A balance of physical and mechanical properties is necessary for a versatile, high-quality epoxy. We've defined this performance criteria by designing a formula through good chemistry, rigorous testing, skilful shop work, and direct experience.

WEST SYSTEM's two-part (resin and hardener) epoxy systems are developed for long-lasting repairs to high-performance composites. Allowing the user to tailor the epoxy to their exact needs without losing performance is what WEST SYSTEM has always been about.
