Information

West System 205 Fast Hardener is a versatile, high-quality epoxy hardener designed to be mixed with West System 105 Resin to create a reliable and robust adhesive for marine and structural applications. This fast-curing hardener is ideal for projects requiring quick turnaround times, offering a balance of working time and rapid cure to meet demanding repair and construction schedules.

Key Features:

• Rapid Cure Time: 205 Fast Hardener accelerates the cure process of 105 Resin, allowing for quick handling and fast completion of projects.
• Versatile Applications: Suitable for a wide range of marine and structural applications, including bonding, laminating, fairing, and coating.
• Reliable Adhesion: Forms strong, durable bonds with a variety of materials, including wood, fiberglass, metals, and composites.
• Clear Finish: Cures to a clear, amber-colored solid that can be easily sanded, painted, or varnished.
• Consistent Performance: Provides reliable results in various environmental conditions, making it ideal for both indoor and outdoor use.

Technical Specifications:

• Mix Ratio: 5 parts 105 Resin to 1 part 205 Hardener by volume
• Pot Life: 9-12 minutes at 72°F (22°C) for a 100g mixture
• Cure Time: Initial cure to a solid state in 6-8 hours; full cure in 1-4 days, depending on temperature and humidity
• Color: Clear, amber
• Viscosity: Low to moderate (200-300 cP mixed viscosity at 72°F / 22°C)
• Minimum Application Temperature: 40°F (4°C)

Application Instructions:

1. Surface Preparation: Ensure all surfaces to be bonded are clean, dry, and free of contaminants. Sand smooth surfaces to improve mechanical adhesion.
2. Mixing: Combine 5 parts 105 Resin with 1 part 205 Hardener by volume. Mix thoroughly for at least 2 minutes until the blend is uniform and free of streaks.
3. Application: Apply the mixed epoxy to the prepared surfaces using a brush, roller, or spreader. Work quickly due to the shorter pot life of the fast hardener.
4. Clamping: Secure the parts in position with clamps or weights. Avoid excessive clamping pressure that could squeeze out the adhesive.
5. Curing: Allow the epoxy to cure undisturbed. Initial set occurs in 6-8 hours at 72°F (22°C). Full cure is achieved within 1-4 days.

Safety Precautions:

• Always wear protective gloves, eyewear, and clothing when handling epoxy hardeners and resins.
• Work in a well-ventilated area to avoid inhaling fumes.
• Avoid contact with skin and eyes. In case of contact, wash thoroughly with soap and water and seek medical attention if necessary.
• Store in a cool, dry place away from direct sunlight and moisture.

Benefits:

• Quick Turnaround: Accelerates project timelines by reducing cure times, allowing for faster handling and subsequent steps.
• Enhanced Strength: Delivers high-strength, durable bonds that enhance the structural integrity of repairs and constructions.
• User-Friendly: Easy to mix and apply, providing consistent results for both professional and amateur users.
• Part of a Complete System: Compatible with West System 105 Resin and a variety of fillers and additives, offering tailored solutions for specific project needs.

West System 205 Fast Hardener is the perfect choice for those seeking efficiency and reliability in their marine and structural projects. Its rapid curing properties and strong adhesion make it an essential component for high-quality, durable results.
