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, a “barrier coat” of clear acrylic lacquer sprayed directly onto the pattern is usually effective. Allow to thoroughly dry. Although not usually necessary, a release agent will make demolding easier when casting into or over most surfaces. \u003cstrong\u003eEase Release™ 200\u003c\/strong\u003e is a proven release agent for making molds with silicone rubber and for releasing new silicone from cured silicone.

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 \/ \u003c\/strong\u003e\u003c\/em\u003e\u003cem\u003e\u003cstrong\u003eCuring \/ Post Curing\u003c\/strong\u003e \u003c\/em\u003e\u003cem\u003e -\u003c\/em\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. A uniform flow will help minimize entrapped air. The liquid rubber should level off at least 1\/2” (1.3 cm) over the highest point of the model surface. Allow the mold to cure overnight (at least 16 hrs) at room temperature (73°F\/23°C) before demolding. Post curing the mold an additional 4 hours at 150°F (65°C) will eliminate any residual moisture and alcohol that is a byproduct of the condensation reaction that can inhibit the cure of some urethane resins and rubbers. Allow mold to cool to room temperature before using. Do not cure rubber where temperature is less than 65°F\/18°C.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThickening and Thinning Mold Max™ Silicones - \u003c\/strong\u003e\u003c\/em\u003e\u003cstrong\u003eTHIVEX™ \u003c\/strong\u003eis made especially for thickening Smooth-On’s \u003cstrong\u003eMold Max™ 20\u003c\/strong\u003e silicone for vertical surface application (making brush-on molds). Different viscosities can be attained by varying the amount of \u003cstrong\u003eTHI-VEX™\u003c\/strong\u003e. Apply a thin coat of rubber. Wait for rubber to become “tacky” before applying next coat. Final mold thickness should be at least 3\/8” (1 cm). Allow rubber to cure overnight before applying support shell. \u003cstrong\u003eSilicone Thinner™\u003c\/strong\u003e is a non-reactive silicone fluid that will lower the mixed viscosity of tin cure (condensation) or platinum cure (addition) silicone rubber products. It is not recommended to exceed 10% by weight of total system (A+B).\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAccelerating Mold Max™ Silicones\u003c\/strong\u003e\u003c\/em\u003e - \u003cstrong\u003eAccel-T™\u003c\/strong\u003e silicone rubber accelerator will accelerate the cure time of \u003cstrong\u003eMold Max™ 20\u003c\/strong\u003e silicone rubber. Note: working time is reduced in proportion to the amount of \u003cstrong\u003eAccel-T™\u003c\/strong\u003e added.

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\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/www.smooth-on.com\/msds\/files\/823A-231B.pdf\" target=\"_blank\"\u003eSDS\u003c\/a\u003e\u003c\/p\u003e","brand":"Smooth-On","offers":[{"title":"Trial Kit (2.2 lbs. \/ 1 kg.)","offer_id":47360477364539,"sku":"81644","price":36.99,"currency_code":"USD","in_stock":false},{"title":"Gallon Kit (11 lbs. \/ 4.99 kg.)","offer_id":47360477397307,"sku":"81661","price":129.99,"currency_code":"USD","in_stock":true},{"title":"5 Gallon Kit (55 lbs. \/ 24.95 kg.)","offer_id":47360477430075,"sku":"81671","price":514.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/moldmax20combo.jpg?v=1710987394","url":"https:\/\/maacaffestore.com\/products\/mold-max-20","provider":"The Compleat Sculptor, Inc","version":"1.0","type":"link"}
