AT Series — Antistatic Coating Agents

AT Series — Antistatic Coating Agents

The AT Series coating agents (water-dispersed type) offer excellent antistatic properties even at low humidity and have excellent transparency, adhesion to substrates, and stability over time. These coating agents are effective in preventing or reducing static electricity on film.
