Product Description

Mold Star™ 15 SLOW

Mold Star™ rubbers are easy to use platinum silicones which are mixed 1A:1B by volume (no weighing scale necessary). Mold Star™ silicones feature relatively low viscosities and vacuum degassing is not required for most applications. The pot life of Mold Star™ 15 SLOW is 50 minutes and cure time is 4 hours at room temperature.
