Product description

West System Epoxy Fast is a transparent, low-viscosity epoxy resin that delivers excellent performance for a wide range of applications. When combined with 205 Fast Hardener, it forms a fast-curing epoxy system ideal for work at lower temperatures or projects requiring a short working time.

This epoxy system provides a strong, moisture-resistant, and durable bond, and can be used as an adhesive, filler, or laminating resin in various applications.

Benefits of West System Epoxy Fast

Short working time and fast curing.
Excellent adhesion.
Suitable in a wide range of applications.

Note: this system is not suitable as a clear finish. For that purpose, use RESION UV Epoxy (casting resin) or RESION UV Clear Coat.

Applications

Like other universal epoxy resins, West System Epoxy can be used for bonding and laminating:

Wood fibres.
Glass fibres.
Reinforcing fabrics.
Composite materials.
Various metals.

Directions for use

Ensure the surface is clean, dry, and free from grease.
Mix 5 parts 105 Epoxy Resin with 1 part 205 Fast Hardener (ratio 5:1).
Stir the mixture thoroughly for at least 3 minutes, including the sides and the bottom of the container. Only mix an amount that can be applied within the pot life.
Add fillers if required to modify the resin.
Apply the epoxy with a brush, roller, or spatula. The working time is approximately 15 minutes at 25 °C.
- For laminating: ensure complete saturation of the fabric.
- For bonding: apply a thin layer of epoxy to both surfaces to be joined.
Allow the material to cure for approximately 5–7 hours.
Sand or overcoat only once the epoxy is fully cured.

Tip: use the convenient West System pump sets to easily dispense epoxy and hardener in the correct ratio.
