Cold Cure

Cold Cure (Self-Cure) Acrylic Resin for Denture Repair, Relining and Special Trays

Cold cure (also called self-cure or auto-polymerising) acrylic resin is a polymethyl methacrylate (PMMA) powder + liquid system that polymerises at room temperature in 5–10 minutes — used for denture repair and relining, special acrylic tray fabrication, orthodontic baseplates (Hawley retainers, expansion plates), and bite-registration record bases. Dentalkart stocks DPI RR Cold Cure (the classic Indian lab and clinic standard) and Maarc cold cure powders and monomer in multiple sizes — 100 g, 110 g, 400 g, 3 kg jars and 4-litre lab packs.

Types of Cold Cure Acrylic

DPI RR Cold Cure (Repair Resin)

The most widely used Indian self-cure PMMA — fine polymer beads + monomer that set chairside or on the bench in 5–8 minutes — for example, DPI RR Cold Cure Powder Jars 3 kg for lab-volume use.

Maarc cold cure powder and monomer

Indian self-cure PMMA in 100 g, 3 kg and lab-pack powder formats plus 4-litre monomer bottles for high-volume denture clinics and dental colleges, for example, Maarc Cold Cure Powder 3 kg and Maarc Cold Cure Monomer 4 Litres.

Bulk powder + liquid monomer separate-pack format

Powder-only jars (110 g, 400 g, 3 kg) and liquid-only monomer bottles let labs and colleges stock the two components independently and mix custom batches — economical for high-volume practices that already have the matching liquid or powder on hand.

When Cold Cure Acrylic Is Used

• Denture repair (fracture line bonding, tooth re-attachment, flange addition)
• Chairside denture relining for ill-fitting dentures
• Custom acrylic tray fabrication for secondary edentulous impressions
• Orthodontic baseplates — Hawley retainers, expansion plates, habit-breaking appliances
• Bite-registration record bases for maxillomandibular relation recording
• Temporary denture and immediate denture relining
• Dental college teaching of denture processing and repair

How to Use and Choose Cold Cure Acrylic

1. Maintain the correct powder-to-liquid ratio (typically 2:1 to 2.5:1 by volume) — over-monomer mixes shrink and warp, over-powder mixes are grainy and weak.
2. Mix in a glass or porcelain dappen dish, cover during the sandy stage, and pack when the mix reaches dough consistency (about 90 seconds).
3. Pack into the repair or tray mould before stringy stage; pressure-cure under a load (kitchen-press or pressure pot) for 15–20 minutes for best mechanical properties and lowest porosity.
4. Pick DPI RR Cold Cure for clinic and college standard use; pick Maarc for high-volume lab packs and 4-litre monomer at economical pricing.
5. Match powder and liquid from the same brand and same lot whenever possible — cross-brand mixing changes set time and shade.
6. Store powder cool and dry; keep monomer in dark amber bottles away from light to preserve shelf life.

Why Buy Cold Cure Acrylic from Dentalkart

Every cold cure pack is sourced direct from the manufacturer or authorised Indian distributor, ships with manufacturing date and expiry printed on every jar and bottle, and reaches 110000+ pincodes across India with COD on most SKUs. Pair cold cure with heat-cure denture base material, custom trays and articulator records to complete the full denture workflow — from one trusted catalogue serving 50,000+ dentists and dental colleges.

What is cold cure acrylic used for?

Cold cure acrylic is used for denture repair, chairside denture relining, custom acrylic tray fabrication, orthodontic baseplates (Hawley retainers, expansion plates, habit appliances) and bite-registration record bases. It auto-polymerises at room temperature in 5–10 minutes without needing a flask or water bath, which makes it ideal for chairside and benchwork use.

What is the difference between DPI RR Cold Cure and DPI Heat Cure?

The difference between DPI RR Cold Cure and DPI Heat Cure is polymerisation method and indication. DPI RR Cold Cure auto-polymerises at room temperature in 5–10 minutes and is used for repairs, relines and special trays. DPI Heat Cure polymerises at 70–100 °C in a flask water bath and is used for primary complete denture base fabrication.

What is the correct powder-to-liquid ratio for cold cure acrylic?

The correct powder-to-liquid ratio for cold cure acrylic is typically 2:1 to 2.5:1 by volume. Over-monomer mixes shrink and warp during polymerisation; over-powder mixes are grainy, weak and have unreacted powder beads. Follow the manufacturer's measuring scoop and dropper for consistent results across DPI RR Cold Cure and Maarc cold cure systems.

Can I cure cold cure acrylic in a pressure pot for stronger results?

Yes, you can cure cold cure acrylic in a pressure pot at 20 psi in warm water for 15–20 minutes for stronger results. Pressure-curing reduces porosity, increases the degree of conversion, and improves the mechanical properties of the cured acrylic — especially important for denture repairs and orthodontic baseplates that take occlusal load.

Are the cold cure acrylics on Dentalkart genuine with valid expiry?

Yes, every cold cure acrylic pack on Dentalkart is genuine with valid expiry. All DPI and Maarc cold cure powders and monomers are sourced direct from the manufacturer or authorised Indian distributor and ship in sealed jars and bottles with the original lot number, manufacturing date and expiry printed on every pack.
