About Inorganic Ceramic Adhesive Cements

Inorganic Ceramic adhesive cements are made from selected high quality material consisting of binders, additives and chemicals to exhibit typical characteristics like high adhesion, excellent bonding strength, high temperature resistance, thermal and electrical insulation etc.

Our range of chemical setting inorganic ceramic adhesive cements, are ideal for potting, bonding, sealing and coating applications because these cements contain a catalyst which hardens the mass or solidifies as needed for the application. Heat may be applied gradually to accelerate the curing process. These cements are made of either a single component or two components.

Inorganic ceramic adhesive cements are used for cementing,adhesing applications because they known to perform better at high temperature as compared to conventional polymer adhesive cements, at high temperatures.moreover,they are non toxic,non hazardous,non flamable & user friendly

Advantages in using Ceramic Adhesive Cements :

  • They are non-toxic, non-hazardous, non-flammable and user friendly
  • Temperature resistance is approximately 15 times higher than most epoxy adhesives
  • High Di-electric strength above 1000volts/mm
  • Curing time may be adjusted to suit needs of application or user
  • Thermal conductivity up to 20 btu in / ft^2 / hr / °F

Criteria for selection

  • Nature of the application-Joining,sealing,insulation,coating etc
  • Maximum service temperature required from the ceramic adhesive cement

Jyalucem-20

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 parts by wt. 20 parts by wt.

Method :

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).

Curing :

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 development of cracks in the cemented area.

Caution :

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

Zircocem-1

Zircon Based - 2 Components - Cold Curing

Zircocem-1 is a 2 component, zircon based, inorganic ceramic adhesive cement with chemical setting having low thermal expansion. Its 2 components consist of a fine dry powder (Part I) and a liquid (Part II) as the curing agent to be mixed together to form the cementing paste, in the specified ratio as given below:

Mixing Ratio :

Powder (Part I) Liquid (Part II)
2 Parts by wt. 1 part by wt.
80 Gms by wt. 40 gms by wt

Method :

Shake the liquid (Part II) thoroughly before weighing and place in a clean dry container. Add the Zircocem-1 (Part I) powder gradually to this weighed liquid (part II) and mix thoroughly to make a smooth uniform paste of tooth paste consistency. Mixing can be done manually using a spatula or in a mixer at a slow speed. Use the cement paste immediately.

Caution :

Do not use excess quantity of liquid for it will reduce the mechanical strength and the cement may fail to adhere properly. Do not attempt to re- temper by adding more liquid to the cement paste. However, this cement can be mixed to a marginally thinner consistency by regulating the quantity of the (Part II) liquid component.

Curing :

Since Zircocem-1 ceramic adhesive cement is very quick to dry, it is important to finish the mixed quantity within 15-20 minutes of mixing, before it hardens. Leave the cemented parts to air-dry for a period of 18-24 hours at ambient temperature. If the ambient temperature is lower than 25°C/77°F, gentle oven heating at 90°C (194°F) for 1½ to 2 hours may be implemented. Do not apply direct heat and avoid steaming of entrapped moisture while drying, as this may develop cracks on the cemented areas.
