Permabond 2050 Clear Cyanoacrylate Instant Adhesive, 1 Pound Bottle (CA020500016Z0101)
Permabond 2050 — Clear Cyanoacrylate Instant Adhesive, 1 Pound Bottle
Permabond 2050 is a general-purpose clear cyanoacrylate (CA) instant adhesive offering fast fixture times and strong bonds on a wide range of substrates including metals, plastics, rubber, ceramics, and wood. The low-viscosity formula wicks into tight joints for excellent surface contact, making it ideal for close-fitting assemblies in electronics, industrial, and manufacturing applications.

Frequently Asked Questions
What is the difference between Permabond 2050 and other CA adhesives?
Permabond 2050 is a low-viscosity general-purpose CA. Its thin consistency allows it to wick into tight-fitting joints by capillary action. For gap-filling applications, a higher-viscosity CA such as Permabond 910 or 940 may be more appropriate.
What surfaces does Permabond 2050 bond well to?
It bonds well to metals, most plastics, rubber, ceramics, and wood. Difficult-to-bond plastics such as polyethylene, polypropylene, and PTFE require a surface primer (such as Permabond POP) for adequate adhesion.
How fast does Permabond 2050 cure?
Fixture time is typically seconds to minutes depending on substrate, humidity, and gap size. Full cure develops over 24 hours. Higher humidity accelerates cure; very low humidity or acidic surfaces may slow it.
Is Permabond 2050 suitable for use on electronics?
Yes, with caution. Cyanoacrylates emit acetic acid vapors during cure which can cause white haze (blooming) on nearby surfaces. Ensure adequate ventilation and avoid applying near sensitive optical or connector components.
How should Permabond 2050 be stored?
Store in a cool, dry location away from moisture. Refrigeration (35–50°F) extends shelf life. Always replace the cap immediately after use to prevent moisture-initiated cure in the bottle.
