For a long time, organic coatings have been widely used for its good decorative properties, variety and low price. However, since the main raw materials of organic coatings come from natural resources such as coal, oil and natural gas, a large number of by-products, volatile solvents and residual monomers will be produced during processing, which will cause environmental pollution and waste a lot of resources and energy.
With the increasing emphasis on environmental protection and energy conservation, more environmentally friendly and energy-saving inorganic coatings and coating additives represented by silicon dioxide (silicate) have received more and more attention, and its application development in the coating field has become more and more in-depth.
Improve coating performance
Enhanced durability: Surface-modified silica particles are added to the coating to significantly enhance the durability and corrosion resistance of the coating, protecting steel structures and engineering equipment.
Enhanced hardness: Silica itself has a certain strength. When added to the coating, it can increase the hardness of the coating, making it more wear-resistant and scratch-resistant.
Improve the rheological properties: Silica can improve the rheological properties of the coating, making it thixotropic and easier to construct and apply.
Improve coating appearance
Improve glossiness: A proper amount of silica can improve the glossiness of the paint, making it more beautiful.
Reduce color difference: Nano silica can effectively reduce the color difference of the paint caused by ultraviolet and infrared light, and improve the anti-aging property of the exterior wall paint.
Give coating special functions
Self-cleaning function: Surface-modified silica can be used as an additive to make the coating have a self-cleaning function, which can effectively prevent the generation of dirt and bacteria.
Photocatalytic function: Silica is added to UV-curing coatings to improve the wear resistance, hardness, impact strength and flexibility of the coating, while also improving the curing speed, coating hardness, adhesion and thermal stability of UV-curing coatings at low temperatures.
Environmental protection and energy saving
Replacement of organic solvents: In environmentally friendly water-based coatings, surface-modified silica particles can increase the adhesion and durability of the coating while reducing the use of organic solvents, which is beneficial to environmental protection.
