Durable and Highly Adhesive with Low Shrinkage
Polyester Fairing Compound is a fibrous filler for structural repairs, bonding, and part fabrication. This structural putty is great for rebuilding broken, void, or damaged areas in composites and other materials. Unlike other body fillers, #4100 Polyester Fairing Compound exhibits low shrinkage, high impact strength, and excellent temperature and chemical resistance. It is easy to mix, has very good adhesive qualities, low moisture absorption, and can be applied in varying degrees of thickness. Use this versatile Polyester Fairing Compound to permanently repair damage on a boat or to smooth and shape the external surface of a part.
Using this fairing compound is simple. After prepping the surface, mix #4100 with a BPO Hardener. Our kits ship with white BPO hardener, however you may want to purchase either Red or Black as an off-color mix indicator. When mixing is finished, the fiber-filled putty can be applied and smoothed with a squeegee or spreader. If your application requires a perfectly smooth cosmetic surface, after using #4100 Polyester Fairing Compound, we recommend using our #4116 Lightweight Polyester Cosmetic Filler.
To get the best mechanical bond, it is recommended to use #4100 Polyester Fairing Compound on rough or fibrous surfaces. Bonding applications include: composite repair, marine fabrication, FRP composites to FRP, metal inserts to fiberglass, metal to concrete, detail blocks to FRP, wood to wood bonding, and metal to metal bonding.
