High‑Purity Lithium Magnesium Silicate Powder, CAS 67142‑95‑4. This synthetic hectorite is produced by hydrothermal synthesis, deep purification and spray‑drying. Low content of heavy‑metal and insoluble residues ensures high clarity after aqueous exfoliation. It functions as a water‑soluble inorganic rheology modifier, providing thixotropy, anti‑sagging and suspension stabilization for premium water‑based coatings, printing inks and transparent optical gel systems.

Product Detail

Product Detail PageHigh‑Purity Lithium Magnesium Silicate Powder CAS 67142‑95‑4, Clear Water‑Soluble Rheology Modifier for Premium Coating Ink & Optical GelThis high‑purity lithium magnesium silicate powder is manufactured via controlled hydrothermal crystallization of refined inorganic raw materials, followed by multi‑stage filtration, ion‑removal purification and spray‑drying. Rigorous quality control minimizes residual insoluble grit, colored impurities and heavy‑metal traces. Different from natural hectorite, this synthetic layered silicate possesses consistent platelet dimension, predictable hydration speed and outstanding batch‑to‑batch reproducibility, which meets strict purity requirements for premium coating, high‑grade ink and transparent optical gel applications.

When dispersed into aqueous systems under high‑speed agitation, the powder hydrates and exfoliates into discrete nanoscale silicate platelets. These nanosheets build a reversible three‑dimensional colloidal network throughout the liquid phase. At static state, the network raises the base viscosity of the liquid system to realize excellent anti‑sagging and anti‑sedimentation performance. It suspends fine pigments, functional fillers and luminescent particles inside water‑based premium coatings and printing inks, preventing pigment settling during long‑term storage. Under shear generated during spraying, roller‑coating or printing, the colloidal network breaks, system viscosity declines sharply to improve fluidity and leveling behavior. Once mechanical shear disappears, the gel‑network reconstructs quickly to restrain sagging on vertical coated substrates.

For optical gel formulations, the ultra‑low residual impurity level is essential. Complete exfoliation yields highly transparent colloidal systems without visible haze or light‑scattering speckles. It stabilizes the rheological property of optical gel, avoids fluid dripping and maintains uniform thickness of optical gel layers. The product demonstrates good compatibility with water‑based resins, polyols and many non‑ionic surfactants. It can be combined with organic associative thickeners to tailor the thixotropic curve of final coating, ink and optical gel formulas.

During formulation processing, pre‑dispersion and sufficient hydration under high‑speed stirring are required to eliminate powder agglomerates. Excessive electrolyte dosage should be restricted, since high ionic concentration suppresses full exfoliation of silicate nanosheets, resulting in reduced gel strength and unwanted hazing, which impairs the clarity of optical gel and premium transparent coatings.

This lithium magnesium silicate powder shall be stored inside hermetically sealed, dry containers. Moisture absorption will cause caking and hinder complete hydration and exfoliation. In batching and material‑handling procedures, cross‑contamination with lower‑purity industrial‑grade synthetic hectorite must be prevented. Foreign coarse grit contaminants will generate light‑scattering defects in optical gel and visible specks in high‑grade coatings and inks. This high‑purity synthetic hectorite is a high‑performance clear water‑soluble inorganic rheology modifier formulated for premium water‑based coating, printing ink and optical‑gel systems.
