NESCGLE APPLICATION

Modeling Drying and Curing Processes: In the paints and coatings industry, drying and curing are critical steps where solvent evaporation or chemical reactions transform a liquid paint into a solid film. These processes are inherently non-equilibrium due to time-dependent changes in composition and structure.

KEY HIGHLIGHTS

By applying NE-SCGLE theory, researchers and engineers in the paints and coatings industry can gain a deeper understanding of the dynamic processes involved during application and aging, leading to improved product performance and reliability.

Solvent Evaporation

NE-SCGLE can be used to model how solvents evaporate from the paint matrix over time, which affects drying rates and the final mechanical properties of the coating. By simulating these dynamics, manufacturers can optimize solvent compositions and environmental conditions (like humidity and temperature) for faster and more uniform drying.

Polymerization Reactions

Many coatings involve polymerization reactions that occur as solvents evaporate or under specific curing conditions. NE-SCGLE can help predict the kinetics of these reactions and their impact on film formation, allowing engineers to design formulations that achieve desired properties such as hardness, flexibility, or chemical resistance.

Phase Separation and Gelation

In some coatings, especially those with complex formulations (e.g., latex paints), phase separation or gelation can occur as the solvent evaporates. NE-SCGLE models can provide insights into these processes, helping to prevent defects like blistering or cracking by adjusting formulation parameters.

Aging and Environmental Exposure

Over time, coatings are exposed to environmental factors such as UV light, moisture, and pollutants, leading to aging effects that may alter their properties. NE-SCGLE can simulate how these external conditions influence the non-equilibrium dynamics within the coating material, aiding in the development of more durable products.
