Description

Laponite XLS is a synthetic, layered silicate clay belonging to the smectite group, specifically designed for its superior rheological and thixotropic properties. This high-purity material is essential for creating stable, shear-thinning gels and suspensions in aqueous systems. It is a critical additive for formulators in the personal care, coatings, and construction industries who require precise control over product viscosity, stability, and application behavior.

Application

• Personal Care & Cosmetics: Acts as a primary or secondary rheology modifier and suspending agent in creams, lotions, sunscreens, and decorative cosmetics to prevent settling and provide elegant texture.
• Paints & Coatings: Used as an anti-settling and anti-sagging agent in water-based paints, providing excellent sag resistance and pigment suspension without affecting gloss.
• Adhesives & Sealants: Imparts thixotropy and body to water-based adhesives, mastics, and grouts, improving application properties and preventing slump.
• Construction Chemicals: Serves as a thickener and water retention aid in cement-based products, tile adhesives, and spray plasters.
• Household & I&I Cleaners: Provides viscosity control and stabilization in liquid soaps, hard surface cleaners, and toilet blocks.
• Agrochemicals: Used as a suspending agent and viscosity modifier in suspension concentrates (SC) and capsule suspensions (CS) for improved stability and handling.
• Ceramics: Acts as a binder and rheology modifier in ceramic glazes and casting slips.
• Drilling Fluids: Functions as a viscosifier and fluid loss control additive in water-based drilling muds.

Quality Control

Our Laponite XLS is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Quality is verified through a series of tests including rheological performance, particle size distribution, and chemical composition analysis. Certificates of Analysis (COA) documenting key specifications are available upon request for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent caking and degradation due to moisture absorption.
