Abstract
Disclosed herein is an elastomeric article having a hydrogel donning coating. The hydrogel donning coating is made of a copolymer of hydroxy ethyl acrylate (HEA), hydroxy ethyl methacrylate (HEMA), and acrylic acid. The hydrogel donning coating is applied to the elastomeric article using an aqueous hydrogel dipping solution containing the hydrogel donning coating copolymer. The aqueous hydrogel dipping solution demonstrates thixotropic characteristics which allows for better manufacturing process control.
Claims17
An elastomeric article comprising:
- a substrate body having a first surface, where the substrate comprises an elastomeric material;
- and
- a hydrogel donning coating applied to at least a portion of the first surface,
- where the hydrogel donning coating comprises hydroxy ethyl acrylate (HEA), hydroxy ethyl methacrylate (HEMA) and acrylic acid (AA).
A method of coating an elastomeric article comprising:
- preparing a substrate body comprising an elastomeric material;
- immersing the substrate body in an aqueous solution of hydrogel polymer, where the aqueous solution has thixotropic properties;
- removing the article from the aqueous solution;
- and
- curing the article,
- where the hydrogel solution comprises a hydrogel polymer in an aqueous solution and where the hydrogel polymer comprises hydroxy ethyl acrylate (HEA), hydroxy ethyl methacrylate (HEMA) and acrylic acid (M) and the aqueous solution comprises a crosslinking agent, a crosslinking activator, partially crosslinked polyacrylic acid and water.
A method of coating an elastomeric article comprising:
- preparing a substrate body comprising an elastomeric material;
- immersing the substrate body in a coating solution, where the coating solution has a viscosity and a viscosity response to shear forces such that the viscosity decreases in response to increasing shear forces and the viscosity increases in response to decreasing shear forces;
- applying shear forces to the coating solution at the interface of the coating solution and the substrate body such that the viscosity of the coating solution decreases at the interface;
- removing the shear forces from the substrate body covered with coating solution such that viscosity of the coating solution increases while on the substrate body.
