• High Strength: Delivers superior strength and durability, making it suitable for high-stress and load-bearing applications.

Technical Specifications:

• Mix Ratio: 5 parts resin to 1 part hardener by volume
• Pot Life: Varies with the choice of hardener (e.g., 10-15 minutes with 205 Fast Hardener, 20-30 minutes with 206 Slow Hardener)
• Cure Time: Varies with the choice of hardener and ambient temperature (e.g., 6-8 hours with 205 Fast Hardener, 10-15 hours with 206 Slow Hardener)
• Color: Clear, pale yellow
• Viscosity: Low (600 cP at 72°F / 22°C)

Application Instructions:

1. Surface Preparation: Ensure surfaces to be bonded are clean, dry, and free of contaminants. Sand smooth surfaces to provide a good mechanical bond.
2. Mixing: Measure 5 parts 105 Resin to 1 part hardener by volume. Mix thoroughly for at least 2 minutes, ensuring a uniform consistency.
3. Application: Apply the mixed epoxy to the prepared surfaces using a brush, roller, or squeegee. For laminating, saturate the reinforcing fabric thoroughly, removing any air bubbles.
4. Curing: Allow the epoxy to cure as per the hardener’s specifications. Avoid disturbing the assembly during this time to ensure a strong bond.
5. Finishing: Once cured, the epoxy can be sanded, painted, or varnished to achieve the desired finish.

Safety Precautions:

• Always wear protective gloves, eyewear, and clothing when handling epoxy resin and hardeners.
• 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:

• Enhanced Durability: Improves the structural integrity and longevity of marine projects, ensuring lasting performance.
• Superior Workability: Easy to use with customizable cure times, making it suitable for both amateur and professional users.
• Comprehensive System: Part of a complete epoxy system, allowing for tailored solutions to meet specific project needs, including fillers and additives for specialized applications.
