Paint Industry
The temperature requirements for cooling in paint manufacturing vary depending on the type of paint (e.g., water-based, oil-based, latex), the specific resins, solvents, and pigments used, as well as the equipment and process steps involved. Here’s a general guide for the cooling requirements and temperature ranges in the paint-making process:
Preventing Overheating During High-Shear Mixing or Milling
CST’s dry cooling system is ideal for maintaining the controlled temperature range of 40–50°C (104–122°F) during high-shear mixing or milling in paint manufacturing without the need for chillers. By using ambient air to dissipate heat through finned coils, it effectively manages process temperatures to prevent pigment degradation and ensure binder stability. This stability is crucial for maintaining formulation integrity, preventing changes in viscosity, and reducing component separation. Additionally, CST's system is a sustainable, cost-effective solution that aligns with industry goals for energy efficiency and reduced environmental impact, eliminating the high operational costs associated with chilled water systems.
Setting Viscosity and Stabilizing After Dispersion
A typical temperature range of 25–30°C (77–86°F) is essential after pigment dispersion, as cooling the mix to near ambient levels helps achieve the desired viscosity and stabilize the paint for consistent texture and flow. This temperature control is especially important before moving to subsequent processing stages or packaging. CST’s adiabatic cooling systems efficiently provide this cooling, leveraging evaporative cooling to maintain optimal conditions without the high energy demands of traditional chillers. This approach ensures both product quality and energy efficiency in the manufacturing process.
Improving Shelf Stability Post-Heating
A typical temperature range of 20–25°C (68–77°F), achieved through gradual cooling to ambient or slightly below, is crucial after any heating processes in paint manufacturing. This controlled cooling helps prevent phase separation and reduces the risk of settling, maintaining the paint's stability and quality. Keeping the mixture at ambient or slightly lower temperatures during packaging also supports long-term shelf stability. CST’s adiabatic chillers efficiently achieve these temperatures, providing reliable cooling without the need for high-energy, conventional chillers, thus ensuring quality while optimizing energy use.
