| Accelerator ZIPPAC |
 |
ZIPPAC is a zinc-amine dithiophosphate complex dispersed in a polymer matrix.
ZIPPAC, when used in combination with thiazoles and thiurams, gives fast cure rates to ENB type EPDM's.
Compared to Akrochem's other thiophosphate accelerator, Accelerator VS, ZIPPAC provides a much faster cure.
ZIPPAC cures exhibit high modulus and low compression set, due to a high degree of crosslinking.
Vulcanizates are usually non-blooming.
Hot air aging properties are usually better than those obtained with other thiophosphate accelerators.
ZIPPAC does not form harmful nitrosoamines (Zippac forms only unstable primary amines that rapidly decompose) and is a useful accelerator in low nitrosoamine generating formulas where its high crosslink density and fast cure overcome normal problems associated with safe nitrosoamine cure systems. |
