Latex, tin-cure silicone, sulfur clays, certain wood surfaces, newly cast polyester, epoxy or urethane rubber may cause inhibition. If compatibility between the rubber and the surface is a concern, a small-scale test is recommended. Apply a small amount of rubber onto a non-critical area of the pattern. Inhibition has occurred if the rubber is gummy or uncured after the recommended cure time has passed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBecause 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\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTo prevent inhibition, one or more coatings of a clear acrylic lacquer applied to the model surface is usually effective. Allow any sealer to thoroughly dry before applying rubber. Note: Even with a sealer, platinum silicones will not work with modeling clays containing heavy amounts of sulfur. Do a small scale test for compatibility before using on your project.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eApplying A Release Agent\u003c\/strong\u003e\u003c\/em\u003e - Although not usually necessary, a release agent will make demolding easier when pouring into or over most surfaces. \u003cstrong\u003eEase Release™ 200\u003c\/strong\u003e is a proven release agent for making molds with silicone rubber.

Follow with a light mist coating and let the release agent dry for 30 minutes.\u003c\/p\u003e\n\u003cp\u003eIf there is any question about the effectiveness of a sealer\/release agent combination, a small-scale test should be made on an identical surface for trial.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMEASURING \u0026amp; MIXING...\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eBefore you begin, pre-mix Part B thoroughly.

Your vacuum pump must pull a minimum of 29 inches of mercury (or 1 Bar \/ 100 KPa). Leave enough room in container for material expansion. Vacuum material until it rises, breaks and falls. Vacuum for 1 minute after material falls.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003ePouring\u003c\/em\u003e\u003c\/strong\u003e - For best results, pour your mixture in a single spot at the lowest point of the containment field. Let the rubber seek its level up and over the model. \u003cstrong\u003eA uniform flow will help minimize entrapped air.\u003c\/strong\u003e The liquid rubber should level off at least 1\/2” (1.3 cm) over the highest point of the model surface.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eCuring\u003c\/strong\u003e\u003c\/em\u003e - Allow the material to cure fully at room temperature (73°F \/ 23°C) before demolding. \u003cstrong\u003eSORTA Clear™ 40\u003c\/strong\u003e cures in 16 hours.

Depending on what is being cast into the mold, mold lubricity may be depleted over time and parts will begin to stick. No release agent is necessary when casting wax or gypsum. Applying a release agent such as \u003cstrong\u003eEase Release™ 200\u003c\/strong\u003e (available from Smooth-On) prior to casting polyurethane, polyester and epoxy resins is recommended to maximize mold life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eMold Performance \u0026amp; Storage\u003c\/em\u003e\u003c\/strong\u003e - The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete can quickly erode mold detail, while casting non-abrasive materials (wax) will not affect mold detail. Before storing, the mold should be cleaned with a soap solution and wiped fully dry. Two part (or more) molds should be assembled. Molds should be stored on a level surface in a cool, dry environment.\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.smooth-on.com\/msds\/files\/BD_DS_Eco_Equ_EZB_EZS_Psy_MS_OOMOO_Reb_ST_SS_Soma_Sol_Sorta.pdf\" target=\"_blank\"\u003eSDS\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.smooth-on.com\/tb\/files\/SORTA_CLEAR_SERIES_TB.pdf\" target=\"_blank\"\u003eTDS\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.smooth-on.com\/tb\/files\/FOOD_SAFE_SILICONES.pdf\" target=\"_blank\"\u003eFood Safety Certification\u003c\/a\u003e\u003c\/p\u003e","brand":"Smooth-On","offers":[{"title":"Trial Kit (2.2 lbs. \/ 1 kg.)","offer_id":48015731425595,"sku":"82644","price":53.99,"currency_code":"USD","in_stock":false},{"title":"Gallon Kit (9.9 lbs. \/ 4.49 kg.)","offer_id":48015731458363,"sku":"82661","price":180.99,"currency_code":"USD","in_stock":false},{"title":"5 Gallon Kit (49.5 lbs. \/ 22.45 kg.)","offer_id":48015731491131,"sku":"82671","price":756.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/Sorta-Clear-40-combo-1400x1050.jpg?v=1754767611","url":"https:\/\/maacaffestore.com\/products\/sorta-clear-40","provider":"The Compleat Sculptor, Inc","version":"1.0","type":"link"}
