JSY‑RD200 is a semi‑transparent synthetic hectorite magnesium lithium silicate powder designed as a high‑performance rheology modifier. With 88% light transmittance, it delivers excellent thickening, suspension and thixotropic properties while maintaining clarity in formulations. It is widely used in architectural latex paint to improve sag resistance and pigment suspension, and in oral care products such as toothpaste to stabilize texture and enhance mouthfeel. CAS 37220‑90‑9.

Product Detail

Product Overview

JSY‑RD200 is a synthetic hectorite magnesium lithium silicate powder engineered as a premium rheology modifier for industrial and personal care formulations. As a synthetic layered silicate, it disperses in water to form a transparent thixotropic gel, providing efficient thickening, suspension and anti‑sag performance. Its 88% light transmittance ensures minimal impact on the clarity and color of finished products. The product is free of natural impurities and offers batch‑to‑batch consistency, making it a reliable choice for architectural latex paint and oral care applications.

Usage Recommendation

Typical dosage: 0.2%–1.5% in latex paint; 0.5%–2.0% in oral care formulations
Add powder slowly under high‑shear mixing to ensure full hydration and dispersion
Pre‑disperse in water before incorporating into the formulation for best results
Adjust dosage based on desired viscosity, rheology profile and system compatibility
Full hydration typically requires 15–30 minutes of high‑speed mixing
