Aluminophosphate binder UNIBOND-1

Technical Data Sheet

Aluminophosphate binder is a viscous liquid, which is a high temperature aluminum phosphate adhesive. It is used at temperatures up to 1600 ⁰С. Possesses significantly higher durability and strength in comparison with silicate- based bonds.


Basic features and application

  • In ferrous and non ferrous metallurgy as a binder in the installation and repair of linings, extending their service life (pouring ladles and furnaces, laying doors of coke oven batteries, etc when laying bricks in furnaces, when gluing glass and ceramics, when installing high temperature sensors etc
  • Manufacturing of refractory masses ( rammed silica masses), non fired refractory products, porous and dense products from fused quartz powders
  • In the glass industry for fixing the thermal insulation of glass furnaces, preventing the penetration of molten glass through the masonry

Recommendations for use

  • Curing of the aluminium-chromium-phosphate binder occurs at a temperature of 100 ° C and above
  • The optimum rate of temperature rise in the temperature range 20–100 ° C and 200–280 ° C is no more than 2 ° C / min, and in the temperature range 100–200 ° C no more than 1.5 ° C / min
  • The mechanical strength of the glue line depends on the type of materials to be glued

Storage and safety

Avoid direct sunlight. The minimum shelf life in proper conditions and in original unopened packaging is 4 years.
