West System 4102 Microlight Filler 2 oz - Low-Density Fairing Compound

West System 4102 Microlight Filler is a premium low-density additive designed to create lightweight, easily-worked fairing compounds for marine and composite applications. This 2 oz. container provides the ideal solution for fairing large surface areas where weight savings and workability are critical.

Key Features:

• Low-density formula creates lightweight fairing compounds when mixed with epoxy resin
• Approximately 30% easier to sand than 407 Low-Density Filler or traditional microballoons
• Mixes with greater ease and handles better than comparable fillers
• More economical to use for large fairing projects
• Ideal for building up and smoothing large surface areas on hulls, decks, and composite parts

Microlight Filler is particularly well-suited for applications where you need to apply epoxy in a thicker consistency without excessive weight gain. Mix with West System epoxy resins to achieve the desired consistency for your fairing, bonding, or filling application. The improved sandability reduces finishing time and effort compared to standard microballoon fillers.
