Brief: Discover the durability and versatility of Unsaturated Polyester Resin (UPR) in marine and industrial applications. This corrosion-resistant marine-grade FRP composite offers high strength-to-weight ratio, thermal stability, and fast curing, making it ideal for boat hulls, offshore platforms, and more.
Related Product Features:
  • High strength-to-weight ratio for lightweight structural applications.
  • Thermal stability withstands temperatures up to 135°C.
  • Customizable for flame retardancy, UV resistance, or low shrinkage.
  • Fast curing with ambient or elevated temperature options for rapid production.
  • Excellent chemical resistance for harsh environments.
  • Versatile use in marine, automotive, construction, and electrical industries.
  • Certified to ISO 9001, REACH, and RoHS standards.
  • Available in light yellow viscous liquid with precise viscosity and density specifications.
FAQ:
  • What are the key applications of Unsaturated Polyester Resin (UPR)?
    UPR is widely used in marine industry for boat hulls and decks, automotive for body panels, construction for sanitary wares, electrical for circuit boards, and energy for desalination plants and solar panels.
  • How does the curing process work for UPR?
    The curing process involves gelation where initiators generate free radicals to cross-link polymer chains, followed by post-curing at 80-120°C to enhance mechanical strength. Curing can be done at ambient or elevated temperatures.
  • What safety precautions should be taken when handling UPR?
    Work in ventilated areas to avoid inhaling styrene vapors, wear PPE like gloves and goggles, and use calibrated scales for catalyst ratios. Store in HDPE drums at 15-25°C and avoid freezing or direct sunlight.
