Product Description
Dragon Skin™ 15
Dragon Skin™ silicones are high performance platinum cure liquid silicone compounds that are used for a variety of applications ranging from creating skin effects and other movie special effects to making production molds for casting a variety of materials. Because of the superior physical properties and flexibility of Dragon Skin™ rubbers, they are also used for medical prosthetics and cushioning applications. Dragon Skin™ rubbers are also used for a variety of industrial applications and have a service temperature range of a constant -65°F to +450°F (-53°C to +232°C).
TASK™ 4
TASK™ 4 is a unique polyurethane casting resin that is very strong when cast in Ultra-Thin sections ranging from 0.03” to 0.50”(0.075cm to 1.27cm). TASK™ 4 has a very low mixed viscosity, ensuring flawless pick-up of even the finest detail. Cured plastic exhibits very low shrinkage which is why this plastic has become a favorite of prototype and design professionals throughout the world. Pot life is 20 minutes and cure time is 16 hours at 73°F/23°C.
Vibrant colors and color effects are possible by adding SO-Strong™ color tints. Fully cured models made from TASK™ 4 are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for TASK™ 4 include making prototype and architectural models, model toys, durable miniatures, ultra-thin mechanical parts and special effect props.
