105 Epoxy Resin is the base material on which all WEST
SYSTEM 105 System epoxy compounds are built.
The resin is a clear pale yellow low-viscosity liquid
epoxy resin. Formulated for use with WEST SYSTEM
hardeners it can be cured in a wide temperature
range to form a high-strength solid with excellent
205 FAST HARDENER
A medium-viscosity epoxy curing agent it is used in a
majority of situations at lower temperatures and to
produce a rapid cure that develops its physical
properties quickly at room temperature.
When mixed with the 105 Resin in a five-part resin to
one-part hardener ratio the cured resin/hardener
mixture yields a rigid high-strength moisture-resistant
solid with excellent bonding and coating properties.
