  • Metal free emulsion polymers for high performance aqueous coatings
    Patent number: 5574090
    Abstract: Metal-free polymer compositions are disclosed which contain selectively swellable emulsion polymer functionalities and which are cross-linked before film formation to an extent that still allows the polymers to form a film upon application, which film is removable with a stripper solution containing swellant for the polymer functionality. When the polymers are formulated into sacrificial coatings, the polishes produce detergent resistant and removable finishes.
