These rigid urethane casting resins differ only in working and demold times. Both have high compressive and flexural strength. Fully cured castings are tough, machinable and paintable. Color effects are possible by adding pigment dispersions. They resist moisture and mild solvents. SC 385 is ideal for making industrial production parts, foundry patterns, vacuum forming molds, and some ceramic applications.
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 castingÕs 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.
