Cost-Effective Filler for Sanding
Talc is a component in most body fillers, and is often added for fairing and smoothing the finish of fiberglass laminations. It provides a unique balance of opacity, film reinforcement, and both anti-cracking and barrier properties as part of a surface layer.
This filler is compatible with epoxy, polyester, and vinyl ester resin systems.
Mix ratio is 2:1 (filler to resin by volume).
