MOLD CONSTRUCTION:

The composites approach to mold construction uses TC-1651 as a binder for SC-125 Aluminum Granules. This mixture is cast behind a high temperature surface coat, TC-1611 or TC-1618. This combination provides several benefits. The TC-1611 or TC-1618 surface coat provides exceptional durability, and the aluminum granule addition to the TC-1651 provides increased heat conductivity and allows pouring of large masses. In addition, this method reduces cost. Generally, the SC-125 Aluminum Granule is added at the rate of 60-80 parts by weight to 100 parts by weight mixed resin and hardener. Larger amounts of aluminum granules are added when making vacuum form molds, casting molds, foam molds, and other low pressure compression type molds. When casting TC-1651 without the addition of aluminum granules, the thickness of the cast should generally be limited to 3" to control shrinkage or excess exotherm.

Use in a well-ventilated area. Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged contact on the skin may cause an allergic reaction. Eye protection is extremely important. Always use approved safety glasses or goggles when handling this product.
