About Inorganic Ceramic Adhesive Cements Jyalucem®-20 Zircocem®-1 Zircocem®-5 Zircocem®-C9 Alucem®-HT2

Alumina Based - Single Component - Heat Curing

Jyalucem-20 is an inorganic, low temperature (200°C / 392°F) curing, high temperature resistant Inorganic Ceramic Adhesive Cement.
After proper curing, this cement imparts high bonding strength, thermal shock resistance and a hard surface.
It is available in a Micro-fine dry powder form, to be mixed with clean tap water, in the ratio specified below:

Mixing Ratio
Jyalucem-20 Powder
Clean tap water
80 -75 parts by wt.
20- 25 parts by wt.

Mix the cement powder thoroughly with clean tap water in the above mentioned ratio to prepare a smooth uniform paste of tooth paste consistency. Apply this paste with a suitable tool like a spatula, on thoroughly cleansed and abraded parts to be cemented and air dry them for 4 to 5 hours at an ambient temperature (25°C- 40°C/ 77°F -104°F).

Heat cure, the cemented parts at approximately 200°C (392°F) in an oven for 2–3 hours and maintain the same temperature for 30 mins to 1 hour. Due to the moisture that may be entrapped during the curing process, it is best to raise the temperature of the heating system very gradually from room temperature to 200°C (392°F) to prevent cracks from developing in the cemented area.

Do not use excess quantity of water while mixing the cement for it will increase shrinkage and reduce mechanical strength.


Jyalucem-20 is ideal for high temperature cementing / sealing / bonding of ceramic to ceramic, ceramic to metal, ceramic to glass, glass to glass, glass to metal, & refractories.
