Jyalucem-20 powder Clean tap water 80 parts by wt. 20 parts by wt. - Applications
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.
- Potting of lamps into lamp housing
- Potting elements into base
- Encapsulation of resistor wires & electrical heating elements
- High thermal conductivity
- Maximum service temperature 1575°C (2867°F)
- Lining of furnace doors and walls
- 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 cleaned and abraded parts to be cemented and air dry them for 4 to 5 hours at an ambient temperature (25°C- 40°C). 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 minutes to 1 hour. Caution: Due to the moisture that may be entrapped during the curing process, it is best to raise the temperature of the heating system gradually from room temperature to 200°C(392°F), to prevent development of cracks in the cemented area.
