Engineered specifically for the production of high-quality gold and silver pieces, this professional-grade formula is trusted by master casters and fine art studios worldwide. Whether you are producing intricate jewelry or detailed art pieces, SC20 provides the consistency and reliability required for flawless metal reproduction.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003e\u003cb data-path-to-node=\"3\" data-index-in-node=\"0\"\u003eAdvanced Formula and Innovation\u003c\/b\u003e SC20 is a premium blend of powdered silica (quartz), cristobalite, and a high-strength gypsum binder. This unique composition provides ideal thermal expansion, which is critical for maintaining the integrity of the mold during the wax setting and burnout phases. The formula is remarkably flexible, making it compatible with a diverse range of metal alloys and complex design geometries. For those casting larger items, such as figurines, the SV20 variant offers a thick-slurry version of this trusted technology to accommodate greater volume.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003e\u003cb data-path-to-node=\"4\" data-index-in-node=\"0\"\u003eSafety and Precision with BANDUST Technology\u003c\/b\u003e Health and safety are paramount in the casting environment.
