Oxistar – HC (Premium)

“OXISTAR-HC (Premium)” is a chlorine-free oxidized starch, developed for use in the size press and paper coating formulations. It is from the house having unrivalled experience in the field of manufacturing and supplying Spray Starches viz. “DS-HIBURST” and “DS-HIPLY” as well as high quality cationic starches “CATSTAR-450”. Carboxylic groups make the paste of the product more stable to retrogradation. Its paste is relatively clearer and more fluid for better film formation. OXISTAR-HC (Premium) has better water holding capacity and films are stronger. Its use intensifies following:

  • Improved printability and better print ink holding.
  • Better surface strength, wax pick resistance & smoothness
  • Better surface sizing / pigmenting due to excellent film forming
  • More consistent results due control on viscosity
  • Higher pick-up at the size press

Product Description : 

Paste made from “OXISTAR-HC (Premium)” has a greater degree of fluidity and film produced from it is continuous and strongly adherent.
