OSI didn't start in a lab. It started on a job site, which is still our favorite place to be.
It's only at a job site working shoulder-to-shoulder with the people who use our products do we fully understand the needs of residential builders, contractors and remodelers. It's there that we earn the expertise to make the world's best professional-grade caulks, sealants and adhesives — and a reputation built on quality and results. It's only at a job site do we find the insights necessary to be first-to-market with products that meet the ever-changing demands and practices of the building industry.
It was at a job site that OSI was founded in 1966 by Pat Longo, who loved nothing more than rolling up his sleeves and getting the job done. Today, members of the Longo family still work for OSI, sharing that deep commitment to the industry with a new generation.
OSI was acquired by Henkel in 2004. Today, OSI combines that tough real-world experience and deep understanding of the trades with the sophisticated global innovation and manufacturing excellence of Henkel Adhesives Technologies.
But rest assured: We still get our best ideas at a job site.
