After an adequate wall thickness is attained inside the mold, the result is a cured hollow casting that is semi-rigid and highly impact resistant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUse as a Casting Resin\u003c\/strong\u003e – \u003cstrong\u003eSmooth-Cast™ 57D\u003c\/strong\u003e can also be used as a casting resin for making solid, semi-rigid castings that are tough and durable.\u003c\/p\u003e\n\u003cp\u003eMix ratio is 1A:1B by volume. Working time is 3 minutes, demold time is 30 minutes and full cure properties are attained after 24 hours. Color is white translucent and the material is very easy to color with \u003cstrong\u003eSO-Strong™\u003c\/strong\u003e, \u003cstrong\u003eUVO™\u003c\/strong\u003e or \u003cstrong\u003eIgnite™\u003c\/strong\u003e colorants.

This material has a limited shelf life and should be used as soon as possible. Mixing should be done in a well-ventilated area. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. All liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal, glass or plastic. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying A Release Agent\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003eA release agent is necessary to facilitate demolding when casting into or over many surfaces. Use a release agent made specifically for mold making and casting such as Mann’s \u003cstrong\u003eEase Release™ 200\u003c\/strong\u003e available from Smooth-On. A liberal coat of release agent should be applied onto all surfaces that will contact the plastic.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIMPORTANT:\u003c\/strong\u003e To ensure thorough coverage, apply release and brush with a soft brush over all surfaces. Follow with a light mist coating and let the release agent dry for 30 minutes.\u003c\/p\u003e\n\u003cp\u003eSmooth-On silicone rubber molds usually do not require a release agent unless casting silicone into the mold. Applying a release agent will prolong the life of the mold.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMixing\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cstrong\u003ePre-Mix PART-A and PART-B Thoroughly Before You Begin. \u003c\/strong\u003eAfter pre-mixing both parts, dispense required amounts of Parts A and B into mixing container and mix thoroughly. Stir for at least 30 seconds, making sure that you scrape the sides and bottom of the mixing container several times.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eCuring\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Use this product with at least room size ventilation or in proximity to a forced outlet air vent and do not inhale\/breath fumes. Fumes, which may be visible with a significant mass concentration, will quickly dissipate with adequate ventilation. Castings with significant mass may be hot to the touch and irritate skin immediately following cure. Let casting cool to room temperature before handling.\u003c\/p\u003e\n\u003cp\u003eDemold time of the finished casting depends on mass and mold configuration. Low mass or thin-walled castings will take longer to cure than castings with higher mass concentration.\u003c\/p\u003e\n\u003cp\u003eIf making rotational or hollow castings, backfilling with a rigid foam (Foam-iT! 5 or other) will provide lightweight reinforcement. Foam backfilling is recommended if castings will be subjected to temperatures above 85°F \/ 30°C.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003eCured castings are semi-rigid and impact resistant. They resist moisture, mild heat, solvents (intermittent contact) and can be primed\/painted or bonded to other surfaces (any release agent must be removed) using \u003cstrong\u003eUrebond\u003c\/strong\u003e or similar flexible adhesive. If machining material, wear breathing protection. Unpainted castings may discolor in proportion to duration and intensity of exposure to UV light.\u003c\/p\u003e\n\u003cp\u003eIf suitability of any Smooth-On material is in question for your application, a small scale test is recommended before using for an important project.\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.smooth-on.com\/msds\/files\/SC_300_300Q_320_380_45D_60D_61D_65D_66D_ONYX.pdf\" target=\"_blank\"\u003eSDS\u003c\/a\u003e\u003c\/p\u003e\n","brand":"Smooth-On","offers":[{"title":"Trial Kit (2.07 lbs. \/ 0.94 kg.)","offer_id":48429572817211,"sku":"79644","price":28.99,"currency_code":"USD","in_stock":true},{"title":"2 Gallon Kit (16.6 lbs. \/ 7.53 kg.)","offer_id":48429572849979,"sku":"79661","price":145.99,"currency_code":"USD","in_stock":true},{"title":"10 Gallon Kit (83 lbs. \/ 37.65 kg.)","offer_id":48016031613243,"sku":"79671","price":594.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/Smooth-Cast-57D-gallon-1400x1050.jpg?v=1754770899","url":"https:\/\/maacaffestore.com\/products\/smooth-cast-57d-series","provider":"The Compleat Sculptor, Inc","version":"1.0","type":"link"}
