Bentone High-Performance Rheological Additive for Solvent-Based Systems

Bentone 38

High-Performance Rheological Additive for Solvent-Based Systems

Description:
Bentone 38 is an organoclay-based rheological additive designed to enhance the viscosity, suspension stability, and anti-sag properties of solvent-based formulations. Widely used in coatings, sealants, inks, greases, and other industrial applications, it offers excellent thixotropic behavior and anti-settling characteristics without affecting gloss or color.

Product Details:

• INCI Name: Quaternium-90 Bentonite

• CAS Number: 68953-58-2

• Form: Fine, off-white powder

• Appearance in Use: Provides smooth, thickened texture in solvent-based systems

• Compatibility: Compatible with aromatic and aliphatic hydrocarbons, esters, ketones, and alcohols (when used with suitable activators)

• Activation Required: Yes – requires polar activator and high-shear mixing for optimal performance

Key Features:

• 🌟 Excellent thixotropy and sag resistance

• 🧪 Enhances pigment suspension and prevents settling
