QUANXU SILICA DIOXIDE POWDER (SN-230) M1

SKYSIL-ION SN-230 SILICA ANTI CORROSION PIGMENT

SN-230 silica anti-corrosive pigment serves as a high-performance functional material that elevates the overall performance of protective coating

systems. This product is professionally engineered to cater to the application demands of home appliances and construction materials.

Transformative Roles in Coating Systems

Barrier Architect

The lamellar particle structure of the pigment can form a dense layered matrix, which effectively compels corrosive substances including water molecules,

oxygen and chloride ions to pass through complicated and winding channels. As a result, the diffusion period of corrosive media is four times longer than

that of traditional spherical fillers. Even when the dry film thickness is controlled within 50 micrometers, the coating can still deliver outstanding salt spray

resistance exceeding 1,000 hours.

Rheology Modulator

With an ultra-low oil absorption value ranging from 40 to 60 grams per 100 grams, this product can greatly cut down the consumption of resin raw materials.

It brings multiple practical advantages for coating production and construction:

It supports the preparation of high-solid coatings without leading to a rise in system viscosity.

It significantly optimizes the flowability and leveling property during spray construction.

It effectively inhibits sagging issues on vertical surfaces, which has been verified through tests with 120 μm wet film.

pH Stabilizer

Functioning as an alkaline buffer agent with a pH value between 8 and 10, the pigment is capable of actively neutralizing acidic pollutants accumulated on metal

contact surfaces. Under the cyclic test environment with 85% relative humidity, it can thoroughly prevent the occurrence of osmotic blistering of coating films.

Adhesion Promoter

After professional surface modification, the particles can establish stable covalent chemical bonds with surrounding substances:

For epoxy and amine composite systems, Fourier transform infrared spectroscopy tests confirm that the crosslink density increases by 35%.

It forms firm combinations with hydroxyl groups on metal substrates. In accordance with the ASTM D4541 test standard, the adhesion strength is measured

above 5.5 MPa.
