It is thin, highly conformable, and offers a bright reflective surface (encapsulated glass grain). 3M SOLAS tapes are U.S. Coast Guard approved and are specifically designed to enhance the visibility of life jackets, ring buoys, survival suits, and inflatable life rafts in marine environments. 3M 3150-A has an aggresive adhesive with a peel-off backing, is highly flexible, and adheres to rubber-coated cloth, vinyl-nylon laminated cloth, cured polyester cloth, PVC, and aluminum. SOLAS 6755 is the sew-on version and offers all the same reflective qualities as 3150A, but with a flexible cotton-backed fabric. SOLAS tapes are also excellent for outerwear applications such as motorcycle jackets and raingear (3150-A sticks to nylon and codura). Both 3150-A and 6755 are sold in 16-foot lengths and 55-yard rolls. Specifications and instructions for all 3M SOLAS reflective materials can be found HERE.
