SKYSIL-ION SN-930 SILICA ANTI CORROSION PIGMENT

Corrosion has long been a tricky problem across automotive, construction, marine and many other industrial sectors. It gradually erodes metal materials,

shortens the service life of equipment and structures, and even brings about hidden safety risks in practical use. For this reason, anticorrosive coatings

have become an indispensable solution for metal protection in industrial production and daily applications.

Silica-based anticorrosive pigments serve as a key functional component in modern protective coatings. Incorporated into paint formulas, these pigments

effectively block water infiltration, which greatly curbs the occurrence of corrosive chemical reactions on metal surfaces.

Tailored specifically for home appliance and metal construction material applications, our SN-930 silica anticorrosive pigment delivers stable, high-efficiency

corrosion protection adapted to actual coating construction needs.

1. Optimized Oil Absorption (55–75 g/100 g)

This moderate oil absorption value allows the pigment to blend seamlessly with various coating formulas. It not only simplifies the batching and mixing process

but also effectively improves the flexibility and substrate adhesion of the cured coating film.

2. Moderate High Alkalinity (pH 8–10 in 5% Aqueous Solution)

The product features a stable alkaline buffer property. It can actively neutralize acidic impurities gathered at the metal-coating interface to suppress corrosion

reactions. It matches perfectly with epoxy and polyurethane coating systems, delivering reliable and lasting anti-corrosion effects.

3. Uniform Ultrafine White Powder Texture

With a fine and consistent powder particle state, SN-930 supports the production of thin yet high-performance coatings. It maintains complete barrier integrity

of the film without relying on thick coating layers, balancing construction aesthetics and protective performance.

4. Dual Anti-Corrosion Defense Mechanism

Different from traditional single-function anticorrosive pigments, SN-930 adopts a synergistic dual protection system. Its ultrafine particles stack tightly in the

coating to form a dense physical barrier that isolates external corrosive media. Meanwhile, its sustained alkaline activity neutralizes early corrosive behaviors

on metal substrates. This dual working mode provides solid targeted protection for metal products in harsh scenarios such as coastal salt fog, industrial pollution

and high-humidity environments, where corrosion deterioration is highly likely to accelerate.
