In modern anticorrosive coating formulations, silica serves a vital multi-functional role. It acts as a thickener, thixotropic agent and anti-settling
additive all in one. Its thickening and suspending capabilities help evenly distribute fillers and functional ingredients throughout the resin system,
effectively preventing sedimentation and inconsistent formulation quality. Additionally, its unique thixotropic behavior greatly improves on-site
construction performance. The coating resists sagging even when applied at thicker film builds, allowing smoother, more uniform application across
different working conditions.
Built for household equipment and metal construction materials, SKYSIL-ION SN-900 is a high-performance silica anti-corrosion pigment that significantly
upgrades coating protection. This refined white powder leverages tailored silica characteristics to better preserve metal surfaces and extend service life,
especially for substrates exposed to harsh outdoor and industrial environments.
1. Higher Oil Absorption (80–100 g/100g)
This tailored absorption range optimizes interaction between the pigment and coating binders. It stabilizes overall rheological behavior, making spraying
and rolling applications much smoother. The final film forms more uniformly and maintains better structural integrity after curing.
2. Balanced Alkaline pH Value (7.0–9.0 in 5% aqueous solution)
The product maintains a mild alkaline environment at the metal interface, which actively neutralizes acidic pollutants that trigger corrosion. Its balanced alkalinity
avoids incompatibility issues and works steadily with common alkaline-resistant resin systems, including epoxy and polyurethane.
3. Fine and Consistent White Powder Texture
SN-900 features uniform particle consistency, ensuring stable, repeatable dispersion in production batches. It delivers reliable color uniformity and avoids tone
deviation in finished coatings, which is critical for appliance and architectural coating applications.
Active and Passive Dual Protection Mechanism
What sets SN-900 apart from standard anti-corrosion pigments is its combined protective system. The alkaline composition provides continuous chemical inhibition
to suppress early-stage corrosion. At the same time, densely packed silica particles form a compact physical barrier that blocks moisture, oxygen and salt ions from
reaching the metal substrate.
This two-way protection delivers far more durable results than traditional single-function pigments. It performs exceptionally well in high-humidity, coastal and saline
environments where metal degradation typically occurs at a faster rate.
By upgrading your coatings with SKYSIL-ION SN-900, you gain stronger corrosion resistance, more stable construction performance, and longer asset service life.
It effectively reduces long-term maintenance costs for both household metal products and industrial metal infrastructure, bringing upgraded and reliable silica-based
protection to your coating solutions.
