SOMAREX is a chemical to be added into coating colors for improving water retention and visco-elasticity, and as a result improves coated paper properties and coating operation.
As it is an aqueous emulsion, handling characteristics are good. Various product types suited for each application are available.

Improvement of Water Retention

Control of Binder Migration

Solves troubles in printing to be caused by binder migration. Settles calendering stains.

Control of Binder Migration

Improvement of Bulkiness of Coated Layers

Improves coated paper properties (brightness/smoothness). Improves gravure fitness.

Improvement of Bulkiness of Coated Layers

Controls excessive dewatering into base paper

Decreases web break during the coating.
Reduces streaks/scratches.

Viscosity Control

Replaces CMC

Gives same effects with less addition.
Can be added directly without any dissolving processes.

Stable coated volume on white boards

Keeps stable coating profiles with free viscosity adjustment.

Improvement of Rheology

Control of Bleeding

Improves visco-elasticity of coating colors, and controls occurrence of bleeding.

Control of Bleeding

Influence of Water Rheology

Restrains penetration of coating color water into base paper, and improves coating operation.
Keeps the coating layer under the blade wet.

Influence of Water Rheology

Directions for Use

  • Add 0.05 to 0.3 parts of active ingredients by solid to the coating color.
  • To be added during agitation at the final stage of the coating color production process, and then dispersed evenly.
  • Produces effects under alkaline conditions with NH4OH, NaOH, etc.
  • As it produces effects under alkaline conditions, final pH to be adjusted to over 8.5.
  • Depending on the prescription, it can improve water retention by adding during production.

* For applications other than the above, it is suggested that you consult us.

Precautions in Handling

  • During the use, please wear protective gear, and operate in well ventilated areas.
  • As it freezes below 0 °C, please take enough care in storing.
  • In case of entry in eye, please flush immediately with plenty of water and consult a doctor.
  • In case of contact on skin, please wash out with soap and water.
  • In case of swallowing, please immediately consult a doctor.
  • When it is spilled out, please get the spill coagulated with salts (ex. aluminum sulfate, sodium chloride, etc.), and then incinerate.
  • Please read MSDS at the use of product.
