Urethane is a type of synthetic material commonly used in various industries, including automotive and aviation. In the context of art or sculpting, urethane refers to sculptures made from this material. Urethane sculptures are typically created using molds that are made from original sculptures or other objects. The liquid urethane is then poured into these molds and allowed to cure before being removed from the mold. Once cured, urethane sculptures can be painted or finished in a variety of ways to achieve different effects. Urethane sculptures are often used for commercial purposes such as advertising or display pieces due to their durability and ability to withstand weather conditions.
