Blugloo Two-Way Color Change Adhesive for aesthetic brackets Blugloo is the first and only adhesive that provides color contrast when you need it and is clear when you don’t. Bracket placement and cleanup have never been easier. The color contrast of Blugloo during bonding facilitates fast, accurate bracket placement and makes it easy to remove unwanted flash. As Blugloo warms to body temperature, the color virtually disappears, remaining clear throughout treatment. When debonding, simply introduce a short blast of cool air or water to lower the bonding surface temperature, and Blugloo turns blue again for easy and thorough cleanup.
