Strong abrasion resistance
- Lower pigment demand = cost savings
- Label-free, sustainable alternative
- Simple integration into existing formulations
