Procad Barrier Liquid for Resin Casting - TC0456

Procad Barrier Liquid for Resin Casting by GRS

Procad has been developed, tested and approved for two applications when producing resin pieces or patterns from Cadcam Rapid Prototype printers. Resin pieces or patterns are produced to either manufacture rubber moulds using the resin pattern as master pieces or for producing trees to direct cast the resin patterns or pieces.

For both of these applications we have been able use Procad to over come problems when producing rubber moulds or when direct casting the resin pieces or patterns

The most common problem when direct casting of resin pieces or patterns is rough surfaces and inclusions. Resin expands and boils disturbing the surface of the investment powder creating the rough surfaces. The resin can also migrate into the investment powder or the opposite, by the investment migrating into the resin surface causing rough surfaces or inclusions.

To overcome this the resin piece can be dipped in Procad between 5 to 10 times to avoid this. The amount of time a resin pieces can be dipped in Procad depends on the design and it is recommended to reduce the dipping if the piece is small, contains tiny holes, recesses for stone setting or is filigree in design.

You can invest with slightly warmer water, the warmer the slurry is when investing the quicker the set time will be. We advise only a few degrees warmer than what you regularly use, as it may set too quick.
