Dimethylethanolamine (DMAE) is a water-soluble clear liquid with an amine-like odor. It is used in a variety of applications, including water-based paints. In waterborne coatings, DMAE is used as an emulsifier, dispersant and leveling agent. It helps keep the paint particles evenly dispersed in the water and prevents them from settling out. DMAE also helps improve paint flow and leveling, resulting in a smooth, even finish.

DMAE is also used in water-based paints to improve the adhesion of the paint to the substrate. It does this by forming a chemical bond between the paint and the substrate. This helps ensure that the paint adheres well to the surface and does not peel or flake easily.

Additionally, DMAE can be used to improve the durability of waterborne coatings. It does this by protecting the paint from sunlight, water and other environmental elements. This helps extend the life of the paint and keeps it looking its best for longer.

Overall, DMAE is a versatile and effective ingredient for enhancing the quality of waterborne paints. It helps to maintain the uniform dispersion of the paint, improve the fluidity and leveling of the paint, enhance the adhesion between the paint and the substrate, and protect the paint from the influence of the environment.
