• Pigments:
  The most common pigments used in paper emulsion coating are titanium dioxide, kaolin clay, and carbon black. Titanium dioxide is used to give the coating its whiteness and opacity. Kaolin clay is used to give the coating its smoothness and gloss. Carbon black is used to give the coating its black color.

• Binders:
  The most common binders used in paper emulsion coating are acrylic, vinyl acetate, and polyurethane. Acrylic binders are water-based and are easy to apply. Vinyl acetate binders are more durable than acrylic binders, but they are also more difficult to apply. Polyurethane binders are the most durable binders, but they are also the most expensive.

• Additives:
  The most common additives used in paper emulsion coating are defoamers, lubricants, and biocides. Defoamers are used to prevent the coating from foaming. Lubricants are used to make the coating easier to apply. Biocides are used to prevent the growth of mold.

High Shear & High Viscosity Mixing Technology
for Paper Emulsion Coating Manufacturing

High-shear mixers or high-shear homogenizers are used to produce standard mixtures of ingredients that do not naturally mix. This industrial machinery disperses, or transports, one phase or ingredient (liquid, solid, gas) into a main continuous phase (liquid), with which it would normally be immiscible. A rotor, together with a stationary component known as a stator, or an array of rotors and stators, is used in a mixing tank containing the solution to be mixed, and in a pipe through which the solution passes, to create shear. A high-shear homogenizer mixer is used to create emulsions, suspensions, lyosols (gas dispersed in liquid), and granular products. It is used in the food, pharmaceutical, adhesives, chemical, cosmetic, and plastics industries for emulsification, homogenization, particle size reduction, and dispersion.

Key design factors in the high shear mixers include the diameter of the rotor and its rotational speed, the distance between the rotor and the stator.
