Coating leveling agent-small dosage has great effect

Coating leveling refers to the process in which the coating film gradually shrinks to the smallest area under the action of surface tension after the coating is applied and before it has dried to form a film

Coating leveling is completed by running for 10-15 minutes in a closed, clean tunnel with a certain air flow rate after the painted workpiece is painted.

The leveling of the coating film is the manifestation of the apparent performance of the coating, involving many aspects of the coating, such as viscosity, the rheology of the coating, the matching of raw materials, the design of the pigment dispersion process, the selection of additives and application technology, and the coating process And painting links and many other aspects

Leveling agent is a kind of auxiliary agent that can effectively reduce the surface tension of the coating liquid and improve its leveling and uniformity

There are many types of leveling agents, and the types of leveling agents used in different coatings are not the same

Leveling agents can be roughly divided into two categories:

One works by adjusting the viscosity of the paint film and the time of the leveling agent.

The other one works by adjusting the surface properties of the paint film.

Leveling agents can play the following roles in coatings:

1.

2.

Various coatings need their own characteristics to choose different leveling agents to play the best role, and coating application engineers are required to choose based on experience and conduct necessary tests
