ABSTRACT:
A polymer composition in the form of an alloy is disclosed, having hydrophilic and anti-fogging properties. The polymer alloy can be used as a coating, as an unsupported film or as a substrate having the desired anti-fogging properties.
The composition can be used where hydrophilic properties are desired. Surfaces coated with the composition described herein are more readily wetted by water or aqueous fluids, and may have a coefficient of friction of 0.10 or less when in contact with water.
The preferred composition contains a water-soluble polyvinyl alcohol and a water-soluble polyvinyl pyrollidone polymer in a weight ratio of about 4:1 to about 1:10.
A crosslinking agent comprised of a melamine, a mineral acid or a strong organic acid is included.
The composition is preferably applied to a substrate, such as a lens, and cured to form the coating.
