Cold silanization in the sandblasting unit

The Basic series of Renfert sandblasting units is exclusively recommended by
3M ESPE for use with ROCATEC™. This bonding system is ideal if an adhesive bond is required between a composi-
te 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, homogeneous jet flow.
