Definitions

  • the present invention relates to an intermediate primer coat which enhances the adhesion of a coating polymer on to elastomeric rubber articles.
  • the concept of using coatings for flexible rubber articles has been utilised almost since the first rubber articles were produced over the last century.
  • the early coating materials used for rubber articles comprised of applied powders, such as talc, calcium carbonate, various types of cornstarch or other mineral powders, as a means of lubricating the rubber surface, especially on the interior donning surface of articles such as gloves, in order to facilitate easy donning. These powders have undesirable side effects, in particular for hygiene and medical reasons, in the case of medical gloves and other medical items.
  • the current popular process is to coat the surfaces of gloves with polymers which have low friction between the surface of the rubber and the wearers hands and also low friction between adjacent surfaces, so as the avoid the sticking of internal or external surfaces of the gloves, which would otherwise impair the donning and dispensing of rubber gloves.
  • the most commonly applied polymers are acrylic polymers and polyurethane polymers, or mixtures of the two, but any other polymeric material can be utilised.
  • the polymer to be applied to glove surfaces may be in the form of an aqueous dispersion or solution or a non-aqueous dispersion or solution, as long as it is applied in a liquid carrier.
  • the polymer or polymer mixtures, in a liquid form, after being applied to the rubber surface is dried to remove or partially remove the liquid carrier, which leaves dry or partially dry polymer on the rubber surface, as a coating and the polymer may be present as a continuous thin film or as a uniformly applied non-continuous coating, similar to that of a powder coating.
