GOHSENX L - Anionic Grade

GOHSENX L has excellent properties beyond those of standard PVOH resins. It is used as an emulsifier, dispersant, adhesive, coating agent, and binder, and new applications are being found regularly.

It is a modified PVOH with a sulfonic group (-SO3X group) on its side chain.

PROPERTIES

L-3266

  • Excellent emulsifying power and protective colloid properties.
  • In acrylic or styrene emulsion form, it is capable of stable emulsification polymerization unachievable with standard PVOH. The GOHSENX-based emulsion boasts excellent stability and has various additional features.
  • It is a powerful dispersant of organic or inorganic materials.

L-025、L-823

  • As well as being water-soluble, these grades are also soluble in an organic solvents such as methanol, ethanol, methyl acetate or acetone, and in aqueous mixture solutions.
  • They become molten at a temperatures of 100 to 180 degree C, and are capable of coating and bonding as a hot melt materials.
  • They are effective as a dispersant or binder for organic or inorganic material.
