What factors are related to leveling? According to the paton formula for leveling, leveling time is directly proportional to viscosity, and the higher the viscosity of the coating system, the more difficult leveling will be. Paton also stated that the leveling time is inversely proportional to the cube of the film thickness, and the thicker the film thickness, the easier it is to level.
The leveling of this thin coating will be relatively more difficult. The Paton formula states that the leveling time is inversely proportional to the surface tension of the paint film, and not necessarily the lower the surface tension, the better the leveling. Leveling is also closely related to the formula of the resin and the distribution of molecular weight
For example, acrylic resin and styrene acrylic resin have better leveling performance than pure acrylic resin. Generally speaking, the larger the molecular weight, the more difficult it is to level it.
Leveling is also closely related to the evaporation gradient of the solvent. The solvent evaporates too quickly, which can also have adverse effects on the convection bottle.
The state of the slurry of leveling and dispersing colorants has a significant impact. If a color paste is not well dispersed, it will be difficult to level the entire system in a flocculent or semi flocculent state. The state of flocculation will have a very positive impact on Liu Ping.
It is related to the rheological properties of the system. For example, water-based coatings and high shear thickeners have a very positive impact on leveling. Low shear thickeners can cause pseudoplasticity and promote denaturation. Leveling is very unfavorable, and leveling will be relatively more difficult.
