Zinc Phosphate Cement

Zinc phosphate dental luting cement as hardward cement. Zinc Phosphate Cement. Three groups of (GC Elite cement 100) with different expiry dates were tested for compressive strength using a universal testing machine (crosshead speed 1 mm/min: load cell of 250 kgF). Elite 100 is unbeatable in terms of its physical properties such as strength, film thickness and low solubility.

The results showed that there was a significant difference (p<0.05) between the compressive strengths of zinc phosphate cement. Group III (2 months before expiry date). Group I (2 years and 5 months before expiry date), and group II (11 months before expiry date).
