Description
Bosworth Zinc Phosphate Cement
Copaliner cavity varnish and sealant protects the dentin and penetrates, fills, and seals
the tubuli. It insulates against thermal, galvanic, and 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. CAN ONLY BE USED
UNDER AMALGAM
are easily irritated. Adheres to tooth structure in the presence of moisture. Not to
be used for implants.
Tips: Regular set has a greater than 15 minute slab set, but a shorter in the mouth
set of 10-15 minutes. The fast set has a 10-15 minute slab set, but a faster in the
mouth set of 4-8 minutes. Film thickness 25 microns.Zinc Phosphate Cement is specially blended to mix smooth and complete. This cement has
excellent bonding strength and works well for crowns, inlays, fixed bridgework, orthodontic
bands, and temporary fillings. Powder available in yellow or light yellow.
Tips: As the amount of powder incorporated into the mix is increased, the strength increases.
Incorporate the powder incrementally. If a large amount of powder is mixed into the liquid all
at once, the temperature at the site of the reaction becomes higher, resulting in an increased
reaction time and loss of control of the consistency. For orthodontic bands, a heavy consistency
will produce greater film thickness, which is important for band retention.
