It uses Smooth-On's Libra catalyst system to keep mixed material stable while allowing ample working time. The compound accepts Silc Pig colorants, responds well to vacuum degassing, and cures at room temperature without specialized heat.\u003c\/p\u003e\n\n\u003ch3\u003eHow long will I have to work with Mould Max 30 after mixing?\u003c\/h3\u003e\n\u003cp\u003eAfter combining base and catalyst, Mould Max 30 provides roughly 45 minutes of pot life—enough for most small to medium pours and for removing bubbles before cure.
