Product details

SKYSIL HF-685 SILICA MATTING AGENT FOR COIL COATING

- Ultra-thin coating matting optimization

Nano-scale particles (primary particle size 10-20nm) are evenly distributed in a 10-15μm thin coating, and the quantum size effect enhances light

absorption, reducing the reflectivity of the 85° high light area by 40%, solving the problem of light transmission and brightness of traditional matting

agents on metal substrates.

- Self-assembly protective layer construction

Dynamic wetting control: Fluorocarbon segments migrate to the coating surface in a directional manner during the baking stage to form a dense

protective film, with a pencil hardness of 3H-4H and a 50% increase in sand and dust impact resistance (ASTM D968).

- Weathering enhancement: After 2000h QUV aging test, ΔE <1.2, fluorine and silicon synergistic effect effectively blocks ultraviolet degradation,

and the light retention rate is >92%.

- Upgraded anti-pollution: surface energy is reduced to 18-22mN/m, oil contact angle>110°, achieving self-cleaning effect (70% reduction in

pollutant adhesion).

- Process adaptability: the dispersion time is shortened by 60% in 5000-8000s⁻¹ high shear roller coating, the coating viscosity fluctuation is <5%, and

it is suitable for 800m/min ultra-high-speed production line.

- Cost optimization: the addition amount is only 2-4% (traditional products require 5-8%), reducing resin consumption by more than 20%, and reducing

the cost of a single ton of coating by 15-18%.

HF-685 redefines the technical boundaries of matting agents for coil coatings through the deep synergy of vapor phase nano-engineering and surface

chemistry, providing the industry with an innovative solution that combines "ultra-thin matte - extreme protection - green cost reduction", and promoting

the upgrading of metal coatings to high performance and sustainability.
