Much of the success of Kuraray Noritake Dental’s adhesive has come off the back of our originally developed MDP monomer (10-Methacryloyloxydecyl dihydrogen phosphate). After applying for a patent for it in 1981, we started using this monomer’s excellent chemical adhesion properties, hydroxyapatite and metals in PANAVIA EX, our first adhesive resin cement, as well as in our CLEARFIL SE BOND adhesive. Through a process of extensive research and development, we have been able to combine our MDP monomer with hydrophilic amide monomers to create rapid bond technology. Our new universal adhesive system CLEARFIL Universal Bond Quick relies on this technology to deliver a lasting bond faster, and easier, than ever. By building on our past successes to deliver better solutions, this new technology embodies what Kuraray Noritake Dental does best—innovate and develop new and improved products.

Dentin bonding
Bonding to a substrate such as dentin can be difficult, as the adhesive needs to be able to penetrate the dentin. For many other adhesives, their reliance on slow monomers means that there is slow penetration of the dentin layer. Rapid bond technology’s use of amide monomers gives CLEARFIL Universal Bond Quick superior hydrophilic properties in comparison to traditional monomers, such as HEMA, which allows it to penetrate the dentin faster and more effectively. By doing so, the time spent waiting between applying the adhesive and proceeding with air-drying is eliminated and a tight and impermeable seal of the cavity is created after light curing. Thanks to rapid bond technology, bonding with CLEARFIL Universal Bond Quick can be performed easily and efficiently with the added assurance of predictable clinical outcomes.

Low water sorption
When it comes to dentin bonding, the level of water sorption in the bond’s organic matrix is a key indicator of long-term success. A high rate of sorption has demonstrated to be a prominent factor in the progressive physical deterioration of bonds, which can lead to secondary caries. Potentially, due to both the high cross-linking properties of the amide monomers used in our rapid bond technology and the use of almost insoluble Ca-MDP salt, CLEARFIL Universal Bond Quick has a low rate of water sorption. As a result, bonds that are created using this adhesive are more stable and resistant to hydrolytic degradation.

Aesthetic bonding
Rapid bond technology does not only provide a basis for bonding excellence. With a thin film layer of 5–10 μm, CLEARFIL Universal Bond Quick’s aesthetic appeal is evident. Through the aforementioned dense crosslinks of its polymer network, rapid bond technology is able to reinforce the stability of this layer and provide resistance to discolouration.

As the engine powering CLEARFIL Universal Bond Quick, rapid bond technology represents the next step for Kuraray Noritake Dental. Finally, faster and more reliable bonding procedures with consistent and durable results are now possible.
