Alpha-Bond® is a single-component acetone-based adhesive with a dual-cure activator (sold separately) that is designed to bond to multiple substrates for direct and indirect bonding methods. It contains the hydrophilic monomer PMGDM, which allows it to penetrate tubules, intertubules, and peritubular dentin. Use the adhesive labeled bottle for a single-step light cure adhesive. You may confidently bond to self-cure composites and regions inaccessible to light by combining the dual cure activator with the adhesive.
