Directions for Use

Mixing:

• In order to achieve a homogenous consistency, divide the measured quantity of powder into 4 portions (1/2 1/4 1/8 1/8).
• Beginning with the smallest quantity, stroke the powder into the measured liquid within 90 seconds.
• The filling consistency has been reached when on lifting the spatula, the peak drawn out forms a small hook and does not sink back into the paste.
• The fixation consistency has been reached when the peak formed on lifting the spatula slowly falls back into the paste.
• Discard remaining powder or impure liquid.
• Mixing Time: 90 seconds

Special Information:

• The mixed cement should never be applied directly onto dentine near to pulp or onto exposed pulp.
• Irritations of the pulp may occur following the cementing and in the case of the mixture being used for cavity lining.
• The cement must be applied to the dry tooth surface and must set without contact to moisture.
• Close containers immediately after removing material.
• The liquid contains phosphoric acid and is corrosive. In the event of accidental eye contact, rinse immediately with large quantities of water.
