Title:  Zero Volatile Organic Compound (VOC) Aircraft Coatings
Research & Technical Areas:  Materials/Processes

  Objective:  Identify and develop zero volatile organic compound (VOC) emissions aircraft coatings that will assist facilities in California and elsewhere to achieve VOC emissions compliance.
  Description:  Federal and local environmental regulations restrict the VOC content of the coatings used on aerospace hardware. High-VOC-containing solvents such as methylethylketone (MEK), toluene and xylene are commonly used as diluents in aerospace primer, topcoats, rain erosion, and specialty coatings. Restrictions on these coatings arise from regulations governing material limitations as well as VOC emission restrictions imposed on facilities via permit regulations. Currently, DoD manufacturing, operation, and rework facilities are affected by these regulations depending on specific federal, state and local regulations that apply. Of specific interest are zero-VOC formulations for polyurethane based topcoats (MIL-PRF-85285C) and expoxy-based primers (MIL-P-23377G)

  PHASE I: Demonstrate an innovative approach to eliminate VOCs in coating application processes. Elimination of VOCs can be achieved through material or process modifications and development work should demonstrate fundamental compliance with the specifications that govern the materials.
  
  PHASE II: Develop, test and demonstrate that the materials and/or technology meets the performance requirements of the baseline specification while eliminating emissions of VOCs.

  DUAL USE COMMERCIALIZATION: Military application: Potential transition of the technology via material specification allowances. Logistical concerns with the new materials and/or technology will be resolved. Commercial application: Commercial aircraft manufacturers will realize the benefits of zero-VOC coatings that may be developed under this program.

Questions and Answers:
Q: Would it be possible to use powder coatings (which are zero VOC) in the areas you are
interested in?
A: Powder coatings are of limited use and interest. Generally in the military aircraft manufacturing environment, subcomponents or the entire aircraft is painted at the end of assembly with spray application techniques.
Q: Cannot locate MIL-P-23377G, epoxy-based primer, referenced in the Description. I did an online search. Can you help?
A: If you search on "MIL-P-23377G," several manufacturers and references are identified on the Web. We cannot recommend any specific vendor.
Q: Will you consider radiation curable coatings for the primer and topcoat?
A: Yes.
