- Mixing Ratio
Its 2 components consist of a fine dry powder (Part 1) and liquid (Part II) as the curing agent to be mixed together to form the cementing paste, in the ratio as specified below:
Powder (Part I) Liquid (Part Il) 2 Parts by wt. 1 part by wt. 80 Gms by wt. 40gms by wt. - Method
Shake the liquid (Part Il) thoroughly before weighing and place in a clean dry container. Add Zircocem-1 (Part 1) 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 by manually using a spatula or in a mixer at a slow speed. Use the cement paste immediately. Since Zircocem ceramic adhesive cement is 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 room temperature. If the room temperature is lower than 25°C /77°F, gentle oven heating at 90°C (194°F) for 1% to 2 hours may be implemented. Do not apply direct heat and avoid steaming (of entrapped moisture) while drying, as this may develop cracks in the cemented areas. Caution: This cement can be mixed to a marginally thinner consistency by regulating the quantity of the (Part Il) liquid component. However, use of excess quantity of liquid will reduce the mechanical strength and it may fail to adhere properly. Do not attempt to re- temper by adding more liquid to the cement paste.
