5214 provides excellent leveling performance and anti-sag performance as well as good color paste stability. It can form micelles in the aqueous phase, so that the hydrophobic end is adsorbed with the hydrophobic structure of latex particles and surfactants, forming a three-dimensional network structure, which increases the viscosity of the system. Compared with other water-based thickeners, it has extremely comprehensive performance and has little impact on the water resistance and salt spray resistance of the paint film. Its characteristics are: anti-biodegradation, excellent anti-splash, high fullness of the coating film, uniform coating while does not affect the gloss of the paint film, and can be used in wide pH range. The thickening efficiency is affected by emulsion, PVC, solid content, etc., and it is also sensitive to surfactants, alcohol solvents and dispersants etc.
