Description

R840I series is formulated from a high-performance halogenated vinylester resin, combined with specialized additives.

This resin is specifically designed for closed-molding processes such as vacuum infusion and Light-RTM, offering excellent fire resistance, superior mechanical performance, and enhanced chemical durability, while maintaining stable flow behavior during processing.

Product Characteristics:

  • Fire-retardant formulation based on halogenated vinylester resin
  • Superior mechanical strength compared to conventional polyester fire-retardant resins
  • Excellent chemical resistance and durability in demanding environments
  • Optimized viscosity for controlled flow during infusion
  • Good mechanical strength and laminate consolidation
  • Consistent gel time and curing behavior
  • Good bonding between layers

Primary Applications:

R840I series is recommended for composite parts requiring fire protection and high mechanical performance, such as:

  • Transportation components (rail systems, buses, specialty vehicles, etc.)
  • Infrastructure and structural composite elements
  • Composite parts exposed to fire-risk or corrosive environments

Recommended Application Methods:

  • RTM (Resin Transfer Molding)
  • Infusion / Light-RTM

Description and Specifications

The advanced technology behind Gelco’s resins gives them the following properties:

Chemical resistance

Chemical resistance measures a material’s ability to withstand the action of chemical substances without degrading

Fire resistance

Fire resistance measures a material’s ability to slow the spread of flames and limit damage in the event of a fire

Good bonding between layers

Good interlayer adhesion indicates that the different layers of a material remain firmly bonded without separating
