Advanced Epoxy Resin for Superior Marine Lamination

ZDS-400AB-5 epoxy resin stands out as a cutting-edge solution for vessel lamination and repair, designed to excel in the most demanding maritime environments. Its clear appearance and optimized viscosity between 500-700 cps guarantee excellent fiber wetting and allow for perfect penetration and bonding with fiberglass, ensuring a seamless and durable finish. The cured resin achieves an impressive hardness of 85-88D, manifesting outstanding mechanical integrity over prolonged exposure to water, weather, and harsh operational conditions.

  • Low Water Absorption: With only 0.3-0.5% water uptake, ZDS-400AB-5 effectively shields hulls from moisture-induced damage, corrosion, and layer delamination.
  • Exceptional Fiber Wetting: Its sophisticated formulation creates a tight, robust laminate by maximizing resin-to-fiber contact, reaching shear strengths of 25-35 MPa.
  • Durable in Harsh Conditions: Carefully engineered for prolonged survival in aggressive marine atmospheres, it maintains structural reliability and performance in the face of saltwater, UV exposure, and mechanical stresses.
  • Easy Handling and Versatility: The ideal working time and curing profile ensure convenient application for composite lamination and vessel repairs, even for intricate structures and expansive surfaces.
