Organoclay SG-58
Advanced Bentonite Thickener for Solvent-Free Epoxy Tile Grout
A revolutionary organoclay rheological additive engineered for systems with low to highly polar solvents. SG-58 delivers superior anti-sag performance and supports high filler loading in demanding solvent-free epoxy formulations -- with no pre-gel or polar activator needed.
Built for Solvent-Free Epoxy Tile Grout Formulations
SG-58 addresses the two most critical challenges in solvent-free epoxy tile grout: preventing sag on vertical surfaces and enabling high filler loading without sacrificing workability.
Superior Anti-Sag Performance
SG-58 builds a robust thixotropic network that prevents grout from sagging on vertical tile joints, ensuring precise placement and a clean finish even under gravity.
High Filler Loading Support
Enables incorporation of high levels of mineral fillers (silica sand, calcium carbonate, pigments) without phase separation or excessive viscosity increase, maintaining pumpability.
No Polar Activator Needed
Unlike conventional organoclays, SG-58 activates directly in epoxy resin systems without requiring methanol, propylene carbonate, or other polar activators -- simplifying your process.
Easy to Use & Handle
More dense and less dusty than standard organoclays. Can be added directly as powder at any point in the production procedure, reducing handling complexity and workplace dust exposure.
Cost-Effective Fumed Silica Replacement
SG-58 usage levels are 30-50% less than fumed silica to achieve equivalent rheological performance, delivering significant cost savings in high-volume tile grout production.
Long-Term Viscosity Stability
Maintains consistent rheological properties throughout the shelf life of the formulated grout product, preventing settling, syneresis, and phase separation in storage.

Usage Guidelines for Epoxy Tile Grout
Recommended Dosage
Typical addition level in paint and coating systems: 0.2% - 0.7% by weight.
Exact dosage varies by resin system, filler loading, and target viscosity profile. For solvent-free epoxy tile grout with high filler content, higher end of range is recommended. Conduct formulation trials to optimize.
Addition Method
- Add SG-58 directly as powder -- no pre-gel or polar activator required.
- Incorporate at any point in the epoxy resin mixing procedure.
- Disperse under high shear mixing for optimal rheological activation.
- Add fillers (silica sand, pigments) after SG-58 dispersion for best anti-sag results.
