Product Introduction:
Large particle size silica dioxide powder is commonly used in coatings for various applications. It provides several benefits,
including improved scratch resistance, enhanced durability, and increased surface hardness.
The large particle size of silica dioxide powder allows for better filling and leveling properties, resulting in a smoother and
more uniform coating surface. It also helps to reduce shrinkage and cracking during the drying and curing process.
Additionally, large particle size silica dioxide powder offers excellent UV resistance, which is crucial for coatings exposed to
sunlight. It acts as a barrier, preventing the degradation of the underlying substrate and prolonging the lifespan of the coating.
Furthermore, the large particle size of silica dioxide powder improves the flow and viscosity of the coating formulation, making
it easier to apply and control. This property is particularly beneficial for thick coatings or those applied on vertical surfaces.
Overall, large particle size silica dioxide powder is an essential ingredient in coatings, providing numerous advantages such
as improved scratch resistance, enhanced durability, increased surface hardness, UV resistance, and improved flow and
viscosity.
