Feature
Dry chemical powder SiO2 (silicon dioxide) is commonly used as a functional additive in plastic film paint formulations.
Here's how it can be applied in such coatings:
Matting Agent: SiO2 is often employed as a matting agent in plastic film paints to reduce gloss and provide a matte or satin
finish. Fine particles of SiO2 scatter light, resulting in a less reflective surface appearance.
Surface Modifier: SiO2 can act as a surface modifier, enhancing the adhesion of the paint to the plastic film substrate. This
helps improve the durability and longevity of the coating, reducing the risk of peeling or flaking.
Abrasion Resistance: Incorporating SiO2 particles into the paint formulation can enhance the abrasion resistance of the coating,
making it more durable and resistant to wear and tear, particularly important for plastic films subjected to handling and transportation.
Anti-blocking Agent: SiO2 can serve as an anti-blocking agent, preventing the painted plastic film from sticking together or
adhering to other surfaces during storage or use. This property improves the film's usability and maintains its quality.
UV Protection: Certain types of SiO2 particles can provide UV protection to the plastic film paint, helping to prevent color fading, degradation, and other forms of damage caused by exposure to sunlight. This is particularly beneficial for outdoor applications.
Improved Barrier Properties: SiO2 additives can enhance the barrier properties of the plastic film coating, reducing permeability
to gases, moisture, and other environmental contaminants. This property improves the film's performance in packaging applications
where barrier properties are critical.
When incorporating SiO2 into plastic film paint formulations, it's essential to consider factors such as particle size, surface treatment, dispersion stability, and compatibility with other paint components. Conducting thorough testing and evaluation of the coating's performance is crucial to ensure that the desired properties are achieved consistently in the final product.
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.
