Product Description
High grade silica dioxide powder is commonly used in coatings due to its excellent properties. Silica dioxide, also known
as silica or silicon dioxide, is a naturally occurring mineral that is widely found in the earth's crust.
In coatings, high grade silica dioxide powder is used as a functional filler to improve various properties such as hardness,
scratch resistance, and durability. It can also enhance the adhesion and chemical resistance of coatings.
Here are some key benefits of using high grade silica dioxide powder in coatings:
1. Improved hardness: Silica dioxide powder can enhance the hardness of coatings, making them more resistant to scratches
and abrasion. This is particularly important in applications where the coating is exposed to high wear and tear.
2. Enhanced durability: Coatings with high grade silica dioxide powder have improved durability and can withstand harsh
environmental conditions, including exposure to UV radiation, moisture, and chemicals. This makes them suitable for outdoor
applications.
3. Increased adhesion: Silica dioxide powder can improve the adhesion of coatings to various substrates, including metals,
plastics, and glass. This ensures that the coating remains firmly bonded to the substrate, preventing delamination or peeling.
4. Chemical resistance: High grade silica dioxide powder provides coatings with excellent chemical resistance, protecting the
underlying substrate from damage caused by corrosive chemicals or solvents. This is particularly important in industrial or
chemical environments.
5. Improved flow and leveling: Silica dioxide powder can improve the flow and leveling properties of coatings, ensuring a
smooth and even application. This results in a high-quality finish with minimal defects such as brush marks or orange peel.
6. Reduced shrinkage and cracking: The addition of high grade silica dioxide powder to coatings can help reduce shrinkage
and cracking during the curing process. This ensures that the coating remains intact and provides long-lasting protection.
Overall, high grade silica dioxide powder is a versatile additive for coatings, offering a range of benefits such as improved
hardness, durability, adhesion, chemical resistance, flow, and leveling. Its use can enhance the performance and longevity
of coatings in various applications, including automotive, aerospace, marine, and industrial coatings.
