The common methods for evaluating the performance of leveling agents include:

Liquidity testing: such as the Tu-4 cup method, rotational viscometer method, etc., to measure the fluidity and spreadability of coatings.

Glossiness test: Use a glossiness meter to measure the glossiness of the coating surface, reflecting the quality of the leveling effect.

Surface flatness test: Observe the coating surface under a microscope to evaluate the presence of defects such as pinholes and orange peel lines.

Weather resistance testing: simulating exposure testing under natural environmental conditions to evaluate the leveling stability of coatings during long-term use.

The performance of leveling agents is influenced by various factors, and environmental conditions directly affect the evaporation rate and leveling effect of coatings. The types and proportions of other components such as resins, pigments, solvents, etc. can affect the effectiveness of leveling agents. Different construction methods such as spraying, brushing, and roller coating can have an impact on leveling. The water absorption and surface roughness of the substrate can also affect the wetting and leveling of the coating.

The strategies for optimizing the performance of leveling agents include:

Reasonable selection of leveling agent type: Choose the appropriate leveling agent based on the type and performance requirements of the coating.

Adjust formula ratio: Optimize the ratio of resin, pigment, solvent and other components to achieve the best leveling effect.

Improve construction technology: Optimize construction parameters such as spraying pressure, spraying distance, etc., to reduce adverse factors during the construction process.

Enhance environmental friendliness: Use environmentally friendly leveling agents to reduce pollution to the environment.

With the increasing awareness of environmental protection, countries have increasingly strict environmental requirements for leveling agents. Enterprises should choose leveling agents that meet environmental standards to ensure that their products do not pose a threat to the environment and human health during use. At the same time, close attention should be paid to updates in relevant environmental regulations, and production processes and formulas should be adjusted in a timely manner to meet market demand.
