Abstract

The present invention provides a homogeneous, sprayable liquid composition formulated for spraying onto a substrate to protectively cover at least a portion of a surface of the substrate, the sprayable liquid composition comprising: (a) an aqueous polyurethane dispersion (PUD); (b) a pigment; (c) a surfactant; and (d) a silica compound, the sprayable liquid composition, once dry, forming a solid, uniform, peelable coating adhered to the substrate without use of a separate adhesive coating layer, the peelable coating having a greater scratch resistance, and the peelable coating having a greater fuel staining resistance compared to peelable, specialty rubber coatings. The peelable coating may also find use in or as automotive OEM delivery wraps, transportation coatings, ride-hailing advertisements; agricultural and mining equipment; in architectural coatings such as floor coatings, bath tub and shower protective peelable coatings; and in home and office furniture protective coverings.
