When strength and durability matter, FGCI 2435 Vinylester Putty delivers dependable performance for demanding fiberglass bonding and structural repair applications. Formulated with a Bisphenol A-based vinylester resin, this versatile putty creates strong bonds in fiberglass laminates, making it an excellent choice for marine projects where water and chemical resistance is essential.

Once catalyzed with the recommended MEKP, FGCI 2435 cures to a tack-free, sandable surface, helping you achieve a smooth, professional finish with less hassle. Its low air-inhibition properties support a clean cure, while internal laboratory testing has demonstrated fiber-level substrate failure in bonded fiberglass assemblies—highlighting its impressive bonding potential. Whether you're bonding bulkheads, stringers, or cap-to-hull assemblies, FGCI 2435 Vinylester Putty is a reliable solution for demanding structural applications.
