Alloybond resin matrix

4-meta resin matrix

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 one. 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.

Amalgam to dentin bond strength (MPa)**

Alloybond is twice as strong. Permite amalgam used.

Cumulative fluoride release**

Alloybond releases fluoride. All-Bond 2* and Amalgambond Plus* do not.


1. The Alloybond acetone based primer penetrates deeply into the dentin tubules and surrounding hybrid zone forming a retentive Hybrid-Lock. Complete sealing eliminates microleakage and post operative sensitivity. Alloybond provides effective pulpal protection.			2. The Alloybond resin tags form at the peripheral of the amalgam restoration; without interfering with the amalgam setting reaction. (Permite amalgam used)

			3. Alloybond’s adhesive component forms resin tags that mechanically lock into the amalgam restoration.

			4. Alloybond creates a complete merge between the amalgam and resin.

Application time comparison**

Alloybond is quick and uncomplicated.
