- Description
- The Air Force Research Laboratory has a mandate to remove chromium - a toxic material - from its maintenance, repair and overhaul operations. Aircraft returning for planned depot maintenance may require some or all of the coating system to be removed during inspections. The aircraft subsequently must then be touched up or recoated. This involves the use of one or all of the following coating system components; a chromated chemical conversion coating as a pretreatment, a chromated primer, or a topcoat. To help meet its environmental compliance goals, the Air Force requires totally chromium-free coating (pretreatment, primer and topcoat) systems for the outer mold line surfaces of aircraft. The Air Force has tested and characterized one such coating system and is seeking additional totally chromium-free coating systems. The requirements for a commercially available, off the shelf, totally chromium-free coating system are provided below. Vendors that can supply such a system in production batches are invited to send written information and performance data to the person listed below. This information should contain, as a minimum: (i) product descriptions, including proof that no chromium compounds are present in any of the system components; (ii) Material Data Safety Sheets; (iii) supporting performance test data validated by an independent, certified laboratory, and (iv) examples of its current use on commercial and/or military aircraft. This request for information is not a solicitation for a capability statement, nor a solicitation for a proposal to procure, apply and evaluate such coatings. The Air Force may use the information received to determine if there are qualified sources and products that would warrant a subsequent full and open competition for coating system evaluation, demonstration and qualification. Any information submitted by respondents to this synopsis is strictly voluntary. The Government will not reimburse the respondents for any costs associated with their responses. The Government reserves the right to contact the submitting parties, on an as required basis, for further clarification on material provided. Original Point of Contact Dr. Elizabeth S. Berman, AFRL/MLSC 2179 12th Street, Building 652, Room 122, WPAFB, OH 45433-7717 Telephone = (937) 656-5700; Facsimile = (937) 656-4378; E-mail = elizabeth.berman@wpafb.af.mil.
