New Solution for Restoring Composite Aircraft Surfaces

Sherwin-Williams Aerospace Coatings has introduced Fill Bond Flex Aerospace Filler (FBF100), a new and convenient method for filling seams, rivets, and small spot repair areas on aircraft prior to painting.

The high-quality, two-component polyester filler kit is designed to block and permanently conceal surface imperfections on the exterior surfaces of composite aircraft. The lightweight filler provides strong adhesion, resistance to shrinkage, easy sanding, and outstanding stain-resistance.

Sherwin-Williams’s Fill Bond Flex Aerospace Filler kits include a mechanical dispenser package with a hardener. The solution requires no priming and cures quickly, thereby increasing shop productivity and reducing the process time inherent topcoat preparation. High Flexibility Body Filler is ideal for filling the weave structure of composite materials, as well as dents, scrapes, and scratches. The product is available in light-gray, and is compatible with Sherwin-Williams aerospace topcoats.

Sherwin-Williams Aerospace market segment manager Julie Voisin stated: “When coating an aircraft, you want to hide every surface imperfection possible for a very smooth and aesthetically-pleasing final finish. We’re making that process easier for composite aircraft with Fill Bond Flex Aerospace Filler, giving users a sag-resistant, cartridge-based application option that enhances their finishing speeds and delivers optimum results.”

For more than ninety-years, Sherwin-Williams Aerospace Coatings has provided quality, durable paint-systems and technical support to the global commercial, military, general, and business aviation sectors. The first aircraft coated by the company was Charles Lindbergh’s storied Spirit of St. Louis, the custom-built, single-engine, single-seat, high-wing monoplane in which legendary aviator made his historic, 1927 New York to Paris flight—the first nonstop, solo North Atlantic crossing made in an aircraft. 

Sherwin-Williams Aerospace Coating products include: chromated and vinyl wash pre-treatments; reducers; surfacers; primers; high performance polyester urethane and acrylic urethane clearcoats; topcoats in both single-stage and basecoat-clearcoat options; solvents and basecoat cleaners; and photoluminescent paints for aircraft propeller- and rotor-blades.
