Smooth Cast 65D ROTO Gal Kit 15.4Lb (796306)
Smooth-Cast 65D (formerly ROTO) is a low viscosity, mercury free liquid plastic that gradually builds thixotropy (becomes thicker), making it ideal for rotational casting applications. Castings will be hollow and lightweight but have the appearance of being solid, allowing you to use less material to attain the same finished look. Pot Life: 2.5 min. Demold: 10-15 mins.
Smooth Cast 65D can also be cast solid for a variety of industrial and art-related applications. Fully cured castings are semi-rigid and exhibit good impact resistance. Castings resist moisture and mild solvents and can be machined, sanded and painted. Color effects are possible by adding SO-Strong and UVO Color tints. Smooth Cast 65D is ideal for making hollow rotationally cast parts.
How do I remove release agent from my cured urethane casting if I want to prime or paint the casting?
Removing a silicone-based release agent from your cured urethane casting is not easy. The most effective way is to sand blast or bead blast the surface of your casting. However, sand blasting removes a micro thin layer of the casting's surface. If not done properly, you can damage or remove fine detail. Soap Wipe or brush the casting with a soap that has high alkali content. Cascade brand dishwashing gel is highly alkaline and also contains baking soda, which is an advantage. Solvents Wipe or brush the casting with Acetone, Toluene, Isopropyl Alcohol or Mineral Spirits. Important: follow all safety precautions when using flammable liquids. You can then prime and paint your casting.
