Smooth-Cast 65D Semi-Rigid Plastic Urethane Resin Kit
The Smooth-Cast Semi-Rigid line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer excellent impact resistance. 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 color pigments. 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. Because no two applications are quite the same, a small test application to determine suitability is recommended if performance of this material is in question.
