Abstract:
A plastic article of manufacture having an antislip surface, comprising:a base member comprising a polyolefin thermoplastic polymer material, and a plurality of asperities comprising an antislip polymer that comprises a polyurea-based polymer applied and durably bonded directly onto a surface of said base member over at least a selected surface area thereof so as to form a direct intimate bond between said antislip polymer of said asperities and said polyolefin thermoplastic polymer material of said base member, wherein said asperities are separate from one another to such an extent so as to leave a portion of said surface of said base member exposed between said asperities and so as not to form a continuous film of said antislip polymer over said selected surface area of said base member, wherein at least some of said asperities have respective substantially circular shapes and at least others of said asperities have respective unique non-uniform amoeboid shapes, in a plane of said selected surface area, as formed by spraying droplets of said antislip polymer onto said surface of said base member, and wherein said asperities provide a relatively increased coefficient of friction over said selected surface area in comparison to a base coefficient of friction of said base member without said asperities.
