Making a Lightweight, Strong, Hollow Casting by Rotocasting Matrix Dryve™


Matrix Dryve™ is ideal for rotational casting applications to create hollow, lightweight castings. Dryve™ can be rotationally cast either by hand or by machine. A minimum of 4 successive layers will build an adequate final thickness for strength and handle-ability (3/8” or 1 cm). The first layer is unthickened. To build interior wall thickness quickly, a small amount of Matrix™ Thickener (1.5% of powder by weight) can be added to your mix. Matrix™ Thickener slows the pot life and cure time of Dryve™. You can counteract this by adding Matrix™ Accelerator.
