Permabond® 2050 – Flexible cyanoacrylate instant adhesive for high-strength, impact-resistant bonds
Permabond® 2050 is a unique cyanoacrylate adhesive with a flexible formula and reinforced structure for maximum resilience under dynamic loads. Its thixotropic consistency allows for easy, drip-free application, even on vertical or irregular surfaces. Particularly noteworthy is its high peel and impact resistance, which makes it ideal for applications involving vibration, impact, or thermal expansion differences—such as when bonding different materials. Whether rubber, plastic, metal, or even difficult-to-bond materials such as silicone (in combination with Permabond POP Primer), Permabond® 2050 ensures durable, reliable bonds—even under difficult conditions.
