Sherwin-Williams Aerospace Coatings (Booth No. 4547), located in Andover, Kan., introduced several new products during NBAA’12. Its new urethane primer and sanding surfacer (CM0481827) can double as either a traditional sanding surfacer or as a primer. MROs and paint shops can now use one product for two purposes. And the product dries twice as fast as traditional epoxy surfacer technologies. The corrosion-inhibitive urethane primer is also chromate hazard-free and is intended for use on all aircraft.
Duncan Aviation of Lincoln, Neb. (Booth No. 5580), a provider of airframe inspections, engine maintenance, cabin and cockpit systems retrofits, painting and interior work, as well as pre-owned aircraft sales and acquisitions, has acquired several examples of a dry-ice blasting machine to accomplish a specific service bulletin for its Bombardier Challenger customers.
Redford Corp. of Kingwood, Texas (Booth No. 2235), a commercial flooring company that installs, services and maintains aircraft hangars, has been installing hangar floors for nearly three decades. Now, when a customer wants its hangar floor repaired or designed to include a distinctive floor graphic, Redford offers a solution.
US Aviation in Denton, Texas, is the first FBO in the U.S. to install stainless steel-lined fuel tanks in its fuel farm. Traditional fuel storage tanks use an epoxy inner liner, and this liner “has a tendency to break down,” according to Jeff Soules, the FBO’s senior v-p and general manager. Benefits of the stainless-steel liners include no initial startup problems or chips, flaking or biological disintegration of the epoxy, he said.
Sherwin-Williams Aerospace Coatings has introduced a full line of primers that are free of chrome and lead hazards. The products meet three key industry requirements–faster priming application, protection of the aircraft substrate and compliance with OSHA standards for chromate and lead exposure.
Sherwin-Williams has developed a flexible epoxy-based putty designed for aerospace applications such as filling rivets, seams and spot repair areas on aircraft exteriors. Drying time for the new Fill Bond putty is two to six hours, significantly faster than the typical six to eight hours for competing products, according to Sherwin-Williams.
The final two of six E-series hangars are nearly complete at developer MMU-FTC’s site at Morristown Municipal Airport, N.J. These units are both 50 feet deep by 70 feet wide. Their bifold doors are 65 feet wide and 20 feet high, able to accommodate virtually all small and midsize jets and helicopters up to the size of a Sikorsky S-76.
Manufacturers are relying more on composite materials for business aircraft construction thanks to a drop in manufacturing costs and better automation. Largely because of improved curing processes, OEMs are gradually eliminating expensive tooling and slashing the overall number of parts needed for a given aerostructure.
GMT, a Rhode Island-based composites specialist, recently delivered two highly customized showers to MAV Aircraft Services for installation in an executive Boeing 767 being done by the Fort Worth-based interiors specialist. Both composite enclosures measure 40 inches in diameter, 80 inches tall and feature curved, transparent Lexan doors and a slightly raised floor that allows water to run off around the edge and into a hidden drain.
GKN Aerospace is working toward out-of-autoclave processing of carbon-epoxy laminated structures upward of 23 feet long and 275 pounds in weight and has already manufactured components up to 8.2 feet long and weighing 175 pounds in an R&D environment.
