Sika® Air-260

Air Entraining Admixture

Sika® Air-260 is a unique, synthetically manufactured surfactant for the air entrainment of concrete. Sika® Air-260’s patented formula provides superior control of the air content and finishability in air-entrained concrete. Sika® Air-260 increases concrete’s durability, making it more resistant to the damaging effects of freezing and thawing, while improving workability and reducing bleeding. Sika® Air-260 meets the requirements of ASTM C 260.

  • Increases resistance to freeze-thaw cycles and scaling.
  • Improves workability.
  • Reduces bleeding.
  • Improves appearance of architectural concrete.
  • Reduces size and number of capillary channels, increasing impermeability.
  • Substantially increases durability.
  • Provides superior air-void system.
