In 1964, my visionary father, Clyde “Bud” Boyle, founded General Sealants® in a two car garage in Whittier, CA. He identified a glaring need and developed a new standard in extruded sealants that quickly became a mainstay in the industry, manufacturing moldable, sticky solids into pre-formed tapes and beads in a variety of sizes. My father’s dedication to innovation and quality, coupled with his commitment to customer service, struck a chord and his new company established a firm footing in the marketplace. He didn’t last long in that garage, ultimately moving to our current headquarters in City of Industry, CA.

At the outset, our products were widely used in pipeline and construction applications, but the boom in aerospace and composite industries found my father and I innovating again, finding ourselves at the forefront of those burgeoning sectors. With the help of our technicians, we developed extruded sealants that cured at specific temperatures and could be stripped clean from the tooling dies. Over the years, General Sealants® grew from its humble beginnings into a worldwide leader in the pipeline, construction, aerospace/composite, telecommunication, automotive, and HVAC industries.

We consistently push the limits of sealant and adhesive technology, designing new techniques in order to meet the world’s increasingly challenging requirements. General Sealants® operates with a cutting-edge, research-focused approach and a global outlook. At the same time, quality is our number-one priority, ensuring our customers receive reliably consistent formulas of the highest standard. Since the beginning, we have made it our mission to find solutions to our customer’s application needs, while still providing the high level of customer service established as the foundation of my father’s business.

Innovation is a prime component of our DNA and we consistently drive the industry, pushing the limits of sealant and adhesive technologies. We continue to be a family-run business with the same values and commitment established by my father in that garage over fifty years ago. General Sealants® is now one of the largest privately owned sealant and adhesive companies in the world and our shared dedication and vision keeps us at the cutting edge. We’re not just a vendor; we are partners in your success. We’re family.
