Rubber curative and ultra-accelerator that provides improved scorch protection, high elongation, and prevents bloom. Rubber cured with ROYALAC™ 150 will not emit nitrosamines.
ROYALAC™ 150 is an innovative curing agent and ultra-accelerator for natural and synthetic rubbers. Like most thiuram disulfide type curatives, ROYALAC™ 150 provides a fast cure rate and good aging properties. Additionally, it improves scorch safety, imparts high elongation, eliminates bloom, without producing nitrosamines.
