105 Epoxy Resin is the base material on which all WEST SYSTEM 105 System epoxy compounds are built. It is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with hardener at the proper ratio, it cures to a hard, solid plastic with superior physical properties. Based on which hardener you choose, it cures at a wide range of temperatures.  Once cured, it forms a high-strength solid that is functionally waterproof, and highly resistant to moisture vapor.
105 Epoxy Resin is designed to wet out and bond with wood fiber, fiberglass, and reinforcing fabrics. It also bonds well with a variety of metals.
Pair 105 Epoxy with corresponding letter size of 205 Fast Hardener, 206 Slow Hardener, 209 Extra Slow Hardener or 207 Special Clear Hardener.
