Dispersant of Dye and Developer for Thermal Recording Paper

GOHSENX™ L is well used for Dispersant of dye and developer for thermal recording paper thanks to following features.

  • Easy to prepare fine particles in a short time
  • Superior in stability of the dispersion
  • To improve image of resolution and stability of the whiteness
  • Superior in antifoaming property

Emulsifier for Acrylic Emulsion Synthesis

GOHSENX™ L enables the polymerization of acrylic emulsion which is not achieved by general PVOH. The achieved emulsion has good stability, high adhesive strength, excellent dry film performances.
