With Dr Fog, no chemicals are used. Chemical systems can have a Damaging Effect (see article) on conveyor belts. Surfactants are designed to break up the surface tension of the water droplet to increase its distribution into the material. Dry Fog produces microscopic droplets that collide with airborne particles and have very little surface tension. Binders are designed to make the material stick together. Dry Fog agglomerates like size droplets to dust particles and the electrical charges present.
