QUANXU SILICA DIOXIDE POWDER (SL-712) M1

SKYSIL SL-712 SILICA POWDER FOR INDUSTRIAL COATING

SL-712 is a high effieciency silica matting agent that is equal to Grace ED5, no matter is chemical parameters or usage industries. With special

wax treatment on surface, it can provide double functions including precise matte effect and long-lasting protection.Extreme operating tolerance:

99.0% silica content (dry basis) combined with ≤7.0% loss on ignition (1000°C) keeps residual impurities below the industry standard of 60%,

completely blocking siloxane migration in a 230°C baking environment. The active silanol groups retained on the original, untreated surface

(NONE) increase the catalytic cure rate in epoxy coal tar systems by 18%, and pass a 2400-hour neutral salt spray test (ISO 9227) to verify

long-term protection. Its weakly acidic nature (pH 6-7, 5% solution) provides a key guarantee for chemical stability, inhibiting yellowing in

amine-catalyzed construction machinery primers. The ΔE value of the light gray coating remains stable at ≤0.8, extending the outdoor color

life to 5 years.

1. Chemical properties are equal to Grace ED5

- High purity amorphous structure: content of SiO2 is more than 99.3%. The content of impurity ions is less than 100ppm, ensuring the

yellowing resistance and chemical stability of the coating.

- Controllable porosity design: Through the precipitation silicate polycondensation process, a through-hole structure with a pore size of 5-20nm is

formed, giving the coating efficient light scattering ability, and the glossiness at 60° angle can be adjusted from 2-90GU.

2. Matting performance and protection mechanism

- Dynamic matting enhancement

The wax treatment layer produces microphase separation during the film-forming stage of the coating, and cooperates with the porous structure of

silica to form a composite rough surface of "micron-level depressions + nano-level protrusions", which causes diffuse reflection of incident light. The

matting efficiency is increased by 25% compared with the untreated product, and a uniform matte effect can still be maintained in a high film thickness

(>100μm) system.

3. Industrial application value

In the field of engineering machinery and ship coatings, SL-712 can achieve single-coat matte protection, replacing the traditional "primer + matte

topcoat" system, simplifying the process and reducing costs by 18-22%. Its wax protective layer characteristics are particularly suitable for cold chain

equipment, chemical storage tanks and other scenes that require anti-condensation and anti-corrosion, and its performance is stable in the temperature

range of -40℃~150℃.

SL-712 redefines the performance boundaries of industrial coating matting agents through chemical performance benchmarking and surface engineering

innovation, providing solutions for high-end equipment manufacturing that combine aesthetic texture and long-term protection.
