- Long-Term Durability: Maintains seal integrity with UV resistance and weatherproofing capabilities
- Chemical Resistance: Polyethylene backing resists deterioration from acids, bases, and salt water exposure
- Temperature Stability: Performs reliably across extreme maritime temperature variations
- Flexible Application: Contours easily around irregular shapes and surfaces
- Low-Temperature Performance: Maintains adhesion properties even in cold weather installation
- Installation Efficiency: Significantly reduces labor time and application costs with peel-and-stick technology
Superior Construction & Composition
CROSS-LAMINATED POLYETHYLENE BACKING
Heavy-duty, acid/base-resistant, cross-laminated protective layer provides tear resistance & dimensional stability.
ADVANCED RUBBERIZED MASTIC
Specially formulated with high-tack properties to aggressively adhere to most surfaces.
EASY-PEEL RELEASE FILM
Protects the mastic until ready for use & ensures hassle-free application with precise placement control.
Factory-controlled, uniform thickness guarantees MARMAC® Marine Tape keeps a consistent 1.75 mm performance across the entire application. The unique combination of rubberized mastic and high-density cross-laminated polyethylene creates a powerful moisture barrier that prevents water ingress while maintaining flexibility in variable temperature conditions.
