GARAMITE‑1210 Equivalent Organoclay (CAS 68953‑58‑2) is mixed‑mineral surface‑modified organoclay powder developed as direct alternative to GARAMITE‑1210. It is specially engineered for low‑solvent and solvent‑free adhesive, sealant and thick‑film coating systems. Under sufficient high‑shear dispersion, silicate platelets exfoliate to build a reversible three‑dimensional thixotropic network inside resin matrix. During static storage, the network effectively suspends mineral fillers and pigments

Product Detail

Product Overview

GARAMITE‑1210 Equivalent Organoclay, CAS 68953‑58‑2, is produced from purified layered silicate via special organic surface modification, acting as premium substitute for GARAMITE‑1210. This rheology additive is optimized for low‑solvent and solvent‑free formulations including construction sealants, structural adhesives and heavy‑build thick‑film industrial coatings. Unlike traditional organo‑bentonite grades, this mixed‑mineral product achieves sufficient exfoliation of silicate platelets merely by intensive high‑shear dispersion without additional polar activator. Exfoliated silicate sheets construct a reversible three‑dimensional colloidal thixotropic network within polymer matrix. At static storage, this network keeps dense mineral fillers and colour pigments suspended steadily and inhibits compact hard sediment formation inside the container. During extrusion from cartridge, hand trowelling or airless spraying, mechanical shear force destroys the thixotropic network, lowering system viscosity to guarantee favourable extrudability, spreadability and surface wetting. Once construction operation is finished, the thixotropic network rebuilds rapidly, delivering outstanding anti‑sag and anti‑dripping performance on vertical and inclined surfaces. This organoclay exhibits good compatibility with polyurethane, epoxy, modified silane and other binder systems. It exerts only minor adverse impact on final bonding strength, elongation and outdoor weather‑resistant properties of cured sealant and coating. It maintains consistent batch‑to‑batch quality for continuous mass‑production of adhesives, sealants and heavy‑build industrial coatings.

Key Features

‑ Mixed‑mineral organoclay powder, functional equivalent to GARAMITE‑1210 for adhesives, sealants and thick‑film coatings ‑ No mandatory polar activator required; sufficient high‑shear dispersion completes silicate platelet exfoliation ‑ Excellent anti‑settling capacity for mineral fillers and pigments during long‑term storage of sealant and adhesive ‑ Superior anti‑sag and anti‑dripping property for vertical and inclined‑surface thick‑film application ‑ Distinct shear‑thinning thixotropic behaviour, balancing extrusion workability and static suspension stability ‑ Broad binder compatibility with PU, epoxy and modified‑silane polymer systems, low interference to curing and final physical performance ‑ Free‑flowing fine powder, convenient for feeding in sealant and adhesive manufacturing workshops ‑ Stable rheological consistency for large‑scale production of construction sealants, structural adhesives and heavy‑build industrial coatings

Technical Specifications

‑ Product Name: GARAMITE‑1210 Equivalent Organoclay ‑ CAS Number: 68953‑58‑2 ‑ Appearance: Light off‑white fine powder ‑ Moisture: ≤3.5 % ‑ Loss on ignition: 33.0‑41.0 % ‑ Fineness (325 mesh residue): ≤2.0 % ‑ Bulk density: 0.26‑0.36 g/cm³

Application Scenarios

‑ Solvent‑free and low‑solvent construction polyurethane and modified‑silane sealants ‑ Two‑component structural adhesives for industrial assembly ‑ Heavy‑build thick‑film solvent‑free anti‑corrosion protective coatings for steel ‑ Filled adhesive and sealant formulations loaded with mineral extenders ‑ Rheology‑modifying thickening powder for adhesive, sealant and thick‑film coating manufacturing

Usage Recommendation

‑ Typical dosage range: 0.4‑1.7 % calculated on total formulation weight ‑ Add organoclay powder into base polymer under high‑shear dispersion before incorporating mineral fillers and curing components ‑ Sufficient high‑shear mixing is critical to achieve target thixotropy; inadequate dispersion will result in insufficient thickening and poor anti‑sag performance ‑ Carry out complete laboratory pre‑tests covering viscosity, extrudability, anti‑sag property, storage stability and final cured physical properties prior to mass‑scale production ‑ Avoid excessive addition, which may lead to undesired high viscosity and deteriorate extrusion and trowelling workability

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 ‑ Keep bags tightly sealed after opening to prevent moisture ingress ‑ Shelf life: 12 months under proper 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.
