J-B Weld
J-B Weld is a company that produces epoxy products. J-B Weld is also the name of their flagship product; a specialized, high-temperature epoxy for use in bonding metal, porcelain, wood, ceramic, and many other applications. The company is famous for its advertisements showing engine block repair with J-B Weld. While many high-temperature epoxies designed for metals are available, J-B Weld is one of the few that has been marketed to the public.
J-B Weld can withstand a constant temperature of 260 degrees C (500 degrees F), and the maximum temperature threshold is approximately 315 deg.C (600 degrees F) for 10 minutes. [1]
The company had its beginnings in the mid 1960s. Sam Bonham, at the time running a machine shop, discovered a way to create what he called a "tougher than steel" epoxy. In 1968, Sam's future wife Mary persuaded him to sell his invention and founded the J-B Weld company. Initially, they sold to automotive shops in Texas; the company currently does business in all states in the United States, and in 27 foreign countries.
Sam died suddenly in 1989. He had commented before his death, "My life's dream is for J-B WELD to be all the way around the world, and for me to see an 18-wheeler load out of here with nothing but J-B WELD."[2] Within a year of his death, Mary had opened a European hub, internationalizing the J-B Weld company and the distribution of the product.
