Structural formula

 


Properties

  • Cross-linked by various methods
  • Adding a cross-linking agent
  • Self cross-linking by thermal treatment
  • UV cross-linking (in a hydrous or aqueous solution state)
  • Functions as a protective colloid and a surfactant
  • Adheres well to polarized surfaces
  • Enables to form chelate
  • Easy to unchain cross-linking by alkaline

 

Applications

[Close]

  • Emulsifier
    When used as an emulsifier for vinyl acetate-based emulsion, the resulting emulsion will have a higher degree of water-resistant bond strength which is not achieved by conventional PVOH products.
  • Coating Agent
    There is an increasing demand for GOHSENX™ Z for coated and non-coated paper products which require a higher degree of water resistance. As a coating agent for thermal printing paper and ink jet printing paper, GOHSENX™ Z is extremely popular.
  • Adhesive and Binder
    GOHSENX™ Z excels in adhesion to various materials and has outstanding water resistance. We are currently expanding the scope of adhesive and binder applications.
