Feature
SiO2 powder can be used as a UV topcoat for various applications. SiO2, also known as silicon dioxide or silica, is
a commonly used material for its high refractive index, transparency, and UV resistance.
When used as a UV topcoat, SiO2 powder can provide several benefits:
1. UV Protection: SiO2 powder can act as a barrier against harmful UV radiation, protecting the underlying material from
fading, yellowing, or degradation caused by sun exposure.
2. Scratch Resistance: SiO2 powder can enhance the scratch resistance of the coated surface, providing a durable and
long-lasting protective layer.
3. Water Repellency: SiO2 powder can create a hydrophobic surface, repelling water and preventing water spots or stains
from forming on the coated surface.
4. Easy Cleaning: SiO2 powder can make the coated surface easier to clean by repelling dirt, dust, and other contaminants.
This can reduce the need for frequent cleaning and maintenance.
To apply SiO2 powder as a UV topcoat, it is typically mixed with a suitable solvent or binder to form a coating solution. The
solution can then be applied using various methods such as spraying, dipping, or brushing onto the desired surface. After
application, the coating is usually cured or dried to form a solid and protective layer.
It is important to follow the manufacturer's instructions and recommendations for proper handling, application, and curing of
SiO2 powder to achieve the desired UV topcoat properties.
USING TIPS:
* Recommend dosage is 3%-8%. (Please adjust the dosage according to the actual product.) * As different formulations and conditions, suggest the user to test and make sure the dosage before using.
