What is CA Glue and How Does It Cure?
Posted by Klingspor's Woodworking Shop on Jun 28th 2021
The term "CA" is short for cyanoacrylate, a one-part instant cure adhesive. A chemical synthesis process produces CA by changing acetate to acrylate. This process is the first step in making CAs. Stick Fast™ CA is then further distilled until this crude acrylate becomes a CA monomer that is at least 99.5% pure. This high level of purity gives Stick Fast™ superior cure strength, reduces cure times, and helps increase stability and shelf life.
Stick Fast™ cyanoacrylates are MADE IN THE USA, providing you with the freshest materials available and are produced at the highest industrial quality standards.
A high pH level initiates the curing mechanism of CA. In most cases, the moisture found on any surface combined with the elements of the surface creates an adequate curing environment. Organic acids are used as stabilizers in the manufacturing of CAs, which is why the higher the acid level is on the bonding surface the slower the cure. These acidic stabilizers are a major facilitator in keeping the CA in its liquid form. Stick Fast™ CAs are ethyl based, surface-insensitive formulated for bonding a wide range of similar and dissimilar materials.
Stick Fast™ ACTIVATOR will accelerate the cure faster than moisture alone and may be the only way to create a cure on some highly acidic surfaces. Using too much ACTIVATOR will create an exothermic reaction that causes foaming, reducing bonding strength. Using AEROSOL ACTIVATOR allows for a lighter, more even application that minimizes this foaming tendency.
