Rust-Oleum Corporation has launched Zinsser Bondz Maximum Adhesion Primer, specifically formulated to bond any topcoat to difficult to paint surfaces. The fast drying urethane modified acrylic formula provides adhesion to hard, dense interior and exterior surfaces such as fiberglass, tile, glazed brick, aluminum, laminate and galvanized steel. It creates a permanent bond with any topcoat including two-part epoxies and solvent-based paints. Bondz has exceptional flow and leveling and superior sag resistance, according to the company, and it exhibited eight times better resistance to wet adhesion loss than XIM UMA Bonder in ASTM D2486 and D6900 in independent lab tests, so it’s ideal for use in damp or humid exterior conditions, where ordinary primers can soften and lose adhesion. Bondz has a fast-drying formula that dries to the touch in 30 minutes and can be lightly sanded and topcoated in as little as two hours, saving time and money.
