ALL-BOND 2, the original 4th Generation adhesive, is still unsurpassed in its comprehensive ability to bond to dentin, enamel, new or old composite, precious, semi-precious and non-precious casting alloys, silane-treated porcelain, and new or old amalgam. It has a dual-cured primer for higher conversion rates, and contains BISCO's own patented hydrophilic monomer (BPDM).
