Keystone Diamond D Self Cure Denture Acrylic · Dark Veined · 1 lb
SKU 010-0520MFR# 1013109
Shade
Dark Veined
Size
1 lb
Keystone Diamond D Self Cure, Original, 1 lb is an acrylic denture resin. It is formulated for use in dental applications, specifically for the fabrication, repair, and relining of dentures.
This material is a self-cure resin, eliminating the need for external heat or light polymerization. The original formulation is provided in a 1 lb container, suitable for dental laboratories and clinics requiring a reliable, self-curing acrylic for various denture procedures.

About self-cure denture resin
A self-cure resin, also called cold-curing or autopolymerizing, is one whose polymerization is sped up by a chemical instead of heat. Its polymerization is never as complete as that of heat-activated resin, which leaves more free monomer: 3 to 5 percent against 0.2 to 0.5 percent.
The denture base is the part of a removable denture that carries the artificial teeth and covers the soft tissue of the mouth. Polymethyl methacrylate, PMMA, has been the most widely used denture base material since 1937. It comes as a powder of pre-polymerized PMMA beads with a little initiator, and a liquid of methyl methacrylate monomer.
The FDA regulates denture relining, repairing or rebasing resin, the resin that forms a new denture base, as a Class II device (21 CFR 872.3760). ISO 20795-1 classifies denture base polymers and sets their requirements.
How the types of denture resin differ
- Heat-Cure Denture Resin — Cured with heat; a review reports greater surface hardness and lower sorption and solubility than cold-cured resin.
- Pourable Denture Resin — A very fluid mix that is poured into the mold.
- Self-Cure Denture Resin — Set off by a chemical activator instead of heat.
- Orthodontic & Retainer Resins — Acrylic for orthodontic appliances, active or passive, not for denture bases.
- Repair Acrylics — The acrylic used to mend a cracked or broken denture.
- Flexible Denture Resin — A thermoplastic that flexes, injected into the mold instead of being mixed from powder and liquid.
What to look at when choosing a denture resin
Residual monomer: most of it is released in the first twenty-four hours after processing, followed by a moderate and steady release.
Impact strength: high-impact resins are reinforced with butadiene-styrene rubber and are handled like other heat-activated resins, as powder and liquid.
Processing: with heat-cured PMMA, a review reports less polymerization shrinkage for injection molding than for conventional compression molding.
Flexible resins: nylon, a polyamide, is used mainly for flexible tissue-supported partial dentures. The same review notes that polyamides are challenging to process and repair.
Standard: under ISO 20795-1 water sorption should be less than 32 micrograms per cubic millimetre and solubility less than 1.6.
