Solidex Metal Photo Primer is an adhesive liquid which reliably bonds metals and Solidex Composite chemically to one another. Solidex Metal Photo Primer is compatible to the Solidex Composite System and is used as a metal bonding system. In this bonding technique, retention beads, e. g. Retention Beads (150 µm) from SHOFU, must be applied to the surface to be bonded. A further indication is the use of Solidex Metal Photo Primer in the model casting technique, e. g. in producing metal framework in combination with Solidex PO – Solidex Pink Opaque, the pink-colored opaquer.
