When it comes to paint, everyone may be familiar with it. Every household always needs some paint to decorate the walls. Did you know that? The paint industry also needs antistatic agents, why? Most paints use various flammable solvents as diluents, and the static electricity generated during spraying is very easy to ignite and detonate the gases of these solvents during discharge.
The principle of cationic antistatic agent is to use its cationic surface active properties to absorb moisture in the air, polarize itself, and form a very thin conductive film on the surface Layer, through different channels to leak static charge or reduce the friction factor to suppress the generation of static charge. Constitutes a static leakage channel, so its effect depends on its own structure and the relative humidity of the environment.
The coating industry needs many kinds of surfactants, including emulsifiers, pigment surface treatment agents, pigment wetting and dispersing agents, defoamers, fluid Leveling agent, anti-mildew, fungicide, antistatic agent, brightening agent, slip agent.
When choosing an antistatic agent, you need to be able to do a few points to be a qualified antistatic agent for coatings.
① Anti-static effect is great
② Anti-static Long-lasting effect
③ Good miscibility with film-forming substances
④ It does not affect other properties of the coating, such as not making the coating film yellow.
