More about this item

WEST SYSTEM 205-E Fiberglass & Repair

205 Fast Hardener is a medium-viscosity epoxy curing agent designed for the majority of marine construction and repair situations, particularly in cooler temperatures or when you need rapid cure times. This 11.31 gallon bulk container is designed for large-scale professional operations, production environments, and high-volume users who need reliable, fast-curing epoxy performance for efficient workflow.

Rapid Cure for Efficient Work:

205 Fast Hardener produces a rapid cure that develops its physical properties quickly at room temperature, allowing you to move through project stages faster. With a pot life of 9-12 minutes at 72°F, it's the preferred choice when you need to apply multiple coats in a single day, when working in cooler shop conditions, or when project timelines demand faster turnaround.

High-Performance Properties:

When mixed with 105 Epoxy Resin at the proper 5:1 ratio (five parts resin to one part hardener), the cured mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. The result is a durable epoxy system suitable for demanding structural applications and protective coatings.

Bulk Volume for Professional Operations:

The 11.31 gallon bulk container is designed for professional boatyards, production facilities, and large-scale operations where high-volume epoxy use demands economical bulk packaging. This size reduces packaging waste and provides significant cost savings for frequent users.

Key Benefits:

  • Fast Cure: Develops properties quickly for efficient workflow
  • Lower Temperature Performance: Works reliably in cooler conditions
  • High Strength: Creates rigid, structural bonds and coatings
  • Moisture Resistant: Excellent protection in marine environments
  • Medium Viscosity: Easy to mix and apply
  • Bulk Volume: 11.31 gallon for high-volume professional operations

Ideal Applications:

  • General marine construction and repair work
  • Projects requiring multiple coats in one day
  • Working in cooler shop temperatures
  • Structural bonding and laminating
  • Protective coatings and barrier coats
  • Production environments and professional boatyards

Working Characteristics:

  • Mix Ratio: 5 parts 105 Resin to 1 part 205 Hardener (by volume)
  • Pot Life at 72°F: 9-12 minutes
  • Cure to Solid State: 6-8 hours for handling and light work
  • Cure to Maximum Strength: 1-4 days for full structural performance
  • Minimum Temperature: 40°F for reliable cure

This 11.31 gallon bulk container provides exceptional value for professional operations and high-volume users who rely on the fast cure and reliable performance of 205 Hardener for efficient marine construction and repair work.
