Professional Silica Powder For Soft Texture Paper

Characteristics

When selecting a professional silica powder for achieving a soft texture in paper coatings, you'll want to focus on several key characteristics to ensure optimal performance and desired tactile qualities. Here's what to consider:

Surface Modification: Surface-treated silica particles can enhance compatibility with the paper coating binder and improve 

dispersibility, adhesion, and durability of the coating. Surface modification can also influence properties such as softness, 

smoothness, and printability of the paper.

Matting Efficiency: If a matte appearance is desired along with a soft texture, consider the matting efficiency of the silica powder. 

Higher matting efficiency allows for the reduction of glossiness while maintaining the soft feel of the paper surface.

Softness Enhancement: Look for silica powder additives specifically designed to enhance softness in paper coatings. These 

additives typically have surface modifications or unique particle structures that impart a gentle, velvety texture to the paper surface.

Transparency: Ensure that the silica powder maintains the transparency of the coating to preserve the brightness and clarity of 

printed or coated materials. Transparency is crucial for maintaining the visual appeal of the paper while achieving the desired soft 

texture.

Dispersion Stability: The silica powder should disperse easily and uniformly in the coating formulation to achieve consistent 

texture across the paper surface. Good dispersion stability prevents issues such as agglomeration or uneven coating, which 

could affect the softness and appearance of the paper.

Compatibility: Verify that the silica powder is compatible with other components in the coating formulation, including binders, 

pigments, and additives. Compatibility testing is essential to ensure that the silica powder does not negatively affect coating 

performance or stability.

Regulatory Compliance: Ensure that the silica powder 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.
