Ecoflex™ 00-20 FAST /36.28kg

Les caoutchoucs Ecoflex ™ sont des silicones catalysées en platine qui sont polyvalents et faciles à utiliser.

Les caoutchoucs Ecoflex ™ sont mélangés 1A: 1B en poids ou en volume et guéri à la température ambiante avec un retrait négligeable.
La faible viscosité assure un mélange facile et une dé-air. Le caoutchouc durci est très doux, très fort et très "extensible", étirant plusieurs fois sa taille d'origine sans se déchirer et rebondira à sa forme d'origine sans distorsion.

Certifié sans danger pour la peau - Le matériau est sans danger pour la peau et certifié par un laboratoire indépendant selon la norme OCDE TG 439.

Caractéristiques

Les caoutchoucs Ecoflex ™ sont translucide et peuvent être pigmentées avec des pigments Silc Pig ™ pour créer une variété d'effets de couleur. Vous pouvez également ajouter le silicone Tinner ™ de Smooth-ON pour réduire encore la viscosité. L'épaississant de silicone THI-VEX ™ peut être ajouté en poids aux silicones ECOFLEX ™ pour des applications à la brosses.

Les caoutchoucs Ecoflex ™ conviennent à une variété d'applications comprenant des appareils prothétiques, un amorti pour les orthèses et des applications d'effets spéciaux (en particulier dans les animatroniques où le mouvement répétitif est requis).

Ecoflex ™ 00-20 FAST a une durée de vie du pot de 20 minutes - temps de durcissement 1h30 - Elongation 845% - Dureté Shore 00-20 - Couleur Translucide

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.

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.

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.

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 use 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 & 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 in liquid rubber. Your vacuum pump must pull a minimum of 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.

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 1.3 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 Ecoflex™ 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 Ecoflex™ Silicones - Smooth-On’s Silicone Thinner™ will lower the viscosity of Ecoflex™ silicones 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).

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.
