Teton-Bond™ 130 Petrobond Casting Sand (10lb bag)<br>Teton-Bond™ 130 Petrobond Casting Sand (10lb bag)<br>Overview<br>Teton Supply Co™ Teton-Bond™ 130 is a high-performance Petrobond®* clay based foundry sand that is professionally formulated, produced, and quality inspected in the USA. Made with 130 Mesh Silica for general purpose use on smaller castings (up to 6").<br>Applications<br>-Molds for Precious and Non-Precious casting (non-ferrous metals including gold, silver, aluminum, brass, bronze, zinc, etc)<br>-Use as a facing sand with other sand systems such as water-bonded greensand.<br>-Backing sand for delft-clay in order to increase delft clay utilization.<br>Directions/Use Notes<br>-Sand should be riddled (broken up) prior to placing against pattern.<br>-Moderately heavy ramming or pressing is required for optimal mold performance.<br>-Appropriate mold release should be used with all patterns to avoid sticking and to maximize detail reproduction (Teton-Part™ or similar is recommended)<br>Application Notes/Troubleshooting<br>Weak Sand Molds (can't pull pattern without mold collapse)<br>-Use adequate ramming pressure. Using hands and fingers alone will not provide sufficient ramming pressure.<br>-Use quality parting/pattern compound.<br>-Use minimum of 3 degree draft on patterns.<br>-Pattern Surface finish is important. Rough patterns will require more than 3 degree draft.<br>Cold Sensitivity: Dry and Powdery Sand that does not hold form<br>-Use and store above 65F<br>-Sand may become powdery or dry if exposed to cold.<br>Regenerating Sand (how to fix dry sand that has been exposed to cold)<br>-Add a tiny amount of isopropyl alcohol to the sand using a sprayer and mix well. Generally, less than 1/2 teaspoon Alcohol required for 10lb evenly spread through the sand.<br>-Always allow alcohol to evaporate completely before attempting to use sand.<br>Excessive Smoking<br>-Allow molds to sit for sufficient time after pour to limit smoking<br>Reusing Sand/Crust<br>-Sand is mostly reusable per casting.<br>-After pour, small amount of crust is formed around the casting.<br>-This crust is two parts: 1. Black sand. 2. Grey, "crispy" sand<br>-Only the grey sand that feels "crispy" next to the casting needs to be discarded.<br>-It is normal for a sand-pile to darken with use.<br>Product Volume/Weight Info<br>-10lb of this product fills a volume of around 200 cubic inches (Approx 6"X6"X6" cube) when moderately rammed (packed).<br>*=Petrobond® is a registered trademark of Halliburton Energy Services, Inc.<br>Listing and template services provided by inkFrog<br>
