Introduction
Super glue is a type of fast-acting adhesive that has become an essential tool in many industries. It is used to quickly bond materials together and create strong, lasting bonds. But have you ever wondered how super glue was invented? In this article, we will explore the history, science and impact of this revolutionary adhesive.
Interview with the Inventor of Super Glue
To gain insight into the invention of super glue, we interviewed Harry Coover Jr., the inventor of the product. Coover is a renowned chemist who holds over 460 patents for various inventions. He first developed cyanoacrylate—the active ingredient in super glue—in 1942 during his work as a research chemist at Eastman Kodak Company.
When asked about the story behind his invention, Coover said: “I was investigating the possibility of using cyanoacrylates as clear plastic coatings when I discovered that they had remarkable adhesive properties. I immediately recognized the potential applications of this discovery.” Coover went on to develop the formula for super glue and applied for a patent in 1958. The patent was granted in 1960 and super glue officially hit the market.
Historical Timeline of the Invention of Super Glue
Cyanoacrylate, the main component of super glue, was first discovered in 1942. However, it wasn’t until 1951 when it was first used commercially by Loctite Corporation. The company released its first cyanoacrylate adhesive, called “Eastman #910,” for use in the aerospace industry.
The first appearance of super glue came in 1958 when Coover developed the formula for the product. He applied for a patent in the same year and it was granted two years later. In 1962, Eastman Kodak Company began marketing the product under the name “Super Glue.”
Since then, super glue technology has evolved significantly. Today, there are various types of super glues available for different applications. These include gel, foam and brush-on varieties, as well as products specifically designed for use on rubber, metal and wood.
Exploring the Science Behind Super Glue
So, what is super glue made of? It is primarily composed of cyanoacrylate, which is a type of organic compound made up of carbon, hydrogen, oxygen and nitrogen atoms. When exposed to moisture, these molecules react and form a strong bond between two surfaces.
But how does super glue actually work? According to Dr. Robert K. Prud’homme, professor of chemical engineering at Princeton University, “Cyanoacrylates polymerize rapidly upon contact with water vapor in the air, forming long chains of molecules that link the two surfaces together. This creates a strong bond that can be difficult to break.”
The Impact of Super Glue on Modern Society
Since its invention, super glue has become an indispensable tool in many industries. It is commonly used in DIY projects and industrial settings, as well as in medical applications such as wound closure and dental bonding.
In the home improvement space, super glue is a great tool for repairing broken items like ceramic mugs, toys and furniture. It can also be used to attach decorative elements to walls and other surfaces. In industrial settings, super glue is used to assemble parts, seal pipes and repair machinery.
Advancements in medical technology have also allowed for the use of super glue in various medical applications. For example, it has been used to close wounds, attach prosthetics and even reattach severed fingers.
A Look at How Different Industries Utilize Super Glue
Super glue is utilized in a variety of industries, including automotive, aerospace, electronics and more. In the automotive industry, it is often used to repair bumpers, side mirrors and other car parts. In the aerospace industry, it is used to assemble components and seal fuel tanks. And in the electronics industry, it is used to assemble circuit boards and other delicate components.
Conclusion
In conclusion, super glue was invented by Harry Coover Jr. in 1958. It is primarily composed of cyanoacrylate, which reacts with moisture to form a strong bond between two surfaces. Since its invention, super glue has become an essential tool in many industries, from DIY projects to medical applications. Different industries utilize super glue in various ways, from assembling car parts to sealing fuel tanks.
Overall, super glue has revolutionized the way we think about adhesives and continues to be an invaluable tool in our modern society.
