en
ROCATEC™� This bonding system is ideal if an adhesive bond is required between a composite and a
dental material (metal, acrylic, porcelain, zirconia porcelain)�
Advantage:
The surface film is applied cold, preventing thermal loading of metal frameworks and consequently the
risk of distortion� All units in the Basic series can be used for ROCATEC™ due to their regular, homoge-
neous jet flow.
