Product Description
Soma Foama™ 25
Soma Foama™ is a soft, two-component platinum silicone flexible foam that is versatile and easy to use. Soma Foama™ 25 is a higher density foam vs. original Soma Foama™ 15 which expands 2-3 times its original volume and develops a uniform 25 lb./cu. ft. cell structure (400 kg/m³). Vibrant colors can be achieved by adding Silc-Pig™ silicone color pigments. Cured foam is high heat resistance (will resist up to 350°F/176°C), water resistant, UV resistant and resists oxidation and ozone degradation.
KX Flex™ 60
KX Flex™ Series urethanes are fast setting flexible urethane casting elastomers that cure quickly and offer exceptional physical and performance properties including high impact resistance. KX Flex™ Series urethanes are easy to color using SO-Strong™, UVO™ or IGNITE™ colorants. KX Flex™ urethanes are phthalate free, mercury free and MOCA free.
KX Flex™ Series urethanes have a pot life of 2.5 minutes and handling time of 30 minutes (depending on mass). With Shore hardness values of 40A, 60A and 90A, this material is used for a variety of applications including fast mold making, fast model duplication, prototyping, durable miniatures, props and special effects, or making parts that are impact resistant. Fully cured castings are flexible, tough and durable.
