The Loctite® saga began in the basement laboratory of Trinity College in Hartford, Connecticut. In 1953, chemistry professor Dr. Vernon Krieble developed a cure inhibition system for a unique bonding resin that hardened in the absence of air – an anaerobic sealant. Loctite® made its official public debut at a press conference at the University Club in New York on July 26, 1956. The promise of solving the age-old problem of loose nuts and bolts in machines and appliances – a problem customers had long ago accepted as unsolvable – led to an unexpected flow of inquiries.
In the 1960s, cyanoacrylates – also known as CA or superglue, a very fast, one-part, room-temperature curing type of industrial adhesive – were added to the Loctite® brand. Silicones, epoxies, polyurethanes, acrylics and the development of further generations of Loctite® anaerobics and cyanoacrylate technology followed.
Today, Loctite® can be found almost everywhere on a common semi-trailer. “Loctite can make a truck body and trailer both more resilient and more reliable,” says Siva Ayadurai, Technical Services Manager and adds “Loctite products are engineered to meet a variety of industry challenges, including structural bonding, window glazing, seam sealing, threadlocking and thread sealing, gasketing, coating, and general assembly.”
Due to the high adhesion on metal, plastic and glass-reinforced plastic, the Loctite® brand is used in both, structural and elastic bonding. Whilst structural bonding adhesives are generally strong on tension, shear, compression and peel strength; elastic bonding adhesives provide lower adhesion but good flexibility as well as impact and environment resistance. In addition, it is utilised in the panel lamination process, providing high bond strength and cost effectiveness, and in seam sealing and thread locking as it can resist high temperatures and cure fast on an inactive surface.
“In today's competitive market, companies need the capacity and flexibility to respond quickly to new challenges,” says Treneau Joseph, National Business Development Manager. “We meet such a need with a strong commitment to research and development that has resulted in the most technically advanced range of products available today – products that speed up manufacturing processes, reduce costs, improve quality and comfortably meet national and international standards.”
