{"product_id":"castin-craft-mc-poly-resin-molds","title":"MC Poly Resin Molds","description":"\u003cp\u003eChemical-resistant polypropylene construction means these molds handle repeated pours without degrading or warping. No mold release needed, cast your resin, let it cure, and pop out finished pieces cleanly. The material's inherent release properties save preparation time and eliminate residue buildup that compromises detail over multiple uses.\u003c\/p\u003e\n\u003cp\u003eSmooth interior surfaces produce glass-like finishes straight from the mold, minimizing post-cure polishing on dimensional pieces. Sharp edges and perpendicular sides maintain geometric precision, particularly valuable when creating multiples that need to match or components that must fit together. The rigid walls resist flexing during cure, preventing distortion in thicker pours.\u003c\/p\u003e\n\u003cp\u003eThese molds excel at embedding work, flowers, insects, photographs, found objects, where you need clarity around inclusions and predictable positioning. The consistent wall thickness ensures even curing, reducing the risk of soft spots or incomplete polymerization that plague thinner, flexible molds. Build a collection around the shapes you cast most frequently, confident each mold will deliver dozens of consistent pulls before showing wear.\u003c\/p\u003e","brand":"Castin' Craft","offers":[{"title":"2 3\/8 in. dia. x 1 1\/8 in. \/ 2 1\/2 oz. \/ circle","offer_id":48100143268069,"sku":"36692","price":5.34,"currency_code":"USD","in_stock":false},{"title":"3 in. x 6 in. x 1 1\/16 in. \/ 9 oz. \/ rectangular","offer_id":48100143300837,"sku":"37588","price":5.36,"currency_code":"USD","in_stock":false},{"title":"2 in. x 1 1\/2 in. x 1 in. \/ 2 oz. \/ rectangular","offer_id":48100143333605,"sku":"49871","price":5.34,"currency_code":"USD","in_stock":true},{"title":"3 in. dia. x 1 3\/8 in. \/ 4 oz. \/ dome shaped","offer_id":48100143366373,"sku":"55446","price":6.06,"currency_code":"USD","in_stock":true},{"title":"2 1\/8 in. x 3 1\/4 in. x 1 1\/8 in. \/ 4 oz. \/ rectangular","offer_id":48100143399141,"sku":"77028","price":5.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s36692.jpg?v=1769785419","url":"https:\/\/www.texasart.mom\/products\/castin-craft-mc-poly-resin-molds","provider":"Texas Art Supply","version":"1.0","type":"link"}
