West System Product Range

WEST SYSTEM Epoxy was created by Gougeon Brothers–sailors, builders and formulators who know the engineering and the chemistry required for high-performance composite structures. We are an employee-own, family run organization that has maintained our performance-driven development of marine epoxies since the company was founded in 1969. We continually formulate, test and improve WEST SYSTEM Resins and Hardeners and develop specialty epoxies to produce the most reliable and well-balanced epoxy systems available.

Our resin and hardener formulas, ingredients and combinations are tested to compare fatigue strength, compression strength, glass transition temperature, and peak exotherm. Qualified samples undergo additional tests for hardness, tensile strength, tensile elongation, tensile modulus, flexural strength, flexural modulus, heat deflection temperature, impact resistance and moisture exclusion effectiveness. This level of testing ensures that any change in a formula will improve one or more of a product’s characteristics without diminishing any other characteristics. Current product data is published in our instruction manuals, in Epoxyworks, and on this website.

As an ISO 9001:2015 registered company, Gougeon Brothers has numerous protocols in place to ensure the quality of every batch of epoxy we make. We are dedicated to providing the highest quality product to meet the standards our customers expect.
