Semi-Rigid Urethane Casting Resin
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 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™, UVO™ or Ignite™ colorants.
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.
