This formula produces pink rubber molds with \u003cstrong\u003eno shrinkage\u003c\/strong\u003e and outstanding reproduction of fine design details — ideal for preserving intricate wax carvings, organic models, or any original that cannot withstand conventional vulcanizing conditions.\u003c\/p\u003e\u003cp\u003eUse LiquaCast whenever you need a backup copy of a wax design, for limited production runs, or any time you cannot risk losing your original model. The rubber cures at room temperature in 16–24 hours, and each kit includes precise, detailed instructions for use.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eVacuuming is recommended for best results. If a vacuum pump is not available, good results can still be obtained by dipping the model in liquid rubber rather than pouring directly, or by brushing on a small quantity of the mixture and inspecting for bubbles before pouring the full mold.\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e Castaldo USA was sold to a company in the United Kingdom, and all Castaldo products are now manufactured in the UK.
