Mfg # 205-B
Model # 318378
Elevate your boat building and repair projects with WEST SYSTEM #205-B Fast Hardener. Designed to work seamlessly with #105 Epoxy Resin, this hardener gives you the control you need over cure times, ensuring that your epoxy applications are perfectly timed for optimal results.
Why Choose WEST SYSTEM #205-B Fast Hardener?
Speed and Efficiency: When mixed with #105 Epoxy Resin at a 5:1 ratio, #205-B Fast Hardener offers a pot life of 9-12 minutes at 72°F and a solid cure in just 6-8 hours. It’s ideal for when you need a quick turnaround without compromising on strength. This hardener works well at temperatures as low as 40°F, making it versatile for various working conditions.
Customizable Cure Times: Depending on your project’s needs, you can also choose from #206 Slow Hardener and #209 Extra Slow Hardener. #206 Slow provides a 20-25 minute pot life and a cure time of 12-18 hours at 72°F, while #209 Extra Slow offers a 20-25 minute pot life with a cure time of 10-15 hours. Both are perfect for applications requiring a longer working time or higher temperatures.
Versatile Applications: These hardeners are perfect for a range of marine applications. Use them to wet out porous surfaces before bonding with thickened epoxy, laminate materials, or apply fabrics. They are also excellent for barrier coating, providing a durable moisture barrier with multiple coats of epoxy.
Clear Finishes: For projects requiring a clear, natural finish, #209 Extra Slow Hardener and #207 Special Clear Hardener are the go-to choices. They work well for clear fabric applications and coating wooden surfaces to create a transparent moisture barrier.
Perfect Proportions: Ensure accurate mixing with our recommended metering pumps. For group sizes "A", "B", and "C", use the 300 Mini-Pump Kit for precise 5:1 ratios. For larger sizes, the 306-23 Special Purpose Resin/Hardener pump (Model 128845) or 306-25 Special Purpose Resin/Hardener pump (Model 335703) are ideal for 3:1 or 5:1 ratios.
