PERMABOND® 737 is a toughened cyanoacrylate with improved impact and peel strength for maximum flexibility. Its increased temperature resistance and dark colour make 737 suitable for a wide range of applications. It bonds rapidly to a variety of surfaces including aluminium, 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
