WEST SYSTEM Epoxy is a versatile, high-quality, two-part epoxy that is easily modified for a wide range of coating and adhesive applications. It is used for construction and repairs requiring superior moisture resistance and high strength, therefore it is especially suited for marine applications.

All epoxies are not created equal. Epoxy products and brands can vary widely in their formulations, quality of raw materials, and their suitability for marine environments. It’s easy to market off-the-shelf industrial epoxy products as marine epoxy or formulate an epoxy with one or two favourable characteristics while sacrificing other important qualities. It’s much more difficult to balance all of the physical and mechanical properties necessary for a versatile, high-quality marine epoxy. Defining an epoxy’s performance criteria and formulating it to meet those requirements calls for good chemistry, rigorous test programs, skilful shop work, and direct experience with today’s high-performance boats and other composite structures.
