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).
Smooth-Cast™ 45D
The Smooth-Cast™ Semi-Rigid line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer exceptional strength and impact resistance.
New Formulations – New Look!
Smooth-Cast™ 45D is newly reformulated with a translucent white appearance and improved physical properties. All Smooth-Cast semi rigids are now mercury free and phthalate free. These plastics are easy-to-use (mix ratio is 1A:1B by volume) and have low viscosities for minimal bubble entrapment. Vibrant colors are possible by adding SO-Strong™, UVO™ or Ignite™ colorants.
These semi-rigid plastics are good for making impact resistant prototypes, models, toys, props, climbing holds, etc.
