When selecting a SiO2 powder for black leather paint, several factors should be considered to ensure the desired appearance,
durability, and performance of the painted leather. Here's what to look for in the best SiO2 powder for black leather paint:
Pigment Dispersion: The SiO2 powder should disperse evenly in the paint formulation to ensure uniform color coverage
and prevent streaks or unevenness in the painted leather surface.
Color Stability: Choose a SiO2 powder that maintains color stability when mixed with black pigments and other additives
in the paint formulation. Color consistency is essential for achieving the desired shade of black and preventing color shifting
over time.
UV Stability: The SiO2 powder should be UV stable to prevent color fading or degradation of the black leather paint when
exposed to sunlight or other UV radiation. UV-stabilized SiO2 particles help maintain the color intensity and vibrancy of the
painted leather over time.
Adhesion: Surface-modified SiO2 particles can enhance adhesion to the leather surface, improving the durability and
longevity of the paint finish. Good adhesion ensures that the paint remains bonded to the leather and resists flaking or
peeling.
Flexibility: The black leather paint should remain flexible and resistant to cracking or creasing, even after repeated bending
or flexing of the leather surface. Choose a SiO2 powder that enhances the flexibility and elasticity of the paint film on the leather.
Abrasion Resistance: SiO2 additives can improve the abrasion resistance of the black leather paint, ensuring that it withstands
friction and wear without showing signs of damage or deterioration.
Water and Stain Resistance: Consider SiO2 powders that provide water and stain resistance to the black leather paint, protecting
it from spills, moisture, and other environmental contaminants. Water-repellent and stain-resistant properties help maintain the appearance and durability of the painted leather.
Regulatory Compliance: Verify that the SiO2 powder meets relevant regulatory standards and safety requirements for use in
leather paints, particularly concerning chemical composition, toxicity, and environmental impact.
