Lithium Magnesium Sodium Silicate (Hatorite® S482)
The Clear Leader
Description
Hatorite S482 is a modified synthetic magnesium lithium silicate with pronounced platelet structure.
When dispersed in water, Hatorite S482 forms a transparent, pourable liquid up to a concentration of 25% solids. In resin formulations, however, significant thixotropy and a high yield value can be incorporated.

General Information:
Due to its good dispersability, HATORTITE S482 can be used as a powder additive in high gloss and transparent waterborne products. The preparation of pumpable 20-25% pregels of Hatorite® S482 is also possible.
It must be observed, however, that during the production of a (for example) 20% pregel, the viscosity can be high at first and therefore the material should be added slowly to the water. A 20% gel, however, shows good flow properties after 1 hour.
By using HATORTITE S482, stable systems can be produced. Due to the Thixotropic characteristics of this product, the application properties are significantly improved. HATORTITE S482 prevents settling of heavy pigments or fillers. As a Thixotropic agent, HATORTITE S482 reduces sagging and allows the application of thick coatings. HATORTITE S482 can be used to thicken and stabilize emulsion paints. Depending on the requirements, between 0.5% and 4% of HATORTITE S482 should be used (based on total formulation). As a Thixotropic anti-settling agent, HATORTITE S482 can also be used in: adhesives, emulsion paints, sealants, ceramics, grinding pastes, and water reducible systems.
Hints for Practical Use:
In deionized, or very soft water, low viscosity suspensions of up to 25% Hatorite S482
can be prepared using low shear. These suspensions can be handled at low viscosity for several hours.
If only hard water is available, it should be demineralized applying the usual methods (ion exchange, polyphosphates, Zeolite, etc.). Accelerated swelling can be accomplished by heat (35-60°C), high shear mixing, addition of electrolytes or a combination of these variables.
Product Application:
HATORITE S482 must be dispersed in water before use and may be added to formulations at any point during manufacture. It is used to impart a shear sensitive structure to a wide range of waterborne formulations including DIY and industrial surface coatings, household cleaners, ceramic and agrochemical products.
Storage
Hatorite S482 is hygroscopic and should be stored under dry condition.
