WEST System Fillers
WEST SYSTEM Epoxy fillers are used to thicken the basic epoxy resin/hardener mixture for specific applications. Each epoxy filler possesses a unique set of physical characteristics, but they can generally be categorized as either Adhesive (high-density) for bonding applications or Fairing (low-density) for sanding and fairing applications. Adding these filling agents to blended epoxy resin and hardener allows you to control the consistency of the epoxy, bridge gaps in joints, create either strong or sandable fillets with epoxy, or alter the cured density of epoxy making it easier to sand smooth.

WEST System 403 Microfibers Adhesive Filler, is a fine fiber blend. Use it to thicken epoxy blended resin/hardener and create a multi-purpose adhesive. It’s most popular use is for bonding wood. Epoxy thickened with microfibers has good gap-filling qualities but will still do an excellent job of wetting-out/penetrating into wood fibers. You can blend it into any WEST SYSTEM 105 Resin/20X Hardener combination, G/flex Epoxy 650, or G/5 Five-Minute Adhesive. Blended with epoxy, it will cure to an off-white color.

WEST System 406 Colloidal Silica is an epoxy thickening additive used to control the viscosity of the epoxy. It prevents epoxy runoff in vertical and overhead joints. This is a very strong filler. It creates a smooth mixture, ideal for general epoxy bonding and filleting. It is also our most versatile epoxy filler. Often used in combination with other fillers, 406 can be used to improve strength, abrasion resistance, and consistency of epoxy fairing compounds. The result is a tougher, smoother surface.

WEST System 407 Low-Density is a blended microballoon-based fairing filler for WEST System Epoxy. Add 407 to a mixture of epoxy resin/hardener to create a fairing putty. It’s easy to sand or carve this putty once it has cured. Low-Density Fairing Filler filler is reasonably strong on a strength-to-weight basis.

WEST System 410-2 Microlight, 2 oz

WEST System 410 Microlight is the ideal low-density filler. When you blend it with epoxy, it creates a light, easily-worked epoxy fairing compound. It’s especially suited for fairing large areas. We formulated Microlight to mix into epoxy more easily than typical fairing fillers.

After epoxy thickened with 410 cures, it is about 30% easier to sand than most other epoxy-based fairing compounds. Epoxy thickened with Microlight feathers to a fine edge. It’s more economical for large fairing jobs.

We don’t recommend using 410 under dark paint, or other surfaces subject to high temperatures.
