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.
New Formulations – New Look! Smooth-Cast 45D, 60D and 61D are newly reformulated with a translucent white appearance and improved physical properties.
All Smooth-Cast semi-rigids 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.
Smooth-Cast® 65D has a unique gradual cure profile that makes it ideal for rotational casting applications.
