MGS® Hardener 287 is a slow-curing agent designed for use with MGS L 285 Laminating Resin. Its extended working time makes it the optimal choice for complex and large-scale laminations, ensuring precise fiber placement and careful processing. Hardener 287 is widely used in aerospace, marine, and automotive industries for intricate layups or applications requiring a longer pot life. It is compatible with glass, carbon, and aramid fibers, providing excellent mechanical strength and dimensional stability. While it supports room-temperature curing, post-curing at 80°C enhances its thermal resistance and mechanical performance, making it suitable for high-stress applications with operational temperatures up to 100°C.

Application
  • Production of Gliders,Motor Gliders and Motor Planes
  • Boats and Shipbuilding
  • Sports Equipment
  • Model Airplanes
  • Molds and Tools
Mixing and Preparation
  • Mixing Ratio: By weight 100:40 ± 2, by volume 100:50 ± 2.
Application Techniques
Wet Layup
  • Description: Resin is applied directly to the reinforcement materials.
  • Best For: Prototyping and small-scale projects.
Vacuum Bagging
  • Description: Combines wet layup with vacuum pressure to improve laminate quality.
  • Common Uses: Aerospace, marine, and automotive industries where high strength and precision are critical.

Application Tip: Mix the resin until it is completely clear with no cloudiness. Avoid over-mixing or under-mixing, as either can compromise the curing process.

Processing Temperature
  • Recommended Processing Temperature Range:10°C to 50°C. Optimal range is 20°C to 40°C.
Curing Process
  • Initial Curing: Completed at room temperature (24 hours at 23°C).
  • Curing Agent Compatibility: Designed for exclusive use with MGS Resin 285.
  • Post-Curing:Optional heat treatment at 80°C for maximum performance.
