• Strong adhesive properties
• Low initial pH for bonding
• Versatile for various dental procedures
• Precise powder-to-liquid ratio
• Quick mixing and setting times
• High compressive strength after curing

DPI Zinc Phosphate Cement is a versatile dental product used for luting permanent metal restorations and as a base in dental procedures. With its low initial pH, it provides strong adhesive properties but requires careful application to prevent pulpal irritation, especially in cases where thin layers of dentine separate the cement from the pulp.

• 1 x 30 gm powder
• 1 x 15 ml liquid

• Adhesive Properties: Strong with low initial pH
• Environmental Conditions: 22-24°C temperature, 50±10% humidity
• Mixing Surface: Clean, dry glass mixing slab or paper
• Mixing Tool: Non-corrosive spatula, free from dust
• Powder-to-Liquid Ratio: Cement: 1.20-1.60g powder to 0.5ml
• Liquid Base: 1.2-1.6g powder to 0.5ml liquid
• Mixing Technique: Gradual addition of powder to liquid until plastic consistency is achieved
• Mixing Time: Approximately 60 sec
• Setting Time: Cement: 2.5 to 5 minutes
• Compressive Strength (after 24 hours): 70 MPa

• Ratio: The powder/liquid ratio at an ambient temperature 23±1⁰C is 1.20 – 1.60g powder to 0.5ml liquid.

  Mixing:

  1. The recommended ambient temperature for mixing is 23±1⁰C.

  2. Place an appropriate amount of powder and liquid on clean and dry, polished glass slab using an agate, stainless steel or stellite spatula.

  3. Incorporate successive small increments of powder into the liquid. Spatulate thoroughly after each addition until the desired consistency is obtained.

  4. Higher temperature accelerates and lower temperatures retard the setting of the material, therefore, recommended that the glass slab be cooled in hot weather, care being taken to avoid condensation.

  Mixing time:

  1 – 1½ minutes, rapid incorporation of powder accelerates the setting time, slow mixing retards.

  Average working time:

  1 minute from end of mix, do not add liquid once mixing has commenced.
