Characteristics
When considering the paint material used for Matte Photo Paper, SiO2 powder (silicon dioxide) can be employed as a
Matting Agent to achieve the desired matte finish. Here's how SiO2 powder is typically utilized in the production of matte
photo paper:
Matting Agent: SiO2 powder serves as a matting agent in the coating formulation for matte photo paper. It is added to the
coating mixture to reduce glossiness and create a matte surface texture on the paper.
Particle Size and Distribution: The particle size and distribution of SiO2 powder are carefully controlled to achieve the
desired level of matte finish. Fine particles contribute to a smoother texture and more uniform coating appearance.
Surface Modification: Surface-treated SiO2 particles may be used to enhance compatibility with other coating components
and improve dispersion within the coating formulation. Surface modification can also influence properties such as adhesion,
printability, and resistance to abrasion.
Opacity and Transparency: SiO2 powder should maintain the opacity of the coating while preserving the clarity and brightness
of printed images. It's essential to balance opacity with transparency to ensure optimal printing results on matte photo paper.
Soft Texture: Depending on the desired texture of the matte photo paper, SiO2 powder can contribute to a soft and velvety feel.
The particle morphology and surface properties of SiO2 powder can influence the tactile qualities of the coated paper.
Dispersion Stability: SiO2 powder should disperse evenly and uniformly in the coating formulation to achieve consistent matte
effects across the photo paper surface. Good dispersion stability helps prevent issues such as agglomeration or uneven coating.
Compatibility: SiO2 powder should be compatible with other coating components, including binders, pigments, and additives
used in the formulation. Compatibility testing is essential to ensure that SiO2 powder does not negatively impact coating
performance or stability.
Regulatory Compliance: SiO2 powder used in matte photo paper coatings should comply with relevant regulatory standards
and safety requirements for paper products, including restrictions on chemical composition, toxicity, and environmental impact.
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.
