Feature:
For gravure ink applications, a high-grade SiO2 Matting Agent needs to fulfill specific requirements to ensure optimal
performance. Here are some key considerations when selecting a matting agent for gravure ink:
Matting Efficiency: Look for a matting agent that provides the desired level of matte finish suitable for gravure ink
applications. The matting efficiency should be adjustable to achieve the desired gloss reduction while maintaining print
clarity and definition.
Particle Size and Distribution: Choose a matting agent with a narrow particle size distribution and fine particle size. Fine
particles tend to provide smoother matte finishes, while uniform distribution ensures consistent matting across the printed
surface.
Transparency: Ensure that the matting agent maintains the transparency and clarity of the gravure ink. The matte finish
should not introduce haze or cloudiness, preserving the optical properties and color fidelity of the printed image.
Surface Treatment: Select a matting agent that is surface-treated to improve dispersion and compatibility with the gravure ink formulation. Surface treatment helps prevent agglomeration, improve stability, and enhance handling properties during ink
manufacturing and printing.
Compatibility: Verify that the matting agent is compatible with other components of the gravure ink formulation, including binders, solvents, pigments, and additives. Compatibility testing is essential to ensure that the matting agent does not adversely affect
ink stability, rheology, or print performance.
Rheological Properties: Choose a matting agent that does not significantly alter the viscosity or flow behavior of the gravure ink.
The ink should maintain suitable rheological properties for efficient printing, coating, and drying processes without compromising
print quality or adhesion.
Adhesion: Ensure that the matting agent does not compromise the adhesion of the gravure ink to the substrate. The printed image should adhere firmly to various substrates, including paper, plastic, and metal, without flaking, cracking, or delamination.
Durability: Consider matting agents that enhance the durability and scratch resistance of the printed image. The matte finish should remain intact under handling, abrasion, and exposure to environmental factors, ensuring long-lasting performance and visual appeal.
Examples of high-grade SiO2 matting agents suitable for gravure ink applications may include products from suppliers like Evonik Industries, Wacker Chemie AG, and Cabot Corporation. Consult with these suppliers to find a matting agent that meets your specific requirements for matting efficiency, transparency, compatibility, and durability in gravure ink formulations. Additionally, conduct
thorough testing to evaluate the performance and suitability of the selected matting agent in your gravure ink application.
