Alkyd emulsion high gloss white top coat

This formulation is engineered to produce a high gloss white top coat with exceptional opacity, durability, and application properties. It combines various components to achieve the desired attributes, including binders, pigments, rheology modifiers, and additives for stability and performance enhancement.

Components and Their Functions:

1. Water
   • Function: Acts as a vehicle for other components, aiding in dispersion and application.
2. Dispersing Agent (Block Co-polymer Disperbyk 190)
   • Function: Facilitates the dispersion of pigments and fillers, ensuring uniform color development.
3. Foam Control Agent (Blend of silicones and surfactants Drewplus TS-4385)
   • Function: Controls foam formation during mixing and application, contributing to a smooth finish.
4. Biocide (Nuosept BIC)
   • Function: Preservative to prevent microbial growth within the paint.
5. Co-solvent (propaan-1,2-diol Propylene Glycol)
   • Function: Enhances the solubility of other components, improving formulation stability.
6. Binder (Alkyd emulsion Uradil AZ 785-Z52)
   • Function: Forms a film that adheres to the substrate, providing adhesion and durability to the coating.
7. Dryer (Non-carboxylate iron complex Borchi OXY-coat 1101)
   • Function: Enhances drying properties, promoting faster curing of the coating.
8. Substrate Wetting Agent (Silicon based Surfactant BYK 347)
   • Function: Improves wetting of the substrate, ensuring uniform application and adhesion.
9. Surfactant (Phosphate ester Dextrol OC-180HS)
   • Function: Enhances dispersion and stability of the formulation.
10. NSAT Rheology Modifiers (Aquaflow XLS-530E and Aquaflow NMS-450E)
    • Function: Adjusts viscosity and flow behavior, improving application properties.

Viscosity Properties:

• Brookfield (20/4): 3600 mPa·s
• Stormer: 90 KU
• ICI: 300 mPa·s
• Leveling (Leneta): 10 (1-10; 10=Best)
• Sag Resistance: 300 micron
• Gloss (60°): 100 GU

(All viscosities are measured at 25°C)
