Product Description
PERMABOND® 737 Cyanoacrylate is a toughened, black ethyl-based cyanoacrylate adhesive designed for maximum flexibility and improved impact and peel strength. It is 100% reactive, requires no mixing or heat cure, and is suitable for filling large gaps up to 0.5 mm. Its increased temperature resistance and dark color make it ideal for bonding dark surfaces across a wide variety of materials, including aluminum, steel, plastics, and rubbers.
Key features
- Toughened and flexible: Offers improved impact and peel strength to handle stress and provide maximum flexibility in the bonded joint.
- Fast room-temperature cure: Bonds rapidly without mixing or heat, achieving fixture handling strength on steel and rubber in seconds.
- Excellent gap filling: High-viscosity black formula efficiently fills gaps up to 0.5 mm (0.02 in) while blending seamlessly with dark surfaces.
Applications / Suitable for
- Bonding aluminum and steel, including zinc-plated and uncoated metals
- Assembling plastics and rubbers
- Applications requiring dark surface matching and moderate gap filling
