Properties: Curekind Retarder E/C 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. Non harmful substances formed during curing process. Mainly used in automotive rubber seal system. Dosage:0.5-1.5 phr. Same active material with DZ-01,but with higher content.
