Product Detail

CAS 7631-86-9 Nano Silica Sol High Solid Content for Inkjet Coating Gloss Enhancer

Product Overview

CAS 7631-86-9 High Solid Content Nano Silica Sol is water-based colloidal silica with controllable nano particle size. Nano SiO₂ particles maintain stable dispersion state in aqueous medium. When used in inkjet coating, it effectively elevates surface gloss, improves ink absorption uniformity and increases coating compactness. Meanwhile, it delivers good anti-blocking performance. It is a professional gloss enhancing additive tailored for inkjet coating formulations.

Core Features

High Solid Content: Reduce transportation cost and formula dilution impact, convenient for formula adjustment.
Excellent Gloss Enhancement: Significantly lift surface gloss of inkjet receiving coating.
Uniform Ink Absorption: Prevent ink diffusion and color bleeding, achieve clear printing effect.
Stable Dispersion: No rapid agglomeration, good compatibility with various water-based binders.
Improve Film Density: Strengthen coating structure, enhance water resistance and anti-blocking property.
Low impurity level: Less adverse influence on ink color development.

Product Specifications

Product Name: High Solid Content Nano Silica Sol

CAS No: 7631-86-9

Appearance: Translucent uniform liquid

Effective Component: Nano Silicon Dioxide

Core Functions: Gloss enhancement, ink absorption adjustment, anti-blocking
