In solvent-based coating formulations, selecting the right anti-settling and thixotropic agent is essential for balancing storage stability with a high-quality surface finish. Ruike Chemical offers three distinct solutions, each designed for specific performance requirements.

1. Core Technical Specifications

2. Distinct Functional Advantages

6900-20X: The Specialist for Thixotropy and Anti-Sagging

• Structural Body: Forms a powerful internal network that provides exceptional anti-sagging, anti-settling, and thickening effects.

  
  

• Broad Compatibility: Works with a wide range of resins (Epoxy, PU, Acrylic) without negatively impacting gloss.

  
  

• Ease of Activation: Operates across a wide temperature range ($25^{\circ}\text{C} – 60^{\circ}\text{C}$) without requiring heat for activation.

  
  

201P: The Solution for Viscosity-Neutral Anti-Settling

• Stable Rheology: Provides strong anti-settling performance without significantly increasing the system's viscosity.

  
  

• Surface Aesthetics: Has no significant impact on yellowing resistance or drying speed and can improve the tactile feel of the film.

  
  

• Convenient Processing: Can be used as a post-additive without the need for grinding, ideal for sensitive color pastes.

  
  

EVA Wax Paste: The Economical Choice for Metallic Orientation

• Flake Alignment: Specifically engineered for superior orientation of aluminum (silver) pigments, preventing matting while maintaining flow.

  
  

• Thermal Stability: Offers good heat resistance and anti-hardening properties without thickening the system.

  
  

• Application: Highly suitable for 2-component automotive and industrial metallic paints where cost-efficiency is a priority.

  
  

3. Application-Based Selection Guide

• For Vertical Surfaces & Heavy Fillers: Choose 6900-20X

• Best for preventing the settling of heavy materials like glass powder or fillers.

  
  

• Provides the necessary thixotropy to prevent drips on vertical application.

  
  

• For Precise Viscosity Control: Choose 201P

• Best for automotive or wood coatings where the existing viscosity must remain unchanged.

  
  

• For Metallic Sparkle & Bulk Efficiency: Choose EVA Wax Paste

• Best for high-volume industrial metallic coatings where silver powder alignment is critical.

  
  

4. Processing Recommendations

1. Shear Requirements: All three additives require high-speed dispersion to be fully effective.

   
   

2. Temperature Management: For 6900-20X, ensure the temperature stays below $60^{\circ}\text{C}$ during the dispersion process to maintain stability.

   
   

3. Addition Order: When using 201P in aluminum paints, it is essential to disperse the wax into the resin first before incorporating the aluminum paste.
