Prime & Bond NT is one of the few "one-component" (ie, "fifth-generation") bonding products that is marketed for indirect as well as direct bonding. This is possible because its Self Cure Activator enables the user to convert the light-activated adhesive into a dual-cure adhesive. User friendliness is always an appealing feature for bonding agents and Prime and Bond NT does well in this regard. Of eight "one-component" products tested by DIS, Prime & Bond NT was the second fastest to apply, which indicates it is simple and straightforward to use. It also produced a very high bond strength. Intro kit. 4.5ml light cure bonding agent with brush tips, wells, and instructions.
