APC™ II Adhesive Coated Appliance System
Faster, more efficient bonding than any other system.
3M Unitek set a new benchmark in orthodontic bonding efficiency with the introduction of APC™ Adhesive Coated Brackets in 1991.

Today, the innovative APC II System takes bonding ease and efficiency to the next level – a softer and more workable APC II adhesive, dramatically easier etching / priming with Transbond™ MIP Moisture Insensitive Primerand faster curing with Ortholux™ LED Curing Light, besides more appliance types with adhesive pre-coating to match the orthodontist's preferences. Fewer steps, far lesser bonding variables and increased productivity ensure faster and efficient bonding, far ahead of any other system.
Softer, more workable adhesive.
The APC II adhesive is lighter and less viscous than the original APC adhesive. While being soft to assure accurate placement, it is also firm enough to virtually eliminate bracket drift and excessive flash – ensuring ease of use and consistently high bond strength.
Far lesser bonding variables.
The APC II System has the distinction of being the only orthodontic bonding system that pre-coats each bracket with adhesive. No mixing, no application, no contamination – no hassle.
Less Waste and Clean-up.
The APC II System requires no messy mixing procedures – this means lesser material wastage and avoids the need to clean up. Since each individual bracket is clearly identified and pre-oriented on a special foam liner, eliminating bracket rotation in transit and bracket handling problems. This also ensures that there is no time lost in getting to the chair side.
Fewer steps, less time consumption

Dispensing System
The compact dispensing system of the APC II adhesive facilitates storage of up to twenty cases of brackets, by slot size, tooth and prescription. What’s more, a convenient patient set-up tray enables the orthodontist to transfer exactly what is needed to the chair side. Each APC II adhesive coated bracket is presented in an individual color-coded well for easy identification, in addition to a tamper-evident heat seal to ensure a three year shelf-life.
