KX Flex™ Series – Fast Setting Urethane Casting Elastomers

KX Flex™ elastomers are fast setting two-component urethanes that cure quickly to semi-rigid, highly impact resistant elastomers. KX Flex™ urethanes are off-white when cured, which makes this plastic very easy to color using SO-Strong™, UVO™ or IGNITE™ colorants.

With Shore values of 60A or 90A, this semi-rigid plastic 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 tough and durable.
