An elastomeric glove (20) having an outer layer (21) that contains a silicone emulsion is provided. For example, in one embodiment, the glove contains a natural rubber latex substrate body (24), a donning layer (30) that is capable of being chlorinated, and an outer layer (36) formed from a silicone emulsion. It has been unexpectedly discovered that the application of a silicone emulsion to the outer layer can offset the slipperiness normally caused by chlorination and thus enhance the gripping properties of the resulting elastomeric glove. Specifically, it is believed that the silicone emulsion can inhibit the ability of halogen atoms to bond with the elastomeric material of the substrate, thereby limiting the level of slipperiness usually imparted during chlorination.
L'invention concerne un gant élastomère (20) comprenant une couche extérieure (21) qui contient une émulsion de silicone. Dans un mode de réalisation, le gant contient, par exemple, un corps de substrat (24) en latex d'élastomère-caoutchouc naturel, une couche d'enfilage (30) pouvant être chlorée et une couche extérieure (36) formée sur l'émulsion de silicone. On a découvert étonnamment que l'application de l'émulsion de silicone sur la couche extérieure permet de compenser la glissance normalement due à la chloration, et donc améliorer les propriétés de préhension du gant élastomère résultant. De manière plus spécifique, on pense que l'émulsion de silicone peut inhiber la capacité des atomes halogènes à se lier avec le matériau élastomère du substrat, ce qui limite le niveau de glissance habituellement conféré pendant chloration.
