The advent of instant adhesive dates back to 1949, when Goodrich Co. of the US discovered alpha-cyanoacrylate synthesis method. Since 1959, when the world’s first instant adhesive “Eastman 910” appeared in the market, practical applications are going on around the world and improvements on cyanoacrylate adhesive are under way night and day seeking for higher functionality. Instant adhesive means an adhesive which can stick adherends in seconds, as understood by the name.
It has passed 38 years since instant adhesives were first introduced to the global market in 1957. Today, instant adhesives are used in a variety of applications for industrial, medical, and general domestic purpose. The main reason that usage fields of instant adhesives have expanded can be found on its ease of use, which is one-part adhesive and bonds any materials strongly and instantaneously at room temperature.
Instant adhesives (cyanoacrylate adhesives ) are one-part solvent-free adhesives that cure immediately at room temperature and offer strong bonding strength. Instant adhesive was first developed in 1949 by Alan E. Ardis at Goodrich Company in the U.S., and was later developed into a product by F. B. Joyner and G. F. Hawkins at Eastman Company and marketed as Eastman 910 in 1959. Since then, various adhesive manufacturers around the world have improved and modified methods of synthesizing the main components, monomer.
Instant Adhesives (cyanoacrylate-based) sets instantly at room temperature, has powerful adhesive strength, has only one easy-to-use component, and contains no dangerous solvents. Development of the adhesive began in 1949 by Alan E. Ardis of Goodrich Corporation in the US. Then in 1959 it was introduced into the market by FB Joyner and GF Hawkins of Eastman Corporation as Eastman 910. Later improvements and modifications of the synthetic method of the major-ingredient monomer were performed by the leading adhesive manufacturers.
As already described in Three Bond Technical News 21, instant adhesives are one-part solvent-free adhesives that cure rapidly through polymerization at room temperature. These adhesives are used in a wide range of applications across various industries as a result of their strong adhesive strength. However, instant adhesives includes some disadvantages: low resistance to heat, water, and impact. Numerous patents and reports have been submitted on methods of improving these properties.
The intent of this article is to bring to light the capabilities of selectively applied PSAs to ensure you of a successful first experience.
Screen-printable pressure–sensitive adhesives (PSAs) are liquid adhesives that can be selectively applied and provide surface tack once dry. Although PSAs are used for many of the same applications as laminating adhesives (also known as transfer tapes), they don’t have to be diecut and hand positioned. You print them only where you want them.
