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™ colourants.
These semi-rigid plastics are good for making impact resistant prototypes, models, toys, props, climbing holds, etc.
NOTE: Smooth-Cast™ 57D and Smooth-Cast™ 65D are also suitable for rotational casting applications. Do not use other Smooth-Cast™ semi-rigid plastics for roto casting.
