In the field of color inkjet paper and digital imaging media, the trade-off between coating ink absorption, image clarity, and drying speed has long been a core challenge limiting product quality upgrades. Traditional coating materials often compromise—fast ink absorption sacrifices clarity, while good color fixation extends drying time. Today, we present a professional solution specifically designed for inkjet printing media: IOTA Inkjet Paper Silica Sol (Model DM30) . With its high-purity, low-viscosity, and strong-adhesion nano-silica particles, it injects a new performance dimension of “fast ink absorption, accurate color rendering, and rapid drying” into your coating systems.

High-Purity Nano Silica, Coating Performance Multiplier
IOTA DM30 Silica Sol, with SiO₂ content of 30±1% and density of 1.19-1.21 g/cm³, features high-purity nano-silica particles as its active ingredient. Its low viscosity (≤10 mPa·S) ensures easy dispersion and excellent leveling in coating formulations, enabling uniform application on base paper to form a dense, porous ink-receptive layer. This structure rapidly absorbs ink solvents while firmly fixing colorants on the coating surface, delivering precise color reproduction, sharp image edges, and no bleeding or color smearing in print quality.

Alkaline-Stabilized System, Enhanced Compatibility
The product’s pH value of 9.5-10.5 ensures a mild alkaline environment that offers good compatibility with commonly used binders in inkjet coating formulations, such as polyvinyl alcohol (PVA) and polyvinyl acetate. This allows direct use without complex formulation adjustments. Meanwhile, the alkaline environment effectively inhibits microbial growth, and with a shelf life of ≥12 months, product stability is time-tested and reliable.

Accelerated Drying, Production Efficiency Leap
The high specific surface area and porous structure of nano-silica endow the coating with excellent fast ink absorption and instant drying capabilities, significantly reducing post-print waiting time and improving production line throughput. Additionally, the incorporation of inorganic silica particles provides the coating with good anti-blocking properties and water resistance, ensuring that finished prints do not stick or fade during stacking and long-term storage.

From glossy photo paper, matte inkjet paper, and RC photo paper, to digital printing coated paper and advertising inkjet media—IOTA Inkjet Paper Silica Sol, with its product philosophy of “clarity and speed in one,” helps you build more competitive digital printing coating products. Choose IOTA—choose the precision of nano-silica to capture the color essence of every ink droplet.
