West System Epoxy A Packs Information

The West System A Pack Epoxy kit combines the West System 105 epoxy resin and either the 205 (fast) or 206 (slow) hardener.

Which West System Hardener should I use, the 205 (fast) or 206 (slow) hardener?

West Systems produce two basic hardeners, the 205 (fast) and the 206 (slow), each with different attributes.

  • West System 205 (fast) hardener:- A medium viscosity curing agent, useful in lower temperatures and to produce a rapid cure that develops the epoxies physical properties quickly at room temperature. Suitable for temperatures approximately ranging between 5°C to 30°C.
  • West System 206 (slow) hardener:- A low-viscosity curing agent, useful when extended working and cure time is required or to provide adequate working time at higher temperatures. Suitable for temperatures approximately ranging between 14°C to 33°C.

When either hardener is mixed with the West System 105 resin in a five part resin to one part hardener ratio, the cured epoxy mixture yields a rigid, high-strength, moisture resistant, solid finish with excellent bonding and coating properties.
