Alloybond is a high strength, fluoride releasing, amalgam bond

Alloybond’s unique dimethacrylate resin groups provide twice the cross linking and superior strength.

Alloybond does not contain BisGMA nor Bis-Phenol A.

Twice the cross linking

SDI’s unique dimethacrylate resin, with carboxylic groups, provide twice the cross linking compared to the 4-meta system. The SDI resin system contains two cross links per chain when polymerized, whilst the 4-meta monomethacrylate system cross links only once. Additional cross links create a stronger resin matrix, superior chemical bonding and higher cohesive strength.

Denser resin matrix

The Alloybond monomers are more closely arranged for a stronger resin matrix.

Stronger resin matrix

SDI’s Alloybond offers stronger dentin bond strength, without the complication of adding filler required by other amalgam bonds.

Isolate tooth, prepare cavity.

1. Etch tooth surface with 37% phosphoric acid for 20 seconds

2. Wash thoroughly

3. Remove excess water. Keep moist

4. Apply Alloybond Primer to saturate all internal surfaces.

5. Blow gently with dry, oil-free air for 2 seconds to evaporate solvent. Leave surface glossy

6. Light cure for 10 seconds

7. Mix one drop of Alloybond Base and one drop of Alloybond Catalyst.

8. Apply mixture to all internal surfaces.

9. Start trituration of amalgam.

10. Condense and carve amalgam within 60 seconds of applying Alloybond Base and Catalyst mixture, or place composite 60 seconds after applying Alloybond Base and Catalyst mixture
