Abstract
A bathing vessel that includes a multi-layer structure of a first polymer layer and a second, adjacent polymer layer. Prior to formation of the second polymer layer on the first polymer layer, a surface of the first polymer layer is abraded and a surface wetting property of the surface is modified to promote bonding between the layers.
Claims18
A method of forming a bathing vessel comprising a multi-layer structure of a first polymer layer and a second, adjacent polymer layer, the method comprising:
- prior to formation of the second polymer layer on the first polymer layer, modifying a surface wetting property of a surface of the first polymer layer and, in unison with the modifying, abrading the surface of the first polymer layer, to promote bonding between the surface and the second polymer layer.
A method of forming a bathing vessel comprising a multi-layer structure of a layer of acrylonitrile butadiene styrene (ABS) material and an adjacent layer of polyurethane material, the method comprising:
- prior to formation of the layer of polyurethane material on the layer of ABS material, abrading a surface of the layer of ABS material with an abrasive appliance and a polar solvent.
A bathing vessel comprising:
- a base;
- and
- at least one wall extending vertically from the base, the wall comprising a multi-layer structure of a first polymer layer bonded to an adjacent second polymer layer, the first polymer layer defining a first side and an opposite, second side, the second side being bonded to the second polymer layer, wherein the second side comprises degraded polymer material of the first polymer layer, and the first side has a first surface roughness and the second side has a second surface roughness that is greater than the first surface roughness.
The bathing vessel as recited in claim 18, wherein the layer of polyurethane material is a first layer of polyurethane material, and the multi-layer structure includes a layer of acrylic material on the first layer of polyurethane material, the layer of ABS material between the layer of acrylic material and the first layer of polyurethane material, and a second layer of polyurethane material between the layer of ABS material and the first layer of polyurethane material.
