The Science of Stickiness: Understanding the Different Viscosities of Super Glue
One of the crucial variables in the world of adhesives is viscosity. This term, measured in centipoise (CPS), refers to the "thickness" or "thinness" of a liquid. In the context of super glue, it can significantly impact the performance and applicability of the adhesive.
The lower the CPS, the thinner the adhesive, allowing it to flow more freely, penetrating tight spots and curing rapidly. On the other end of the spectrum, a higher CPS indicates a thicker adhesive, providing more control and longer positioning time before curing.
Let's dive into the fascinating world of varying super glue viscosities, discussing their applications and benefits.
1. Ultra Thin and Thin Super Glue (5 and 100 CPS, respectively): These glues are characterized by their quick curing times. Ultra Thin Super Glue has a curing time of 5-10 seconds, while Thin Super Glue takes 15-30 seconds to cure. Their low viscosity makes them a popular choice among woodworkers and woodturners who often use them for varnishing and other intricate tasks.
A Partent, a woodworker, attests, "I am pleased to report that the viscosity of this glue is exactly as advertised in the listing. I also like the fact that it comes in a large bottle so that I don't have to have a bunch of small tubes laying all over the shop.”
2. Medium and Thick Super Glue (700 and 1500 CPS, respectively): With curing times of 30-50 seconds for the Medium and 45-90 seconds for the Thick Super Glue, these adhesives provide more time for accurate positioning, making them suitable for detailed projects.
Marissa, who uses glue for laser wood items, shares her experience: “It holds up well and keeps my items together. Quick dry time.”
3. Super Glue Gel (10,000 CPS): As the thickest adhesive, Super Glue Gel takes up to 3 minutes to cure, providing superior control and ample time for accurate positioning.

In addition to the various types of super glue, the adhesive industry also offers tools like accelerators, fast-acting aerosol activators that speed up the bonding process for CA glues.
The different viscosities of super glue are tailored to meet specific needs and applications, which is why it's essential to choose the right one for your project. Whether you're a woodworker, wood turner, custom sign maker, furniture shop professional, or aquascaping enthusiast, understanding the implications of viscosity can help you make the most out of your super glue.
