Feature
When selecting a dry chemical powder silica dioxide agent for ink formulations, it's essential to consider several
factors to ensure it meets your specific requirements. Here are some considerations:
Particle Size and Distribution: The particle size and distribution of the silica dioxide powder can impact its
performance in ink formulations. Finely ground particles tend to provide better rheological properties and dispersion
within the ink.
Surface Treatment: Some silica dioxide powders are surface-treated to improve their compatibility with ink formulations,
enhance dispersibility, and reduce dusting. Surface treatment can also influence the ink's viscosity and flow properties.
Rheology Modification: Silica dioxide powders are often used in ink formulations as rheology modifiers to control viscosity,
thixotropy, and flow behavior. Choose a powder that can effectively adjust the ink's viscosity to suit your printing process and
substrate requirements.
Matting Effect: Silica dioxide powders can act as matting agents in ink formulations to reduce gloss and create matte or satin
finishes. If you require a specific level of gloss reduction, select a powder with the appropriate matting efficiency.
Adhesion and Scratch Resistance: Silica dioxide additives can improve the adhesion of ink to various substrates and enhance
scratch resistance, especially in applications where the printed material may be subjected to handling or abrasion.
Color Development: Silica dioxide powders should be compatible with the pigments and dyes used in the ink formulation to
ensure proper color development and stability.
Compatibility: Ensure that the silica dioxide powder is compatible with other components of the ink formulation, including
binders, solvents, and additives. Compatibility testing may be necessary to verify performance and stability.
Supplier Reputation: Choose a reputable supplier known for providing high-quality silica dioxide powders and technical support.
Supplier expertise can help you select the most suitable powder for your ink formulation and offer guidance on formulation and
application techniques.
Examples of reputable manufacturers of silica dioxide powders for ink applications include Cabot Corporation, Evonik Industries,
and Wacker Chemie AG. Consulting with these suppliers and reviewing technical data sheets can help you identify the best silica
dioxide powder for your ink formulation needs.
