Dragon Skin™ 30 /36,28 kg

Les silicones Dragon Skin™ sont des composés de silicone liquides à durcissement platine hautes performances qui sont utilisés pour une variété d'applications allant de la création d'effets de peau et d'autres effets spéciaux de films à la fabrication de moules de production pour le moulage de divers matériaux. En raison des propriétés physiques supérieures et de la flexibilité des caoutchoucs Dragon Skin®, ils sont également utilisés pour les prothèses médicales et les applications de rembourrage. Les caoutchoucs Dragon Skin® sont également utilisés pour une variété d'applications industrielles et ont une plage de températures de service constante de -53 °C à +232 °C

Caractéristiques

Matériau d'effets spéciaux polyvalent -Doux, super résistant et extensible, Dragon Skin™ est utilisé dans le monde entier pour créer des effets spectaculaires sur la peau et les créatures. Un nombre infini d'effets de couleur peut être obtenu en ajoutant des pigments de silicone Silc Pig™ ou des poudres à effets Cast Magic™.

Facile à utiliser – Les silicones Dragon Skin™ sont mélangés 1A:1B en poids ou en volume. Le caoutchouc liquide peut être dilué avec du Silicone Thinner™ ou épaissi avec du THI-VEX™. Le caoutchouc durcit à température ambiante 23°C avec un retrait négligeable. Le dégazage sous vide est recommandé pour minimiser les bulles d'air dans le caoutchouc durci.

Rapport de mélange 1A:1B - Durée de vie en pot 45 minutes - temps de durcissement 16 heures - dureté Shore 30 A - couleur transparent - Elongation@rupture 364 %

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 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-cure 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, 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.

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. 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.

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.

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. Mann Ease Release™ products are available from Form X

IMPORTANT: To ensure thorough coverage, lightly brush the release agent with a soft brush over all surfaces of the model. Follow with a light mist coating and let the release agent dry for 30 minutes.

If 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.

Measuring and Mixing - Before you begin, pre-mix Part B thoroughly. After dispensing required amounts of Parts A and B into mixing container (1A:1B by volume or weight), mix thoroughly for 3 minutes making sure that you scrape the sides and bottom of the mixing container several times. After mixing parts A and B, vacuum degassing is recommended to eliminate any entrapped air. Vacuum material for 2-3 minutes ( 0,98 bar), making sure that you leave enough room in container for product volume expansion.

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 1.3 cm over the highest point of the model surface.

Curing / Post Curing - Allow rubber to cure as prescribed at room temperature 23°C before demolding. Do not cure rubber where temperature is less than 18°C. Optional: Post curing the mold will aid in quickly attaining maximum physical and performance properties. After curing at room temperature, expose the rubber to 80°C for 2 hours and 100°C for one hour. Allow mold to cool to room temperature before using.

If Using As A Mold - When first cast, silicone rubber molds exhibit natural release characteristics. 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 Ease Release™ 200 (available from Form X) prior to casting polyurethane, polyester and epoxy resins is recommended to prevent mold degradation.

Thickening Dragon Skin™ Silicones - THI-VEX™ is made especially for thickening Smooth-On’s silicones for vertical surface application (making brush-on molds). Different viscosities can be attained by varying the amount of THI-VEX™.

Thinning Dragon Skin™ Silicones - Smooth-On’s Silicone Thinner™ will lower the viscosity of Dragon Skin™ for easier pouring and vacuum degassing. A disadvantage is that ultimate tear and tensile are reduced in proportion to the amount of Silicone Thinner™ added. It is not recommended to exceed 10% by weight of total system (A+B).

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 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.
