403 Microfibers, a fine fiber blend, is used as a thickening additive with resin/hardener to create a multi-purpose adhesive, especially for bonding wood. Epoxy thickened with microfibers has good gap-filling qualities while retaining excellent wetting/penetrating capability.

404 High-Density Adhesive Filler is an epoxy thickening additive developed for maximum physical adhesive properties in hardware bonding where high-cyclic loads are anticipated. It can also be used for filleting and gap filling with epoxy where maximum strength is necessary.

405 Filleting Blend Adhesive Filler is a strong, wood-toned epoxy filler for use in epoxy joints and epoxy fillets on naturally finished wood. It mixes easily with epoxy and lets you create fillets that are smooth and require little sanding. Its color is a consistent brown, so 405 Filleting Blend can be blended with other WEST SYSTEM Fillers to modify the shade of thickened epoxy.

406 Colloidal Silica is an epoxy thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints. This is a very strong filler that 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, resulting in a tougher, smoother surface.

407 Low-Density filler is a blended microballoon-based filler added to epoxy resin/hardener to make fairing putties that are easy to sand or carve. This epoxy filler is reasonably strong on a strength-to-weight basis. Cures with epoxy to a dark red/brown color.

410 Microlight™ is the ideal low-density filler for creating a light, easily-worked epoxy fairing compound especially suited for fairing large areas. Microlight mixes with epoxy with greater ease than 407 Low-Density filler or microballoons and is approximately 30% easier to sand after the epoxy/410  mixture cures. Epoxy thickened with Microlight feathers to a fine edge and is also more economical for large fairing jobs. Not recommended under dark paint or other surfaces subject to high temperatures.
