Speaking of paint, everyone may be familiar with it. Every household always needs some paint to decorate the walls, but did you know? The coating industry also needs antistatic agents. Why is this? Most paints use various flammable solvents as diluents. The static electricity generated during spraying can easily ignite and explode the gases of these solvents during discharge.
The principle of action of cationic antistatic agents is to use their cationic surface activity properties to absorb moisture in the air, polarize themselves, and form an extremely thin conductive layer on the surface. layer, leaking static charges through different channels or reducing the friction factor to suppress the generation of static charges. Constitutes a static leakage channel, so its effect depends on its own structure and the relative humidity of the environment.
The coating industry requires many kinds of surfactants, including emulsifiers, pigment surface treatment agents, pigment wetting and dispersing agents, defoaming agents, flow Leveling agent, anti-mildew, bactericide, antistatic agent, gloss enhancer, slip agent.
When choosing an antistatic agent, there are several things that need to be done to be a qualified paint antistatic agent.
① Great effect in preventing static electricity
② Preventing static electricity Long-lasting effect
③ Good miscibility with film-forming substances
④ Does not affect other properties of the coating, such as not causing the coating film to turn yellow.
