In 1978, Claude Dandurand founded a company specializing in assembly solutions. His expertise at the time was mainly on mechanical fasteners and riveting tools.His association with David Van Wely a Toronto entrepreneur has awakened him to the complementarity of fasteners and adhesives. In 1989, a merger of the companies owned by Claude Dandurand and David Van Wely was at the origin of the Adfast Corporation concept. The name Adfast comes from the diminutives of the English terms (ADhesive) and (FASTener).

From these humble origins 40 years ago, Adfast serves today thousands of customers through 3 factories located in St-Laurent, and 9 sales and distribution centers in North America.
