Adhereto® adhesion promoters are designed to create a bond between a substrate and a coating. Apply Adhereto® before applying topcoats to ensure proper adhesion of automotive paint to plastics, brass, aluminum, metal, chrome, or a variety of other surfaces. It’s designed to be used when top coating polypropylene, TPO (thermoplastic polypropylene), polypropylene/elastomer blends, other plastics, aluminum, steel, brass, and other metals, and creates a bond between a substrate and a coating, or between a dried coating and a fresh (wet) one. Adhereto is easy to use and dries in minutes, ready to spray right out of the can with no reduction required. It’s also useful for difficult sanding situations, and is clear in color
