Gr. Hamed et R. Paul, EFFECT OF VARIOUS BONDING AGENTS ON THE SULFIDATION OF BRASS-PLATED STEEL CORDS IMMERSED IN SQUALENE MIXTURES, Rubber chemistry and technology, 70(4), 1997, pp. 541-548
Brass-plated steel cords have been immersed at elevated temperatures i
n various squalene mixtures containing sulfur curatives and commercial
ly available bonding agents. Copper sulfide growth was characterized b
y scanning electron microscopy and energy dispersive x-ray analysis. T
he bonding agents cause early sulfide growth, even prior to ''scorch,'
' but mitigate sulfide overgrowth upon humid aging. Both effects are e
xpected to improve joint durability.
