Material Notes:

PERMABOND® 737 is a toughened cyanoacrylate with improved impact and peel strength for maximum flexibility. Its increased temperature resistance and dark color make 737 suitable for a wide range of applications. It bonds rapidly to a variety of surfaces including aluminum, steel (both zinc-plated and uncoated), plastics and rubbers. Features & Benefits: Good gap fill (up to 0.5mm / 0.02”) Toughened and flexible Ease of use – no mixing or heat cure Black - so suitable for dark surfaces 100% reactive, no solvents Information provided by Permabond.
