Instant Adhesives for High Speed Production Lines

Production Line Adhesives Need Precise Cure Times I recently had a call from a gentleman trying to write a process for high speed production line.   They had tested one of our cyanoacrylates (instant adhesives) and found it extremely fast. The adhesive developed strength so rapidly they planned to implement an inline packaging operation within seconds of bonding.  The...

Instant Adhesive: Cyanoacrylate Bonding & Bond Accelerators

Consistently Curing Cyanoacrylate Adhesives Cyanoacrylates (also called CA, instant adhesive or super glue) are very reactive and require stabilizers to remain liquid.  They cure when the minute amount of moisture on the surface of the parts being bonded deactivate the stabilizers and allow the material to polymerize. More Cyanoacrylates Doesn’t Equal Stronger Bondi...

Storage and Shelf life of Cyanoacrylate Adhesives

For maximum shelf life of Permabond cyanoacrylate adhesives, store unopened cyanoacrylate at 2°C (35°F) to 7°C (45°F).  Unopened cyanoacrylate products should be brought to ambient temperature before the package is opened. Once opened, the package should be left at ambient temperature. Storage below 2°C (36°F) or greater than 8°C (46°F) can adversely affect prod...

Permabond 940 Very Low Odor Cyanoacrylate Toughens 3D Prototypes

Rapid prototyping engineers are breathing a sigh of relief with Permabond’s 940-series low odor cyanoacrylate adhesives.  Permabond 940 is the choice product for use as an infiltrant for toughening prototypes made with 3D printing.  After any remaining loose powder is removed from the model, the model is dipped into an open bath of Permabond 940.  The 940 wicks into ...

NON-FLAMMABLE CYANOACRYLATE ACCELERATOR

  Traditional accelerators contain flammable solvents; Permabond® CSA-NF is non-flammable and eliminates shipping and safety concerns related to flammable solvents. Cyanoacrylate adhesives are single component adhesives that cure by reacting to small traces of moisture on the surface of the substrates being bonded.  Accelerators are used to speed the cure on ...

Permabond 820 Temp. Resistant Instant Adhesive for Component Tacking

Permabond 820 quick setting instant adhesive resists temperature ranges up to 200ºC (390ºF).  Typical ethyl cyanoacrylates only resist temperatures to 82ºC (180ºF).  Permabond 820 is a modified ethyl cyanoacrylate that has a fast fixture time and high temperature resistance making it an ideal choice when bonding components in position on dual sided PCBs prior to wav...

Industrial vs Retail Ethyl Cyanoacrylate

What is the difference between industrial cyanoacrylates and the instant adhesives I find in a retail store? Why don't high-speed production lines tend to use "no-name" retail cyanoacrylates and save money? The short answer is purity and variety. High purity, quality industrial cyanoacrylate is needed to produce consistent cure speed and bond strength – this is essenti...

How to increase the usable life of your Super Glue

How many times have you gone to fix something, delved into the depths of your tool shed, located your superglue and then discovered it has gone solid in the tube or bottle? More often than not probably! There are a lot of different “species” of this type of glue, which is technically called a cyanoacrylate adhesive. These very fast acting glues are sometimes a bit ...
