All epoxies are not created equal. Epoxy brands can vary widely in their formulations, quality of raw materials, and their suitability for marine environments. It’s easy to market an off-the-shelf industrial epoxy product as a marine epoxy, or formulate an epoxy with one or two favorable characteristics while sacrificing other important characteristics. 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 designing a formula to meet those criteria requires good chemistry, rigorous test programs, skillful shop work, and direct experience with today’s high-performance boats and composite structures.
