Fillers

403 Microfibers is used as a thickening additive with resin/hardener to create a multi-purpose adhesive, especially for bonding wood.

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.

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 West System’s most versatile epoxy filler.

407 Low-Density filler is a blended micro-balloon-based filler added to epoxy resin/hardener to make fairing putties that are easy to sand or carve.

410 Microlight™ is the ideal low-density filler for creating a light, easily-worked epoxy fairing compound especially suited for fairing large areas.
