Composition

Powder:

• Beads or granules of Poly Methyl Methacrylate (PMMA)

• Initiator: Benzoyl Peroxide

• Pigments/Dyes

• Opacifiers: Titanium Oxide / Zinc Oxide

• Plasticizer: Dibutyl Phthalate

• Synthetic Fibres: Nylon / Acrylic

Liquid:

• Methyl Methacrylate Monomer

• Inhibitor: Hydroquinone

• Cross-Linking Agent: Ethylene Glycol Dimethacrylate

Shelf Life and Storage

• Best before 36 months under proper storage conditions.

• Store at a temperature between 10 °C to 30 °C.

• Keep powder and liquid containers tightly closed to prevent contamination.

For Liquid

1. Dewaxing Residual Wax

   • Thoroughly flush out any residual wax using boiling water after the dewaxing procedure.

2. Application of Separating Medium

   • Apply a separating medium uniformly to the gypsum surface, excluding the mold space.

   • Allow it to dry completely before proceeding.

3. Mixing the Resin

   • Dispense 5 mL of liquid monomer into a clean mixing cup.

   • Add 10 cc of powder to the liquid by gently tapping the dispensing jar.

   • Do not stir the mixture with a spatula to avoid air entrapment.

   • The resin will achieve a dough-like consistency within 20–30 seconds from the start of mixing.

4. Packing the Resin

   • Remove the dough in one piece from the mixing jar, taking care not to introduce air bubbles.

   • Pack the resin into the invested mold in the flask.

   • The resin remains workable for approximately 8 minutes from the start of mixing.

5. Bench Curing

   • After packing, allow the resin to bench cure for 30 minutes under a pressure of 30–85 psi.

6. Polymerization (Heat Activation)

   • Option A: Place in a 74 °C water bath for 8 hours, then increase the temperature to 100 °C for 1 hour.

   • Option B: Place in a 74 °C water bath for 2 hours, then increase the temperature to 100 °C for 1 hour.

7. Post-Processing

   • After deflasking, immerse the processed denture in a plaster dissolvent to remove any residue.

8. Finishing and Polishing

   • Once cured, trim, shape, and polish the acrylic to achieve the desired fit and finish.

9. Storage

   • Store in a cool, dry place, away from direct sunlight.

   • Shelf life: 36 months under proper storage conditions.

For Powder

1. Surface Preparation

   • Ensure the application surface is clean and dry before use.

2. Measuring the Powder

   • Measure the required quantity of Maarc Heat Cure Powder, available in 100 g, 400 g, 500 g, 1 kg, 3 kg, and 5 kg packs.

3. Mixing with Liquid Monomer

   • Combine the measured powder with the liquid monomer in a clean, dry container.

   • Recommended powder-to-liquid ratio: approximately 3:1.

4. Adjusting Consistency

   • If the mixture is too thick, add a small amount of liquid monomer.

   • If too thin, add more powder until the desired consistency is reached.

5. Working Time

   • The mixed acrylic has a working time of around 4 minutes, during which it can be shaped and adapted as needed.

6. Application

   • Use the prepared acrylic paste to fill the desired area, such as for dentures, partial dentures, crowns, bridges, and other dental prostheses.

7. Heat and Pressure Application

   • Apply heat and pressure to initiate polymerization.

   • The product is specifically designed for heat-curing applications.

8. Curing

   • The material typically cures in 10–15 minutes under recommended conditions.

9. Finishing and Polishing

   • Once cured, trim, contour, and polish to achieve the final shape and smooth surface.

10. Storage

    • Store in a cool, dry place, away from direct sunlight.

    • Shelf life: 36 months under proper storage conditions.
