Abstract
The present invention relates to non-stick coatings exhibiting both excellent abrasion resistance and food release, the coatings comprising a primer layer adhered to a substrate, a midcoat layer adhered to the primer layer, and a topcoat layer adhered to the midcoat layer, the primer layer containing and encapsulating large ceramic particles spaced apart from one another and extending into the midcoat layer, the midcoat layer being reinforced and being thicker than the primer layer, whereby the ceramic particles anchor the topcoat layer from being abraded away, the topcoat layer instead becoming integrated with the midcoat layer.
