    In scratch chamber tests, a small piece of rubber gloves & /zinc diethyldithiocarbamate/ ZDC produced a weal greater than histamine control at 15 min. Patient used different gloves at work when test began & no urticaria appeared. ZDC seemed to be sufficiently absorbed by contact to cause immunologic urticaria & edema of eyelids.

    Rubber Compounding

    Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage.

    THE RUBBER INDUSTRY: REFLECTIONS ON HEALTH RISKS

    Reference to Fig. 1.1 will indicate that the other main health hazards likely to be encountered in rubber processing derive from exposure to dusts and fumes. Bales of natural rubber are covered in talc which is released when they are handled and cut. Talc is also a commonly used anti-stick agent, especially in tube extrusion.

    The Mechanism of Zinc(II)-Dithiocarbamate-Accelerated

    These studies have revealed that, in a three-stage process, ZDMC exhibits a unique combination of catalytic activity: (1) It mediates the reaction between sulfur and rubber. This is achieved by incorporating sulfur atoms in the zinc-dithiocarbamate ring and inducing their insertion into an allylic C−H bond via an ene-like reaction.
