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™ colour tints or Ignite™ colour pigments.

These semi-rigid plastics are good for making impact resistance prototypes, abrasion resistant parts, climbing holds, foundry patterns, roller facings, vibration pads, 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.
