Lithium Magnesium Silicate Thickener, opaque synthetic hectorite, CAS 67142‑95‑4. It is manufactured through hydrothermal synthesis, basic purification and spray‑drying. When dispersed in aqueous media, the layered silicate exfoliates into nanoscale silicate platelets and builds robust reversible thixotropic colloidal networks. This cost‑effective inorganic rheology additive is designed for pesticide SC formulations and construction‑grade water‑based coatings to restrain solid sedimentation, con

Product Detail PageLithium Magnesium Silicate Thickener Opaque CAS 67142‑95‑4, Cost‑Effective Rheology Modifier for Pesticide SC & Construction CoatingThis opaque‑grade synthetic hectorite thickener is produced by hydrothermal crystallization of inorganic raw mineral feedstock, basic filtration purification and spray‑drying. Compared with medium‑clarity and high‑transparency grades, this opaque variant contains a higher content of trace micro‑impurities. After full hydration in water, the resultant slurry exhibits obvious opaque milky appearance. It maintains stable platelet dimension and consistent gelling capacity from batch to batch, making it suitable for cost‑sensitive industrial formulations where optical transparency is not a required performance indicator.

When subjected to high‑speed dispersion in aqueous systems, the free‑flowing white powder gradually hydrates and exfoliates into thin silicate nanosheets. These nanosheets interconnect to construct a three‑dimensional reversible colloidal network within the aqueous phase. Under static storage conditions, the network raises static viscosity of the slurry system. For pesticide suspension concentrate (SC), it suspends insoluble solid pesticide active particles, slows down gravity‑driven sedimentation and prevents the formation of hard sediment cake at the bottom of storage drums. For water‑based construction coatings, the network stabilizes heavy mineral pigments and extenders, minimizing pigment settling during warehouse storage.

Under mechanical shear generated during agitation, pumping, spraying or roller application, the internal colloidal network is disrupted, and slurry dynamic viscosity decreases significantly. This shear‑thinning characteristic improves fluidity during processing and field construction. Once external shear force disappears, the gel‑like network reconstructs rapidly, providing excellent anti‑sagging performance for vertical construction coating surfaces. For pesticide SC, fast network re‑formation also helps to suppress rapid re‑sedimentation after tank‑mixing and field spraying.

This opaque synthetic hectorite shows good compatibility with common formulation auxiliaries including pesticide dispersants, water‑based acrylic emulsions and construction coating additives. It can be combined with organic thickeners such as xanthan gum and cellulosic derivatives to fine‑tune overall thixotropic curve of finished pesticide SC and construction coating. Due to its intrinsic opaque milky slurry appearance, this grade shall not be used for cosmetic, skincare or high‑clarity optical gel systems.

During formulation processing, sufficient pre‑hydration under high‑speed stirring is mandatory before mixing with other functional components. High‑electrolyte loading should be limited. Excessive salt concentration will hinder complete exfoliation of silicate nanosheets, reduce gel strength and weaken anti‑sedimentation performance of finished slurries.

This opaque lithium magnesium silicate thickener needs hermetically sealed dry storage. Moisture absorption will trigger powder caking, which leads to incomplete hydration and loss of thixotropic efficiency. In material transfer and batching operations, cross‑contamination with high‑transparency cosmetic‑grade synthetic hectorite must be strictly avoided. Contamination will cause unexpected rheological fluctuation of pesticide suspension concentrates and construction coatings. This opaque synthetic hectorite serves as a reliable, cost‑effective inorganic rheology modifier for pesticide SC and water‑based construction coating systems.
