Scott Bader Crystic\u00ae 701PA Polyester Resin for Vacuum Infusion<\/h2>\n

\n Crystic\u00ae 701PA<\/strong> is a pre-accelerated, low-viscosity isophthalic polyester resin,
\n designed for vacuum infusion and vacuum injection molding in the manufacture of composite materials.
\n It ensures effective impregnation of glass, carbon, and aramid fiber reinforcements,
\n particularly in the manufacture of large and structurally complex parts.\n <\/p>\n

\n Low viscosity ensures a steady flow of resin through the mold, while the controlled exothermic reaction
\n and a sufficiently long processing window allow for reliable work with large molds and complex geometries.\n <\/p>\n<\/section>\n

\n

Key Benefits<\/h2>\n
    \n
  • Low viscosity for effective wetting of the reinforcement and uniform resin flow.<\/li>\n
  • Intended for vacuum infusion and closed-mold processes (RTM, VARTM).<\/li>\n
  • Pre-activated system\u2014simply add the specified peroxide catalyst.<\/li>\n
  • Compatible with glass, carbon, and aramid fiber laminates.<\/li>\n
  • A controlled exothermic reaction reduces the risk of overheating in thick laminates.<\/li>\n
  • Suitable for the manufacture of large composite parts and structures.<\/li>\n
  • Curing is possible at room temperature.<\/li>\n<\/ul>\n<\/section>\n
    \n

    Recommended Use<\/h2>\n

    Crystic\u00ae 701PA is suitable for the following applications:<\/p>\n

      \n
    • vacuum infusion processes;<\/li>\n
    • vacuum infusion (RTM \/ VARTM);<\/li>\n
    • glass fiber laminates;<\/li>\n
    • carbon and aramid fiber composites;<\/li>\n
    • boat hulls and marine industry components;<\/li>\n
    • transportation and industrial panels;<\/li>\n
    • large structural or semi-structural composite parts;<\/li>\n
    • sandwich structures with proven core materials.<\/li>\n<\/ul>\n
      \n

      \n Note:<\/strong> These resins are not primarily intended for hand lamination. Thixotropic polyester resins are generally more suitable for this process.\n <\/p>\n<\/p><\/div>\n<\/section>\n

      \n The values listed are typical laboratory data. The properties of the finished laminate depend on the process,
      \n the reinforcement, and the curing conditions.\n <\/p>\n<\/section>\n

      \n

      Use<\/h2>\n
        \n
      1. Condition the resin, mold, and fittings to the working temperature.<\/li>\n
      2. Prepare the mold and apply the appropriate release agent.<\/li>\n
      3. Set up the fittings, flow materials, and vacuum system.<\/li>\n
      4. Check the vacuum seal.<\/li>\n
      5. Add 1\u20132% of the catalyst and mix thoroughly.<\/li>\n
      6. Perform the infusion in a controlled treatment window.<\/li>\n
      7. Allow it to harden completely before disassembly.<\/li>\n<\/ol>\n
        \n

        \n Important:<\/strong> A large amount of resin mixed with a hardener can significantly accelerate the reaction and cause it to overheat or even result in a boiling reaction.\n <\/p>\n<\/p><\/div>\n<\/section>\n

        \n

        Calculation of Resin Quantity<\/h2>\n

        \n The required amount of resin is calculated based on the dry weight of the reinforcement and the fiber-to-resin ratio.\n <\/p>\n

        \n Mass of dry screed = area \u00d7 g\/m\u00b2 \u00d7 number of layers \u00f7 1000\n <\/p>\n

        \n It is recommended to add a 10\u201320% process margin.\n <\/p>\n<\/section>\n
