Product Summary

A thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints. This strong filler creates a smooth mixture and is ideal for general bonding and filleting. It is also extremely versatile. Often used with other fillers, it can improve the strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher, smoother surface.
