  • Method for modifying the surface of an elastomer product
    Patent number: 9894946
    Abstract: The invention relates to a method for modifying the surface of an elastomer product with unsaturated carbon-carbon bonds, in particular a glove, whereby the unsaturated carbon-carbon bonds in the region of the surface are at least partially saturated by a photochemical reaction with at least one thiol or by applying or dipping to apply a layer of latex to at least certain regions of the surface of the elastomer product, the unsaturated carbon-carbon bonds of which in the region of its surface are at least partially saturated by a photochemical reaction with at least one thiol.
