Surfactant in the coatings industry - antistatic:


Antistatic agent surfactant, which leaks static charge or reduces friction factor through different channels to suppress the generation of static charge. It is generally required to have the following characteristics:
1 Prevents static electricity
2 Prevent static electricity from lasting
3 Good compatibility with film-forming substances
4 Does not affect other properties of the coating, such as not making the coating yellow.


The principle of action of antistatic agent is to use its cationic surface active property to adsorb moisture in the air to polarize itself and form a very thin conductive layer on the surface to form an electrostatic leakage channel. Therefore, its effect depends on its structure and environment. Relative humidity.
Surfactant Applications in the Coatings Industry - Leveling: To use a leveling agent to improve the leveling of a coating, consider the following two factors:
1 Use an active agent that reduces the surface tension of the coating/coating film to greatly improve the leveling of the coating.
2 Use a solvent with a slow volatilization rate to reduce the viscosity of the coating application, improve the fluidity of the coating, extend the leveling time, and achieve final leveling.
