Characteristics
When selecting a SiO2 Matting Agent for matte paper coating paint, you'll want to consider several factors to achieve the
desired finish and performance. Here are some key considerations:
Particle Size: Choose a SiO2 matting agent with the appropriate particle size distribution to achieve the desired level of
matte finish. Fine particles generally result in a smoother surface and a more uniform matte appearance.
Matting Efficiency: Consider the matting efficiency of the SiO2 agent, which determines how effectively it reduces
glossiness and creates a matte effect on the paper surface. Higher matting efficiency allows for lower usage rates, reducing
costs and potential negative impacts on other coating properties.
Surface Roughness: The surface roughness generated by the SiO2 matting agent should be optimized to achieve the desired
tactile feel and visual appearance of the matte paper coating. Too much roughness may compromise printability or cause issues
with image quality.
Transparency: Ensure that the SiO2 matting agent maintains the transparency of the coating to preserve the brightness and
color vibrancy of printed or coated materials. Excessive opacity can lead to dull or muted colors.
Dispersion Stability: The SiO2 matting agent should disperse evenly and uniformly in the paint formulation to achieve consistent
matte effects across the paper surface. Good dispersion stability prevents issues such as agglomeration or uneven coating.
Compatibility: Verify that the SiO2 matting agent is compatible with other components in the paint formulation, including binders, pigments, and additives. Compatibility testing is essential to ensure that the matting agent does not negatively affect coating
performance or stability.
Film Properties: Consider the impact of the SiO2 matting agent on other film properties, such as hardness, flexibility, and abrasion resistance. The matting agent should not compromise the overall durability or integrity of the paper coating.
Regulatory Compliance: Ensure that the SiO2 matting agent complies with relevant regulatory standards and safety requirements
for use in paper coatings, 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.
