Mold Star 40T 铂金硅胶
Mold Star 40T 铂金硅胶
注：产品包装可能有所不同
Mold Star 14T、19T、20T、31T 和 40T 均为易于使用的半透明铂金固化硅胶，按体积比 1A:1B 混合（无需称重工具）。其特点是粘度相对较低，且大多数应用场景无需真空脱气。Mold Star T 系列硅胶固化后形成柔软、坚固的硅橡胶，抗撕裂且长期收缩率极低。使用该系列硅胶制作的模具在您的模具库中使用寿命长，适用于浇注蜡、石膏、树脂及其他材料。通过添加 Silc Pig硅胶颜料或 Cast Magic效果粉末，可实现无限种色彩效果。
完全固化的 Mold Star 40T 符合美国联邦法规第 21 篇第 177.2600 节“重复使用橡胶制品”的要求，仅适用于与干燥食品和水性食品接触的场景。该材料已通过独立实验室测试，符合 21 CFR 177.2600(e) 中关于水性食品重复接触的水提取物限量要求。本材料不适用于与脂肪类食品的重复接触。

说明
Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Wear vinyl gloves only. Latex gloves will inhibit the cure of the rubber. Mixing containers should have straight sides and a flat bottom. Mixing sticks should be flat and stiff with defined edges for scraping the sides and bottom of your mixing container.
Store and use material at room temperature (73°F/23°C). Warmer temperatures will drastically reduce working time and cure time. Storing material at warmer temperatures will also reduce the usable shelf life of unused material. These products have a limited shelf life and should be used as soon as possible.
Cure Inhibition - Addition cured silicone rubber may be inhibited by certain contaminants in or on the pattern to be molded resulting in tackiness at the pattern interface or a total lack of cure throughout the mold. Latex, sulfur clays, certain wood surfaces, newly cast polyester, epoxy, tin cure 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.
Even with a sealer, Mold Star™ 14T, 19T, 20T 31T or 40T will not cure against surfaces containing sulfur. If you are not sure if your clay contains sulfur, do a small compatibility test before using for an important project.
Applying A Release Agent - Although not usually necessary, a release agent will make demolding easier when casting into most surfaces. Ease Release™ 200 is a proven release agent for releasing silicone from silicone or other surfaces. Mann Ease Release™ products are available from Smooth-On or your Smooth-On distributor. 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.
MEASURING & MIXING...
Stir Part A and Part B thoroughly before dispensing. After dispensing required amounts of Parts A and B into mixing container (1A:1B by volume or weight), mix thoroughly making sure that you scrape the sides and bottom of the mixing container several times.
Optional... Vacuum Degassing - Although not necessary, vacuum degassing helps eliminate any entrapped air in pourable silicone rubber. After mixing parts A and B, vacuum material at 29 inches of mercury, making sure that you leave enough room in container for product expansion.
POURING, CURING & PERFORMANCE...
Pouring - For best results, pour your mixture in a single spot at the lowest point of the containment field. Let the rubber seek its own level. A uniform flow will help minimize entrapped air. If using as a mold material, the liquid rubber should level off at least 1/2” (1.3 cm) over the highest point of the model surface.
Curing - Allow rubber to cure as prescribed at room temperature (73°F/23°C) before demolding. Do not cure rubber where temperature is less than 65°F/18°C.
Heat Curing - Time to demold can be reduced with mild heat. Example: After pouring Mold Star™ 14T, 19T, 20T 31T or 40T at room temperature, place the mold in a hot box or industrial oven at 140°F (60°C). This may reduce the demold time substantially. Note - time will vary depending on mold thickness.
Making a Brush On Mold? - Mold Star™ T Series silicones can be thickened with Thi-Vex™ thickener for brush-on application and effects. Maximum recommended loading rate of Thi-Vex™ is 2 parts (2% of part A). Do not use other Mold Star™ Series silicones for brush on mold making.
Mold Performance & Storage - The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials 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.
