Advanced Materials and Coatings Laboratory (AMCL)
Alion’s Advanced Materials and Coatings Laboratory (AMCL) specializes in the preparation and application of coatings for spacecraft and satellites.
Many years of experience, with deep technical knowledge
Application/deposition of coatings on aerospace hardware, radiators, antennas, solar arrays, and lens housing structures are done in our on-site 23’ x 18’ x 11’ climate control spray booth.
As a leading provider of commercial spacecraft thermal control products, AMCL has a 60-year history of experience in advanced thermal space coatings science and chemistry, an outstanding reputation for solving complex problems quickly, and a heritage of success for material and services.
Our engineers pioneered the development of unique materials for the protection of aerospace structures and components from Space Environmental Effects (SEE). Alion has produced materials for the Gemini and Apollo Missions, the International Space Station (ISS), NASA and DoD.
We are a developer of a “super finishing” process followed by application of military specified anti-corrosion coatings, which should increase the life of a metal part by 20%, and employ AFRL and NASA approved materials for use based on rigorous space simulation exposure. AMCL is Quality Management System ISO 9001:2015 certified.
AMCL has been working with the National Aeronautics and Space Administration (NASA) since shortly after that agency’s creation in 1958, designing and applying mission-critical thermal coatings that protect satellites and spacecraft from the harsh conditions of outer space. We have been on the cutting edge of inter-planetary missions and manned missions to the International Space Station (ISS).
Our coatings conform to NASA’s strict specifications, taking into account custom data about orbital patterns, environmental factors like temperature and radiation level, and more. The coatings help control the external temperature of space craft and limit UV radiation absorption, which allows instruments to operate more effectively .
Our other clients include: Lockheed Martin, USP, NHarris Corp., Bristol/Magellan, Aerojet, JPL, Orbital ATK, Boeing, Sandia, Litton, Northrup Gruman, ESA,Goodrich, JAXA, and Space X.
With a complete inventory of optical testing, mixing and application equipment, in state-of-the-art facilities, we can tailor thermal control coatings to fill our customers’ specific needs.
Our large-scale production facilities include three cryo-freezers; High bay area with 23’ x 18’ x 11’ climate controlled, OSHA compliant spray booth with area devoted to preparation; an inorganic spray laboratory; and an organic spray laboratory. Each lab space is devoted to specific TCMS to limit cross-contamination. Our labs are equipped with a wide variety of spray equipment including turbine sprayer with Croix spray gun, binks spray guns and airbrushes.
