JSY‑RD200 is a semi‑transparent grade synthetic hectorite magnesium lithium silicate designed as a high‑performance thixotropic agent for waterborne industrial coatings. It provides effective anti‑sagging and anti‑settling performance, improving pigment suspension, leveling and storage stability. Its semi‑transparent nature ensures minimal influence on coating clarity and color development. Suitable for a wide range of waterborne industrial coating systems.

Product Detail

Product Overview

JSY‑RD200 is a semi‑transparent synthetic hectorite magnesium lithium silicate engineered as a premium thixotropic rheology modifier for waterborne industrial coatings. As a synthetic layered silicate, it hydrates and disperses in water to form a transparent thixotropic gel network, delivering efficient thickening, anti‑sagging and anti‑settling properties. Its semi‑transparent grade formulation ensures that the additive has minimal impact on the clarity, gloss and color of the finished coating. The product is free of natural impurities and offers consistent batch‑to‑batch performance for reliable industrial production.
