The role of gas silicon in the coating is mainly as follows:
No.1 improves rheological properties
Coatings begin to exhibit thixotropy when the rise and fall of the viscosity depends not only on the shear rate but also on the duration of the shear stress and the stop time. The three - dimensional network structure formed by gas silicon can improve the rheological properties of coating system.
No.2 is used as anti-settling agent
No matter the hydrophilic gas silicon or the treated gas silicon, the three-dimensional network structure formed can effectively prevent the settling of pigments and fillers in the coating system.
No.3 Coating


Experiments have shown that if zinc powder and 0.5% treated gas silicon are mixed in a blender without any other additives, the hydrophobic silica will be fully coated on the zinc powder. The coating of gas silicon around zinc powder may be caused by electron interaction. Under these conditions, the synthetic silica is negatively charged, while the metal is positively charged. Coating does not in any way reduce the resistance to galvanic corrosion conferred by zinc dust.
No.4 is used as a dispersion agent


The dispersion ability of pigment can be improved obviously by adding a small amount of hydrophobic gas silicon.
No.5 to improve the rust resistance


The anti-rust properties of zinc powder paint can be improved by adding hydrophobic gas silicon, and the anti-rust properties of zinc powder paint can be improved by adding hydrophobic gas silicon in a formula that does not contain anti-rust pigment, such as a high solid polyester/amino resin industrial varnish.
No.6 improves the fluidity of powder coatings


Silicon has been widely used in many industrial fields to improve the powder coating, liquid hydrophobic gas silicon is particularly effective, hydrophobic gas silicon technology applied in the improvement of powder coatings, and either positively or negatively charged, gas silicon can join in grinding process of powder coating, can also join after grinding.
