405 FILLETING BLEND

What is West System 405 Filleting Blend and why choose it

West System 405 Filleting Blend is an adhesive filler designed to be mixed with West System epoxy resins to create strong, wood‑toned joints and fillets. It is formulated specifically for use on naturally finished wood, providing a consistent brown colour that blends into timber interiors while delivering structural strength. When added to mixed epoxy, it thickens the resin/hardener to a smooth, non-sag paste that is easy to apply and requires minimal sanding once cured.

This product is an excellent choice for boatbuilding, marine repair and fine woodworking where you need both high-strength bonding and an attractive, woodlike appearance in the finished joint.

Main features

• Adhesive filler for epoxy: Developed to thicken West System epoxy mixtures for bonding and filleting applications.
• Wood‑toned appearance: Medium brown colour that cures to a darker brown, ideal for visible joints on natural wood finishes.
• Strong structural bonds: Classified as a high‑density adhesive filler, suitable for structural bonding, fillet bonding and braces.
• Smooth, easily tooled fillets: Produces fillets that are easy to shape and that require only light sanding after curing.
• Customisable shade: Can be blended with other West System fillers to adjust the final colour of the epoxy mix.
• Versatile compatibility: Designed for use with West System 105 Resin and 200 Series Hardeners, as well as G/flex 650 and G/5 Five‑Minute Adhesive (information based on manufacturer data, not independently verified).

Applications and use cases

Marine construction and repair

• Wood fillets in hulls and interiors: Used to create smooth, radiused fillets between bulkheads, frames and hull planking where a natural wood interior finish is desired.
• Structural bonding: Suitable for bonding wooden structural elements where high strength and a visually compatible bond line are needed.

Woodworking and furniture

• Decorative yet structural joints: Ideal for furniture, cabinets and built‑ins where joints must be both strong and visually discreet.
• Gap filling in timber assemblies: The thickened epoxy mix can bridge small gaps in wooden joints while maintaining structural performance.

General epoxy filleting

• Fillet bonding: Forms continuous epoxy fillets that increase bonding area and act as structural braces between parts.
• Multi‑purpose adhesive: When mixed to the appropriate consistency, creates a high‑strength, gap‑filling adhesive for a wide variety of wood bonding tasks.
