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

Zinc Oxide RAC by Brüggemann is a type of active zinc oxide that is produced through a special precipitation process. It is suitable for use in the vulcanization of a variety of rubber types, including:Natural rubber (NR)Styrene-butadiene rubber (SBR)Isoprene rubber (IR)Nitrile rubber (NBR)The product has excellent vulcanization properties due to its gentle thermal treatment and chemical origin. It is known for its high specific surface area, which enables it to provide excellent mechanical properties even when used in smaller amounts compared to traditional zinc oxides. Zinc Oxide RAC has a shelf life of 12 months.
