Specification
High purity silicon matting agents are commonly used in plastic coatings to achieve a matte or satin finish. These matting
agents are made from high-quality silicon dioxide (SiO2) particles that are carefully engineered to provide consistent and
uniform matting effects.
The main purpose of using a Matting Agent in plastic coatings is to reduce the glossiness of the surface and create a more
aesthetically pleasing appearance. This is particularly important in applications where a glossy finish is not desired, such as
in furniture, automotive interiors, electronic devices, and packaging materials.
High purity silicon matting agents offer several advantages in plastic coatings. Firstly, they provide excellent transparency,
allowing the underlying color and texture of the plastic substrate to show through. This is particularly important for transparent
or translucent plastics, where maintaining clarity is crucial.
Secondly, these matting agents offer good scratch and abrasion resistance, ensuring that the coating remains durable and
long-lasting. They also provide good chemical resistance, preventing the coating from being damaged by common household
chemicals, solvents, or cleaning agents.
Furthermore, high purity silicon matting agents are easy to disperse and incorporate into various coating systems, including
water-based, solvent-based, and UV-curable formulations. They can be used in combination with other additives, such as
rheology modifiers, leveling agents, and defoamers, to optimize the coating performance and application properties.
In summary, high purity silicon matting agents are essential additives in plastic coatings to achieve a desired matte or satin finish.
They offer excellent transparency, scratch resistance, chemical resistance, and ease of dispersion, making them suitable for a
wide range of plastic coating applications.
