Aluminium-chromium-phosphate binder UNIBOND-2

Technical Data Sheet

Aluminium-chromium-phosphate binder is a viscous liquid of dark green color which is a universal hightemperature adhesive and a binder based on aluminum and chromium phosphates. It is used at temperatures up to 1800 ⁰С. It has a significantly higher durability (up to 4 times) compared to silicate- based bonds.


Key properties and application

  • In ferrous and non-ferrous metallurgy as a binder for the installation and repair of lining of furnaces, smelting units and boilers, fastening of heat-resistant sensors, for laying furnaces made of fire-resistant bricks, as well as heat-insulating plates based on fiberglass and mineral wool, etc.
  • Possesses high chemical and thermal resistance, fire resistance
  • Provides excellent wear resistance to products
  • Does not interact with molten metals and slags

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
