Pigment Preparations
Choosing the right pigment dispersion can make or break the performance of a water-based paint, coating, or coloring system. Sudarshan's Sudafine range of pigment preparations is built specifically for this purpose — offering concentrated, easy-to-use, water-friendly color pastes that blend seamlessly into a wide variety of aqueous systems.
What Is Sudafine?
Sudafine pigment dispersions are hydrophilic pigment pastes designed for water-based applications:
- Highly concentrated and readily pourable
- Hydrophilic in nature, naturally compatible with water-based systems
- Formulated with non-ionic/anionic wetting and dispersing agents for stable dispersion
- Mix readily with aqueous bases to form stable paint
- Miscible with one another in any ratio, allowing flexible shade-matching
- Operate within a pH range of 6–9
- Fully APEO-free
Where Sudafine Is Used
- Water-borne paints
- Water-borne paints for coir products
- Artist water colors
- Chalks
- Paper and cardboard coloring
- Latex
- Soap
The Sudafine Shade Range
The portfolio spans yellows, oranges, reds, violet, blues, green, and black — each with a specific balance of shade, opacity, tinting strength, and fastness for interior or exterior use.

Choosing the Right Shade
- Higher pigment concentration generally means more color strength per unit added — useful for cost-in-use optimization.
- Light and weather fastness ratings (typically shown as two numbers, e.g., "8/8") indicate performance for full-shade and reduced-shade applications respectively — higher is better for long-term exterior durability.
- Products explicitly marked "suitable for exterior application" are the better choice for facades and outdoor coatings, while others are optimized for cost-effective interior use.
- Since all Sudafine pastes are miscible in any ratio, custom shades (like purples from Violet 41, or warm tones by blending reds and yellows) can be developed easily by combining products from this range.
