Advantages of Zinc Phosphate Cement:
- Zinc phosphate cement is stronger (103.5 MPa) than zinc oxide-eugenol.
- The strength is sufficient when used as a base or luting agent.
- Its modulus of elasticity is high. This makes it stiff and resistant to elastic deformation.
- This is necessary when it is employed as a luting agent for restorations that are subjected to high masticatory stresses.
- Zinc phosphate cement is a good thermal insulator and may be effective in reducing galvanic effects.

Disadvantages of Phosphate Cement:
- When phosphate cement is exposed to the oral environment,
- For example, Temporary restorations, its bitterness and low strength cause it to fracture and disintegrate.
- Tensile strength is weaker, thus making it brittle.
- In the mouth, they show greater disintegration over a period of time.
