With different hardnesses to choose from, \u003cstrong\u003eSmooth-Sil™\u003c\/strong\u003e products offer tremendous versatility and are suitable for making production molds of any configuration, large or small. These silicones exhibit good chemical, abrasion and heat resistance. Materials such as plasters, concrete, wax, low-melt metal alloys or resins (urethane, epoxy or polyester) can then be cast into these silicone rubbers without a release agent.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shoplightspeed.com\/shops\/606431\/files\/50958871\/ss940food.png\" alt=\"\" width=\"600\" height=\"320\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmooth-Sil™\u003c\/strong\u003e Platinum Silicones are used for rapid prototyping, wax casting (foundries and candle makers), architectural restoration and for casting concrete. \u003cstrong\u003eSmooth-Sil™ 940, 950 \u0026amp; 960 are suitable for food related applications. \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shoplightspeed.com\/shops\/606431\/files\/50959022\/smoothsilspecs.png\" alt=\"\" width=\"948\" height=\"379\"\u003e\u003c\/p\u003e\n\u003cp\u003eInstructions\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eSafety\u003c\/strong\u003e\u003c\/em\u003e - Use in a properly ventilated area (“room size” ventilation).

Latex, sulfur clays, certain wood surfaces, newly cast polyester, epoxy, tin silicone rubber or urethane rubber my 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. To 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEven with a sealer, Smooth-Sil™ 960 \u003cem\u003ewill not\u003c\/em\u003e\u003c\/strong\u003e \u003cstrong\u003ecure against surfaces containing sulfur.

Mann Ease Release™ products are available from Smooth-On or your Smooth-On distributor. \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\u003e\u003cem\u003e\u003cstrong\u003eMEASURING \u0026amp; MIXING...\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003eBefore you begin, pre-mix Part A and Part B thoroughly. Mix ratio is 100A : 10B by weight. \u003cstrong\u003eUsing a gram scale\u003c\/strong\u003e, dispense required amounts of parts A and B into a mixing container and mix for 3 minutes. Scrape the sides and bottom of the container several times. After mixing parts A and B, vacuum degassing is recommended to eliminate any entrapped air in liquid rubber. 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\u003cem\u003e\u003cstrong\u003ePOURING, CURING \u0026amp; PERFORMANCE\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003ePouring \u003c\/strong\u003e\u003c\/em\u003e- For best results, pour your mixture in a single spot at the lowest point of the containment field.

Example: After pouring \u003cstrong\u003eSmooth-Sil™ 960\u003c\/strong\u003e at room temperature, place the mold in a hot box or industrial oven at 140°F (60°C). This will reduce the demold time.\u003cbr\u003e\u003cstrong\u003eNote\u003c\/strong\u003e - time will vary depending on mold thickness.\u003c\/p\u003e\n\u003cp\u003eAdding an appropriate amount of\u003cstrong\u003e Plat-Cat™ \u003c\/strong\u003ecure accelerator will also reduce demold time. The pot life and cure times can be extended using \u003cstrong\u003eSlo-Jo™\u003c\/strong\u003e cure retarder.

Casting abrasive materials can quickly erode mold detail, while casting non-abrasive materials such as 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 href=\"https:\/\/www.smooth-on.com\/msds\/files\/BD_DS_Eco_Equ_EZB_EZS_Psy_MS_OOMOO_Reb_ST_SS_Soma_Sol_Sorta.pdf\" rel=\"noopener\" target=\"_blank\"\u003eSDS\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/www.smooth-on.com\/tb\/files\/FOOD_SAFE_SILICONES.pdf\" rel=\"noopener\" target=\"_blank\"\u003eFood Safe Bulletin\u003c\/a\u003e\u003c\/p\u003e","brand":"Smooth-On","offers":[{"title":"940 Trial Kit (2.2 lbs. \/ 1 kg.)","offer_id":48033081557307,"sku":"81244","price":44.99,"currency_code":"USD","in_stock":false},{"title":"940 Gallon Kit (11 lbs. \/ 4.99 kg.)","offer_id":48033081590075,"sku":"81261","price":170.99,"currency_code":"USD","in_stock":true},{"title":"950 Trial Kit (2.2 lbs. \/ 1 kg.)","offer_id":48033081622843,"sku":"83544","price":44.99,"currency_code":"USD","in_stock":false},{"title":"950 Gallon Kit (11 lbs. \/ 4.99 kg.)","offer_id":48033081655611,"sku":"83561","price":172.99,"currency_code":"USD","in_stock":true},{"title":"960 Trial Kit (2.2 lbs. \/ 1 kg.)","offer_id":48033081688379,"sku":"79741","price":44.99,"currency_code":"USD","in_stock":false},{"title":"960 Gallon Kit (11 lbs. \/ 4.99 kg.)","offer_id":48033081721147,"sku":"79761","price":173.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/Smooth-Sil-940-trial-1400x1050.jpg?v=1754770190","url":"https:\/\/maacaffestore.com\/products\/smooth-sil-food-safe-series","provider":"The Compleat Sculptor, Inc","version":"1.0","type":"link"}
