WEST SYSTEM®

From a modest boat shop that began experimenting with epoxy in the late 1960s to a trusted manufacturer and supplier of epoxies worldwide

WEST SYSTEM®

A trusted manufacturer and supplier of epoxies worldwide

Brothers Meade, Joel and Jan Gougeon founded the company in 1969 in Bay City, Michigan, driven by a shared passion for building sailboats and iceboats. Their curiosity and craftsmanship led them to pioneer the use of epoxy for marine bonding and coating, creating what would become the iconic WEST SYSTEM® brand.

From a small workshop experimenting with epoxy in the late 1960s to a globally trusted manufacturer, the Gougeon legacy now supports high-end composite builders, boatyards, repairers, woodworking and DIY communities around the world.

What began as a family of makers looking for better materials has grown into a company known for quality, ingenuity and a commitment to helping people build stronger, lighter and longer lasting projects.
