ABSTRACT:
A method for providing improved adhesion of a waterborne, inorganic barrier coating to polyolefin substrate is described. The method involves corona-treatment of the substrate and applying a barrier coating composition.
The polyolefin substrate is coated with an acrylic primer layer and then an inorganic barrier layer of a copolysilicate of lithium and potassium is applied.
