Enhanced mechanical properties
Large-particle silica sol has larger particles and stronger aggregation and mechanical strength. In practical applications, this type of silica sol can enhance the hardness and compressive resistance of materials, so it is often used to enhance the durability of coatings, composite materials, etc. Its larger particles can form a stronger structure in coatings or composite materials, provide additional support, and improve the overall performance of materials.
Better thermal stability
Due to the larger silica particles in large-particle silica sol, their stability in high-temperature environments is more outstanding. Large-particle silica sol has good high-temperature resistance and can remain stable for a long time under high-temperature conditions above 500°C, so it is widely used in high-temperature coatings, ceramics and casting.
Excellent UV resistance
Large-particle silica sol exhibits excellent UV shielding properties. In some applications that require UV resistance, such as outdoor coatings and solar photovoltaic materials, large-particle silica sol can effectively block UV radiation, extend the service life of the material and reduce UV damage to the surface of the object.
Improved rheology and processing properties
Large-particle silica sol exhibits better rheology during processing and application. It can form a uniform distribution in the coating and reduce precipitation, thus making the coating and other colloidal materials have higher fluidity and better workability. Compared with traditional small-particle silica sol, it is more stable during the coating process and is suitable for large-area coating and complex surface treatment.
