Organoclay for Pigment and Filler Suspension
Overview of Organoclay Suspension Technology
Organoclay, also known as rheology modifier, organophilic clay, or modified bentonite, is a high-efficiency rheological additive specifically engineered for superior pigment and filler suspension in various formulation systems. As a leading manufacturer with over two decades of expertise, CAMP-SHINNING produces premium organoclay products that serve as essential anti-settling agents, anti-sagging agents, and thixotropic agents across multiple industries.
Our organoclay products are modified from high-quality sodium bentonite powder through advanced wet and dry processes, resulting in materials that provide exceptional suspension properties, preventing pigment settling and filler sedimentation in coatings, inks, adhesives, and other formulations.
Key Suspension Properties
Anti-Settling Performance
Prevents pigment and filler sedimentation during storage, maintaining uniform dispersion throughout the product shelf life
High Thixotropy
Provides shear-thinning behavior, ensuring easy application while maintaining suspension at rest
Anti-Sagging Control
Prevents vertical sagging on applied surfaces, critical for coating applications on walls and vertical substrates
Viscosity Control
Offers precise rheology modification for optimal viscosity profiles across different shear rates

Applications in Major Industries
Coatings Industry
Organoclay serves as a critical suspending agent in various coating formulations:
- Solvent-based automotive coatings - prevents metallic pigment settling
- Marine coatings - maintains anti-fouling pigment suspension
- Industrial coatings - ensures uniform filler distribution
- Wood coatings - provides anti-sagging properties on vertical surfaces
- Anti-corrosion coatings - suspends heavy corrosion inhibitor pigments
- High-temperature coatings - maintains thermal barrier pigment suspension
Ink Manufacturing
Essential for pigment suspension in multiple ink types:
- Gravure inks - prevents pigment settling during high-speed printing
- Flexographic inks - maintains color consistency
- Screen printing inks - provides optimal thixotropy for sharp prints
- UV-curable inks - suspends photoinitiators and pigments
- Packaging inks - ensures long-term storage stability
- Digital printing inks - maintains nano-pigment dispersion
Adhesives & Sealants
Provides suspension and anti-settling properties:
- Solvent-based adhesives - suspends fillers and reinforcing agents
- Polyurethane sealants - prevents pigment separation
- Construction adhesives - maintains filler distribution
- Automotive adhesives - provides anti-sagging on vertical joints
Cosmetics
Ensures uniform pigment and active ingredient suspension:
- Foundations and makeup - maintains color pigment suspension
- Sunscreen formulations - suspends UV-blocking particles
- Nail polishes - prevents pigment settling
- Creams and lotions - stabilizes active ingredient dispersion

Usage Guidelines for Optimal Suspension
General Addition Procedure
- Pre-dispersion preparation: Add organoclay to the solvent or resin phase under moderate agitation before adding pigments and fillers
- Dosage: Typical addition level is 0.5-2.5% of total formulation weight (adjust based on specific suspension requirements)
- Polar activator: Add polar activator (typically 30-40% of organoclay weight) such as methanol, ethanol, or propylene carbonate
- High-shear mixing: Apply high-shear dispersion for 15-30 minutes to achieve full activation
- Pigment addition: Add pigments and fillers after organoclay gel formation for optimal suspension
- Final adjustment: Additional organoclay can be added post-formulation to correct rheology if needed
Optimization Tips for Maximum Suspension Efficiency
- Use high-speed dispersers (1500-3000 rpm) for better gel development and pigment wetting
- Temperature control: Maintain 25-35°C during dispersion for optimal gel formation
- Match organoclay polarity to solvent system for maximum efficiency
- For water-based systems, use CP-EW, CP-WBS, or CP-EWS grades specifically designed for aqueous suspension
- Extend mixing time for heavily pigmented or high-filler-content formulations
