kerr single component Total-Etch Adhesive optibond s

describle:

OptiBond™ S is a single-component adhesive designed for both direct and indirect bonding applications. It is 15% filled with the same 0.4 micron filler found in the Kerr Point 4 composite. The filler not only reinforces the hybrid zone but also penetrates the dentin tubules, creating a true "structured bond" not found in unfilled or even "nano" filled adhesive systems.This unique technology provides the highest level of protection against microleakage, while sustaining high bond strengths to a variety of surfaces.
