A-A-59800, COMMERCIAL ITEM DESCRIPTION: SOLIDS ALIPHATIC POLYUREA COATING (11-SEP-2007)., This commercial item description (CID) covers a 100% solid, two component aliphatic polyurea coating intended for use on cleaned, pretreated and primed (when required) substrates which include: metals like steel, galvanized steel, aluminum, plastic, composites, wood, fabric and concrete. The polyurea coating is intended to provide an extremely tough and durable coating that is impact resistant, stone and gravel chip resistant, abrasion resistant, chemical resistant, corrosion resistant and sound and vibration damping over a wide temperature range. This aliphatic polyurea coating is UV durable and contains no hazardous diphenyl methane diisocyante (MDI) species. This material is designed for use as a UV durable spray-on protective layer for thermal insulation and abrasion resistance on vehicle interior surfaces such as doors and floors and abrasion prone vehicle exterior surfaces such as wheel wells, under carriage, foot steps, equipment storage areas and beds for tactical, combat and construction equipment. The material can be applied from a variety of application equipment ranging from high production volume plural component equipment, to moderate volume static mix cartridge guns and small volume spot repair kits. The appropriate film thickness is dependant on the particular application needs. A general guideline is to use approximately 50 mils of coating thickness in high use or chip prone areas like wheel well, undercarriage, and other similar areas and lower film thickness (approximately 20 mils) in less demanding application areas like vehicle interiors. The material can easily be repaired with small volume repair kits and readily bonds with itself.
