Oxistar- HC

Introduction

  • “OXISTAR-HC” is a Chemically Modified Starch, developed for use on the size press.


  • “OXISTAR-HC” has greater degree of fluidity and film produced from it is continuous
    and strongly adherent.


    • ADVANTAGES

    OXISTAR-HC provides the paper maker:

    • Improved printability and better print ink holding
    • Better surface strength& smoothness
    • Improves BF & other internal Strengths
    • More consistent results due to control on viscosity
    • Higher pick-up at the size press
    • No phase separation

    PROPERTIES

    • Good paste stability, clarity and reduced tendency to retrograde.
    • Lower pasting temperature.
    • Pastes are more stable to salts and hard water
    • Tough, clear and flexible films
