Urethane casting resins can create molds, parts, prototypes, and tools of varying hardness, from soft rubber to hard plastic. They are built for durability and strength.
- The softer Shore A urethanes will deliver pliable, impact-resistant parts or flexible molds for harder urethanes with negative angles.
- Shore D urethanes will deliver harder, more rigid parts, capable of holding surface details for superior cosmetics.
Casting Urethanes are sold as two-part kits that are meant to be mixed and poured into open casts and closed molds. Note that mixing ratios and pot life vary widely. Urethanes are also particularly sensitive to moisture before cure, so avoid using paper tubs and wooden stirrers during the mixing stage.

- The 40 Shore A casting resin is soft with the approximate hardness of a rubber band.
- The 60 Shore A casting resin is firmer, about as hard as a car tire.
