About this product
West System Additive Fillers are powdered modifiers used to thicken and adjust the working properties of West System epoxy resin systems. When blended with epoxy resin and hardener, these fillers allow the mixture to be tailored for fairing, bonding, filleting or filling applications in composite fabrication, marine construction and repair work.
Each filler type is designed for specific applications, allowing users to control the viscosity, strength, sanding properties and density of the epoxy mixture. These additives are commonly used in fibreglass laminating, boat building, mould preparation and structural bonding applications.
By combining the appropriate filler with West System 105 epoxy resin and compatible hardeners, users can create mixtures ranging from lightweight fairing compounds to stronger structural fillers depending on the project requirements.
KEY FEATURES:
- Epoxy thickening additives for West System resin systems

- Compatible with West System epoxy resin and hardeners
- Available in multiple filler types for different applications
COMMON APPLICATIONS:
- Fibreglass laminating and composite fabrication
- Boat building and marine repairs
- Fairing and surface finishing
- Filleting and gap filling
- Structural bonding and repair work
410 Microlight Filler
A low density fairing filler designed to create lightweight, easy sanding fairing compounds. Ideal for shaping and smoothing large surfaces.
411 Microsphere Blend Filler
A low density filler used for filleting, filling and coving applications with good gap filling properties and improved resistance to sagging.
413 Microfiber Filler
A structural filler designed to increase the strength of epoxy mixtures for bonding, gap filling and reinforcing joints.
417 Low Density Fairing Filler
A microballoon based filler used to create lightweight fairing putties that are easy to sand or shape after curing.
DIRECTIONS FOR USE:
After mixing epoxy resin and hardener, gradually add the selected filler while stirring until the desired consistency is achieved. The amount added will determine the viscosity and working characteristics of the epoxy mixture.
SAFETY PRECAUTIONS:
Avoid inhaling filler dust during handling. Wear appropriate protective equipment including gloves, eye protection and a dust mask when mixing powdered fillers.
