OOMOO™ 25

OOMOO™ 25

无需真空脱气 - 无需秤-易于使用 OOMOO™25 是易于使用的锡固化硅胶,具有方便的1:1体积混合比(不需要秤)。它具有低粘度,便于混合和浇注。无需真空脱气。产品在室温下固化时收缩率可以忽略不计。 OOMOO™25 具有15分钟的操作时间和75分钟的固化时间。
对于新手模具制造商 -OOMOO™硅胶没有很好的抗撕裂强度。它们适用于制作简单的一块或两块模具。如果您需要高撕裂强度的硅胶,推荐使用Mold Max™硅胶。
OOMOO™25 适用于各种艺术相关和工业应用场合,包括制作用于雕塑和原型复制的一块和两块模具,浇注石膏、树脂和蜡。OOMOO™硅胶也适用于电气灌封和封装应用。

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.

Store and use material at room temperature (73°F/23°C). 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.Premix Parts A and B thoroughly before using.

Cure Inhibition - 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. 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. Materials found to cause cure inhibition include sulfur-based modeling clays and latex rubber.

To prevent inhibition apply a sealing agent . . . apply a “barrier coat” of clear acrylic lacquer sprayed onto the clay surface.

Applying A Release Agent - Although not usually necessary, a release agent will make demolding easier when pouring into or over most surfaces. Ease Release™ 200 is a proven release agent for making molds with silicone rubber and for releasing new silicone from cured silicone. 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 - Before you begin, pre-mix Parts A and B thoroughly. After dispensing equal amounts of Parts A and B into mixing container, mix thoroughly for 3 minutes making sure that you scrape the sides and bottom of the mixing container several times. Mixture should have a uniform color with no color streaks. If you observe color streaks, continue mixing until they are eliminated.

Pouring – 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.

Curing – Allow to cure for 75 minutes 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 which is a by product of the condensation process and may inhibit some resins. Allow mold to cool to room temperature before using. Do not cure rubber where temperature is less than 65°F/18°C.

Using The Mold – No release agent is necessary when casting wax or gypsum. Applying a release agent (Ease Release™ 200) prior to casting polyurethane, polyester and epoxy resins is recommended to prevent sticking and mold degradation.

Mold Performance & Storage – The physical life of the mold depends on how you use it (materials cast, frequency, etc.). Casting abrasive materials such as concrete will 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.
