The West System 105-B Epoxy Resin is a versatile and essential base material for all your epoxy projects. This clear, pale yellow, low-viscosity liquid is designed to be blended with one of four hardeners, allowing it to cure into a high-strength solid that is functionally waterproof. Its unique formulation provides excellent resistance to moisture vapor, making it ideal for various applications.

One of the standout features of this epoxy is its ability to be easily modified with West System Fillers, Additives, and Pigments. This means you can tailor the epoxy to meet the specific handling characteristics required for your project. Whether you need a pigmented coating, high-strength epoxy joints, or a fairing compound, the 105 Resin can be adjusted to suit your needs.

When combined with the West System 205 Fast Hardener or 206 Slow Hardener at a 5:1 ratio, the 105 Resin cures to develop superior physical properties at room temperature. This combination ensures excellent structural bonding properties, making it suitable for a wide range of applications. It can easily coat fiberglass and other porous substrates, providing a reliable and durable finish.

For those looking for an exceptionally clear finish, the 105 Resin can be mixed with the Blush-Free 207 Extra Clear Hardener at a 3:1 ratio. This combination is perfect for coating and fiberglass cloth applications where a natural wood finish is desired. Notably, it will not blush or turn cloudy, even in humid conditions, ensuring a pristine appearance.

Additionally, when paired with the 209 Extra Slow Hardener at a 3:1 ratio, the 105 Resin is particularly effective for general coating and structural bonding in warm or humid environments. This formulation creates a clear, amber-colored solid with excellent physical properties and moisture-vapor resistance, making it a reliable choice for various projects.

In summary, the West System 105-B Epoxy Resin is an indispensable product for anyone looking to achieve high-strength bonding and a flawless finish. Its adaptability and superior performance make it a top choice for both professionals and DIY enthusiasts alike.
