Anti-Settling Additive for Powder Coatings: Organoclay Solutions
Understanding Settling Issues in Powder Coatings
Powder coatings face significant challenges with particle settling during storage and application. This phenomenon can lead to uneven coating thickness, poor finish quality, and reduced product performance. Anti-settling additives, particularly organoclay-based solutions, provide effective rheological control to maintain uniform particle suspension.
Settling in powder coatings can occur within hours of mixing, making immediate application or proper anti-settling additives essential for quality results.
Organoclay Anti-Settling Solutions
CAMP-SHINNING's organoclay additives provide superior anti-settling properties for powder coating formulations. These modified montmorillonite clays create a three-dimensional gel structure that prevents particle separation while maintaining application properties.

Application Guidelines and Dosage Recommendations
Incorporation Method
- Pre-blend preparation: Mix organoclay with a small portion of resin powder using a high-speed mixer for 2-3 minutes
- Gradual addition: Add the pre-blend to the main formulation during the initial mixing stage
- Dispersion: Mix for 5-8 minutes at medium speed to ensure uniform distribution
- Final blending: Add remaining components and mix for additional 10-15 minutes
- Quality check: Verify homogeneity through visual inspection and particle size analysis
