Super-Silicate is a specially processed form of sodium silicate blended with shakeout-assisting additives that is designed to be cured with CO2 gas. The special processing of this product gives it advantages over normal sodium silicate--namely a 1.5\/100 weight mix ratio (vs 4\/100 or more) which acts to improve surface finish due to the reduction of water mixed into the core sand.  Choosing Sand: Use with 50 to 130 mesh fineness Kiln-dried and free of organic debris Very fine sand requires a higher percentage mix (not exceeding 4%) Fine sand will likely require core vents  Curing: Use CO2 via injection, flow-through, or bagging Use minimum amount of CO2 possible for best results Always verify sand is fully cured before pouring molten metal  Yield: Up to 100lb sand per 16 FL OZ\u003c\/p\u003e","brand":"Teton Supply Co.","offers":[{"title":"Default Title","offer_id":45484653772956,"sku":"WBACSB07N35CF3D","price":28.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/9904\/0668\/files\/71XqUt2V3YL.jpg?v=1761723697","url":"https:\/\/toytooth.com\/products\/foundry-grade-sodium-silciate-core-sand-binder-16-fl-oz","provider":"Toytooth","version":"1.0","type":"link"}
