One self-etching, light-cured 1-bottle (7th-generation) bonding system. Contains no HEMA, but instead uses water and acetone solvents. No refrigeration needed unless not in use for a prolonged period of time.
The technique is simple -- just shake vigorously and then apply for 10 seconds. Evaporate the solvent with strong air and high-volume suction, and then light-cure for 10 seconds.
