Zinc polycarboxylate cement for permanent luting and lining
Libral Traders Delhi B841 Okhla Inds Area 2
Areas of Application:
Fixation of crowns and inlays, cavity linings
Dispensing Instructions:
Fixation consistency: 2.9 g powder : 1.0 g liquid
Cavity lining consistency: 3.6 g powder : 1.0 g liquid
Dispensing and testing climate for testing in accordance with DIN EN ISO 9917:
Processing Recommendations:
A clean, dry glass plate at approx. 20 degree C (68 degree F) and a non-discolouring spatula are recommended for mixing.
Mixing:
Divide the measured quantity of powder into 3 portions (1/2 1/4 1/4). Beginning with the largest quantity, stroke the powder into the measured liquid within 60 seconds. The mixture should appear thicker as usual for zinc phosphate cement, yet it is just as easy to work. The fixation consistency has been reached when the peak formed on lifting the spatula slowly falls back into the paste. The filling consistency has been reached when on lifting the spatula, the peak drawn out forms a small hook and does not sink back into the paste. Discard remaining powder or impure liquids.
Mixing Time:
60 seconds
Processing Time from start of mixing (at 23 degree C, 72 degree F):
For fixation: 2 minutes
For cavity linings: 1 minute 30 seconds
Setting Time from end of mixing: 2:30 – 6:00 minutes
Special Informations:
- The mixed cement should never be applied directly onto dentine near to pulp or onto exposed pulp
- Apply the thinnest possible layer for fixations
- The cement must be applied to the dry tooth surface and must set without contact to moisture
- Remove excess material from neighbouring teeth, facets etc. immediately
- Do not expose liquid to sunlight and frost
- Close containers immediately after removing material
- Clean instruments and glass plate with water before the cement sets Zinc polycarboxylate cement can be dissolved using a cement-solvent after setting
