SiO2 Matting Agent For Paper Coating Paint

H-903 Silica Matting Agent

We often use silicon dioxide powder as matting agent in matte paper coating. Silicon dioxide is a iroganic substance, it 

has excellent matte effect and thickening effect which can decrease the glossiness effectively. Besides, using silicon 

dioxide powder into coating can improve the coating's printing image and quality. When selecting silicon dioxide powder 

as matting agent, we should consider several key functions as below.

* Particle size: choosing silicon dioxide as agent should consider its particle size as well. Different particle size can make 

different matte effect. It decides if the coating can be smoother and evener.

*  Matting effective: choosing silicon dioxide in coating should also consider its matte effect. This decides the cost and the 

final appearance.

* 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.
