Metamark M7A Crystal Etch Air Release Window Film
Create distinctive privacy and decorative glass graphics with Metamark M7A Crystal Etch. This premium etched-glass-effect vinyl combines a sparkling Crystal Etch finish with Metamark’s MetaScape® air-release adhesive technology for faster, easier installation on architectural glass.
Crystal Etch provides approximately 56% light transmission and features a distinctive glittering appearance. It offers greater visual obscuration than the other finishes in the M7A Etch Effect Series, making it an excellent option for privacy bands, decorative glass panels, conference rooms, office partitions, storefronts and computer-cut graphics.
The MetaScape® adhesive contains air-release channels that provide trapped air with an exit route from beneath the graphic. This helps reduce bubbles and simplifies the installation of larger graphics and glass-covering applications.

Application Notes
Apply to clean, smooth and properly prepared glass. Install the material unstressed, particularly around curves and recesses. Multiple panels should be installed in the same roll direction to maintain a consistent appearance. The film is not recommended for installation between two sheets of glass, over rivets, into complex recesses or on low-energy surfaces.
Important: Material sold by the linear yard is custom cut and is not returnable. Actual appearance may vary depending on lighting, glass type, viewing angle and surrounding colors. A physical sample is recommended for finish-sensitive projects.
