WEST SYSTEM 105B Epoxy Resin Bundle with Fast Hardener & Pumps

The WEST SYSTEM 105B Epoxy Resin bundle is an essential kit for anyone looking to tackle bonding and coating projects with confidence. This convenient epoxy bundle includes one can of WEST SYSTEM 105-B Resin (126.6 fl oz) and the 205B Fast Epoxy Hardener (27.5 fl oz), along with a set of calibrated 300 Mini Pumps for precise mixing. The 205 Fast Hardener is a medium-viscosity curing agent that is effective in a majority of bonding situations, especially at lower temperatures.

One of the standout features of this epoxy system is the rapid cure time. The 205 Fast Hardener produces a quick epoxy cure that develops physical properties swiftly at room temperature, allowing you to complete your projects efficiently. With a pot life of 9 to 12 minutes at 72F (22C), you can work with the resin without feeling rushed, and it cures to a solid state in just 6 to 8 hours, reaching maximum strength within 1 to 4 days.

The 105 EPOXY RESIN itself is a clear, pale yellow, low-viscosity liquid that, when blended with the 205 Fast Hardener at a 5:1 ratio, cures into a hard, solid plastic. This epoxy is designed to wet out and bond effectively with various materials, including wood fiber, fiberglass, reinforcing fabrics, and metals. It's important to note that the 205 Fast Hardener is not intended for clear coating, making it ideal for structural applications.

Another advantage of this epoxy system is its user-friendly nature. It does not contain VOCs and has a relatively high flash point, which means it has no solvent odor, making it much friendlier to use than traditional styrenated resins. This feature is particularly beneficial for indoor projects or for users sensitive to strong odors.

Whether you are working on fiberglass boat repairs, constructing strip kayaks, or engaging in various repair projects, this epoxy is easily modified with WEST SYSTEM fillers, pigments, and additives to suit a wide range of applications. The resin viscosity is approximately 1000 centipoise at 72F (22C), ensuring that it flows well and adheres properly to surfaces.

Included in this bundle are the calibrated pumps that dispense the 105 Resin and 205 Fast Hardener at the correct mix ratio. Each pump stroke of resin corresponds to one pump stroke of hardener, yielding 0.8 fl oz of the precise 5:1 epoxy mix. These durable polypropylene pumps are designed for years of reliable service, making them a valuable addition to your toolkit.
