Worldwide industry leader in adhesives, sealants, and coatings, Loctite manufactures more than 1,000 types of industrial, automotive, hobbyist, and home-use products for threadlocking, threadsealing, structural bonding, lubricating, gasketing, retaining, surface treating, and cleaning, in addition to semi-automatic dispensing systems and application accessories. The Loctite Corporation has been prolifically successful since 1956 and continuously innovative in its research methods, product and systems development, testing assessment, and industry-shaping advances in product design and performance.

Loctite branding encompasses a broad umbrella of problem-solving products designed to facilitate engineering and assembly, retain structural integrity of equipment, streamline mechanical operations, and reduce labor and materials costs. Now a wholly-owned subsidiary of Henkel, Loctite was originally propelled to the forefront of the liquid adhesive and sealant industry with the development of a remarkable anaerobic adhesive that, when applied to flow into crevices, proved capable of bonding, hardening, and locking together nuts, bolts, and fasteners.

High Quality Assortments From Loctite

The synthetic sealant, originally labled “anaerobic permafil,” was developed by Trinity College chemist Dr. Vernon Krieble and his son, Robert, in their Hartford, Connecticut laboratory. The Kriebles formed the American Sealants Company in 1953 and called its pilot product Loctite, which made its public debut in 1956 at a New York City press conference. Engineers and business leaders were initially skeptical, yet they were intrigued by the potential cost savings to be realized by eliminating the need for mechanical locking devices. Skepticism soon gave way to enthusiasm when industry leaders acknowledged that, despite precise engineering, machinery and motorized equipment subject to vibration, repetitive motion, friction, wear, and normal usage had always been problem sources of inner space leakage, looseness, and abrasion.

Proving to be an invaluable addition to mechanical engineering and a superior cost-efficiency tool for industrial and automotive manufacturing, Loctite products gained tremendous popularity in the 60s, and American Sealants changed its name to the Loctite Corporation as it continued to grow. The company’s development of the cyanoacrylate adhesive "Super Glue" in its laboratories in Ireland and Connecticut, and its subsequently successful marketing strategy, made "Super Glue" a consumer favorite and the most significant contribution to Loctite’s growth and expansion.

Continuing to manufacture a diverse line of high-technology products and application systems designed for various locking and sealing strengths, vicosities, temperatures, application methods, substrate materials, and cure rates, Loctite readily expanded into the international market. Merging with International Sealants Corporation in 1980 greatly increased foreign revenue and made Loctite a solid transnational corporation with a healthy reputation as an elite provider of dependable, valuable products and systems.

Acquired in January 1997 by Henkel KGaA, international chemical, detergent, cosmetics, and industrial adhesive manufacturing giant and Fortune 500 company based in Dusseldorf, Germany, Loctite continues to enjoy worldwide success and security as the industry leader in liquid and spray adhesives, coatings, sealants, lubricants, epoxies, fillers, surface treatments, and a vast assortment of other innovative products, systems, and services. Loctite’s principal subsidiaries are Loctite Canada and Loctite Mexico, and its principal divisions are Industrial Automotive, Industrial Production, Industrial Maintenance, Electronics Industry, and Medical Equipment. Research, Development and Engineering Facilities are located in the United States, Germany, Japan, and Ireland.

Under the Henkel holdings flag, The Loctite Corporation continues to supply its products to consumer and industrial markets in more than 80 countries to reduce manufacturing costs and increase processing speed, improve quality and performance, and exceed national and international standards. Recent technological advances include the development of specialty adhesives for use in the production of medical equipment. With an acute understanding of environmental issues, Loctite has been actively increasing its focus and development of green products and sustainable technologies.
