ABSTRACT:
A process for making powder-free medical gloves that are nevertheless easy to don involves first forming a glove on a form by successively dip-coating layers of a coagulant containing acid-soluble powder dispersed throughout, an elastomer, and an antiblocking composition with particles distributed throughout. After curing the elastomer and applying a silicone coating, the glove is removed from the form and treated successively with acid, to dissolve the powder, and with bleach, to reduce blocking. Using this process, high quality natural rubber medical gloves can be produced.
