Characteristics: Curekind Retarder E is white or light-yellow powder. Part of soluble in benzene, ethyl acetate,
slightly soluble in gasoline, insoluble in water.

Application: Excellent retarder for natural and synthetic rubber, suitable for EPDM, NBR & HNBR, obviously delay
the scorching time, but not affect the curing speed. Especially for thiuram vulcanization system, and
can be used as the second promoting agents, reduce curing time and improve production efficiency.
No pollution, not changing color ,can be used for light products. Meanwhile, can improve EPDM and
NBR the sulfurization cross linking density, improve stretch for stress, reduce the permanent
compression deformation. No harmful substances during curing process.
Mainly used in automotive rubber seal system. Dosage:0.5-1.5 phr.

Safety and Toxic: Refer to the MSDS
Storage: Store in closed containers in a cool, dry, well-ventilated place. Avoid exposure to direct sunlight.
