OPTIGEL‑WX Equivalent Water‑Activated Montmorillonite (CAS 68953‑58‑2) is specially processed inorganic layered silicate powder designed as direct alternative to OPTIGEL‑WX, mainly used for architectural latex paint systems. When mixed under moderate high‑shear conditions in aqueous media, the silicate layers hydrate and exfoliate to build a reversible three‑dimensional thixotropic gel network. At static storage, the network effectively suspends titanium dioxide and mineral extenders, preventing

Product Detail

Product Overview

OPTIGEL‑WX Equivalent Water‑Activated Montmorillonite, CAS 68953‑58‑2, is refined natural montmorillonite with special surface treatment, serving as high‑performance inorganic rheology substitute for OPTIGEL‑WX. This rheology‑modifying powder is optimized for architectural interior and exterior latex paint formulations. Different from solvent‑grade organophilic bentonite, this water‑activated montmorillonite develops rheological property via hydration‑driven exfoliation in water phase, without additional polar activator. Exfoliated silicate platelets construct a reversible three‑dimensional colloidal thixotropic network inside latex‑water matrix. Under static storage, the network holds titanium dioxide, calcium carbonate and other mineral extenders in stable suspension and suppresses hard sediment cake. During roller coating or brushing, mechanical shear disrupts the colloidal network, lowering paint viscosity and enabling good flow‑out and leveling of wet paint film. Once construction is finished, the thixotropic network rebuilds quickly and effectively resists sagging and runs on vertical wall substrates. This inorganic clay shows excellent compatibility with various acrylic and styrene‑acrylic latex emulsions as well as common coating additives. It exerts only minor adverse effects on scrub resistance, matte finish and colour‑developing performance of cured paint film. Consistent batch‑to‑batch quality guarantees stable production of large‑volume architectural latex paints.

Key Features

‑ Water‑activated montmorillonite, functional equivalent to OPTIGEL‑WX for architectural latex waterborne paint ‑ Hydration‑triggered platelet exfoliation in aqueous system, no polar activator required ‑ Superior anti‑settling performance for titanium dioxide and mineral fillers during long‑term latex paint storage ‑ Reliable anti‑sag property on vertical wall surfaces for interior‑exterior architectural coating construction ‑ Typical shear‑thinning thixotropic behaviour, balancing storage suspension stability and on‑site wet‑film leveling ‑ Good compatibility with acrylic and styrene‑acrylic latex emulsions, low interference on scrub‑resistance and matte finish ‑ Fine free‑flowing off‑white powder, suitable for feeding on large‑scale latex paint production lines ‑ Stable rheological consistency for mass‑production of interior and exterior architectural water‑based wall paints

Technical Specifications

‑ Product Name: OPTIGEL‑WX Equivalent Water‑Activated Montmorillonite ‑ CAS Number: 68953‑58‑2 ‑ Appearance: Off‑white fine powder ‑ Moisture: ≤3.8 % ‑ Loss on ignition: 10.0‑16.0 % ‑ Fineness (325 mesh residue): ≤2.0 % ‑ Bulk density: 0.24‑0.35 g/cm³

Application Scenarios

‑ Interior matte architectural latex wall paints ‑ Exterior weather‑resistant waterborne latex coatings ‑ High‑filler architectural paint formulations prone to pigment sedimentation ‑ Water‑based decorative wall coatings requiring balanced anti‑sag and leveling ‑ Inorganic rheology‑modifying additive for architectural latex paint manufacturing

Usage Recommendation

‑ Typical dosage range: 0.3‑1.4 % based on total paint formulation weight ‑ Add montmorillonite powder into grinding water phase under moderate high‑shear mixing at the pigment‑grinding stage before latex emulsion addition ‑ Sufficient hydration and dispersion time is essential to develop target thixotropy; inadequate hydration will lead to poor anti‑settling result ‑ Conduct full laboratory pre‑evaluation covering viscosity, anti‑sag, leveling, storage stability, scrub resistance and colour acceptance before mass‑scale paint production ‑ Avoid over‑dosage; excessive addition may increase paint viscosity significantly and impair wet‑film leveling performance

Package & Storage

‑ Standard packing: 25kg kraft paper bag with inner PE liner ‑ Store in cool, dry and ventilated warehouse; protect powder from moisture absorption and heavy compression ‑ Tightly seal opened bags to prevent moisture ingress ‑ Shelf life: 12 months under recommended storage conditions

Safety Notes

‑ Avoid dust generation and inhalation during material handling; wear suitable dust mask and safety goggles. ‑ Prevent direct skin contact; chemical‑resistant gloves are required for operation. ‑ Keep away from open flame and high‑temperature heat sources. ‑ Please refer to SDS document for comprehensive guidance on handling, transportation and emergency disposal.
