West System fillers help expand epoxy’s versatility by altering its consistency for specific applications. Each filler possesses a unique set of physical characteristics, but they can be generally categorised as either Adhesive (high density) or Fairing (low density).

Adhesive filler mixtures cure to a strong, hard-to-sand plastic suitable for structural applications like bonding, filleting and hardware bonding. Fairing filler mixtures cure to a light, easily sandable material that is generally used for cosmetic or surface applications like shaping, filling and fairing.

413 Microfibre Blend

413 Microfibre Blend is a high density filler used to create a multi-purpose, high strength adhesive used for structural applications like bonding, filleting and hardware bonding, while retaining excellent wetting and penetrating capabilities. As a blended filler, 413 Microfibre Blend, offers an added degree of thixotrophy and substantially improved spreading and working properties.

411 Microsphere Blend

411 Microsphere Blend is a low density filler which cures to a lightweight filling putty with excellent filleting characteristics. 411 Microsphere Blend is also used as a low density adhesive for edge gluing in strip plank construction.

410 Microlight

410 Microlight is the ideal low-density filler for creating a light, easily-worked fairing compound especially suited for cosmetic or surface applications like shaping, filling or fairing. 410 Microlight mixes to a very smooth creamy texture that can be trowelled to a feather edge, and is less porous than other filling compounds.
