3M™ Solar Mirror Film 1100

Description3M Solar Mirror Film 1100 is a silver metallized weatherable acrylic film. It has a solar-weighted total hemispherical reflectance of 94% at air mass 1.5 and is designed for use in concentrating solar collectors. A pressure-sensitive adhesive allows application to recommended smooth substrates.

3M™ Solar Mirror Film 1100 offers a number of significant advantages over traditional glass mirrors, including higher reflectance, less weight and improved mechanical properties. These features can increase the output and design flexibility of your CSP system.

Features• Highly reflective

• Design flexibility

• Lead-free*

• Lightweight materials enable lower cost sub-structure designs
