Zeonet system

The Zeonet system does provide very good compression set without post-cure, good bin stability, reasonably fast cure rates, and it may be cured in open steam. The vulcanizates have good water and corrosion resistance. 

Transmission Oil Cooler Hose compounds are shown in Table 5.24 in which two non-post-cure systems are given. Both the NPC-25 and Zeonet system provides low compression set without post-cure. The temperature of the NPC-25 compound during processing must NOT exceed 85°C, as measured in the stock. During vulcanization, a moisture barrier such as Mylar film should be wrapped on under the nylon tape. The Zeonet cure mechanism also does not require a post-cure and it has the added advantage that it may be used in open steam without a moisture barrier. 

Epoxy side cure sites offer a reduction in mold and metal corrosion and are better for water resistance [7]. Two main cure systems are available for these products, Zeonet A, BF, and HyTemp SR50 combination as well as ammonium benzoate.
