Can be used only under Amalgam. Copaliner protects the dentin and penetrates, fills, and seals the tubuli. It insulates against thermal, galvanic reaction, electrical shock, and prevents hyperemia, death of the pulp, and discoloration. Copaliner provides a strong bond and an excellent marginal seal that will extend the life of the restoration. Its non-chloroform formula is scratch-resistant and virtually insoluble in the oral environment. Over time it will develop dentinal tags for improved performance. Copaliner is ether-based with a biologically mild formula, minimizing post-operative sensitivity.
