Brueggemann TP 1862 is a combination of novolak-based resin along with a zinc-based catalyzing additive that additionally allows the elimination of cobalt and cobalt salts from steel-cord adhesion mixtures without sacrificing vulcanization activity, mechanical properties, and adhesion characteristics.Removing cobalt and resorcinol from adhesion mixturesSteel-cord adhesion mixtures are commonly used in tires and other applications such as hoses or conveyor belts.In such mixtures, state-of-the-art technology uses systems containing cobalt salts as catalysts or co-accelerators and adhesion promotors, as well as resorcinol resins to achieve desired mechanical properties. As both cobalt and cobalt salts, on one hand, and resorcinol, or resorcinol-based resins, on the other hand, are deemed to be problematic from an environmental safety and health (ESH) point of view, it is worthwhile finding a solution to reduce or even eliminate such critical substances from modern rubber mixtures. The elimination of resorcinol is already realized by a novolak-based reinforcing resin. Highlights of TP 1862:No cobaltNo resorcinolHigh adhesion to steelHigh mechanical propertiesLow zinc and heavy metal content
