Smooth Cast Semi-Rigids
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. Smooth-Cast 45D, 60D and 61D are newly reformulated with a
translucent white appearance and improved physical properties. All Smooth-Cast semirigids 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® color tints or Ignite® color 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 65D are also suitable for rotational casting applications. Do not use other Smooth-Cast®
semirigid plastics for roto casting.
