Reprorubber® putty is a two component, addition cured, platinum catalyzed, hydrophobic vinyl polysiloxane. It is a hand mixed to obtain a uniform mixture. It may be used to reproduce surface characteristics. It is able to reproduce surfaces down to submicron particles or scratches. It is cured at room temperature. However, warmer temperatures accelerate the setting time and cooler temperatures slow the setting time.
