Gloss lacquer formula for airless spray application

This formulation is designed for a gloss lacquer intended for airless spray application. It is based on Neocryl* XK-98 acrylic glossy lacquer and includes various components to enhance the lacquer's performance and application properties.

Components and Their Functions:

1. Acrylic Copolymer Emulsion (Neocryl XK-98)*
   • Function: Acts as the binder, providing adhesion and forming a glossy film upon drying.
2. Alkaline (pHLEX™ 400)
   • Function: Serves as a neutralizing agent to adjust the pH to 8.5, ensuring stability and optimal performance of the formulation.
3. Co-solvent (Butyldiglycol)
   • Function: Functions as a coalescing agent, aiding in the film formation process by promoting the merging of polymer particles.
4. Non-ionic Synthetic Associative Thickener (NSAT) (Aquaflow™ NMS-450E)
   • Function: Acts as a rheology modifier, adjusting the viscosity and flow properties of the lacquer for better application.
5. Non-ionic Synthetic Associative Thickener (NSAT) (Aquaflow™ XLS-530E)
   • Function: Another rheology modifier to further enhance the viscosity and application characteristics.
6. Blend of Silicones and Surfactants (Drewplus™ TS-4481)
   • Function: Serves as a foam control agent, reducing foam during application to ensure a smooth finish.

Properties:

• Viscosity (Brookfield 6/4): 1600 mPa·s
• Viscosity (Brookfield 60/4): > 10000 mPa·s
• Viscosity (ICI): 140 mPa·s
• Leveling (Leneta): 7 (on a scale of 1-10, with 10 being the best)
• Sag Resistance: 600 microns
• pH: 8.5

Preparation Procedure:

• Mix the components thoroughly, adjusting the pH to 8.5 using pHLEX™ 400.
• Ensure proper dispersion of the thickeners and other additives to achieve the desired viscosity and application properties.

This formulation is tailored for achieving a high-gloss finish with excellent leveling and sag resistance, optimized for application via airless spray methods.
