ZR-CEM – Zirconia Cement
Yttria Stabilized Zirconia Cement
Low Shrinkage… High Strength… Cement Adhesive…
High temperature bonding for porous zirconia insulation. Bond ZYFB boards into larger assemblies, or ZYF or ZY textiles into any shape required.
Zircar Zirconium Oxide Cement Type ZR-CEM is an off white single part yttria-stabilized zirconia adhesive with a useful temperature limit of 2200 °C. ZR-CEM is formulated specifically for bonding our ZrO₂ fibrous ceramic felts, boards and cylinders to themselves or to porous back-up thermal insulations such as porous firebrick, alumina and alumino-silicate fiber boards. ZR-CEM is manufactured from Zircar ZYBF Bulk Fibers which are made using the original ZIRCAR process at our plant in Florida, NY, USA.
ZR-CEM is composed of ZYBF yttria-stabilized zirconia milled fibers and sub-micron particles. Potassium silicate and zirconium acetate binders are added to enhance bonding characteristics. ZR-CEM is mildly acidic (pH 5) and forms a strong bond upon drying and firing.
