Selective Degradation and Removal of Silyl-Containing Topcoats from Non-Metallic Substrates using Environmentally Friendly Fluoride Salts

Product Number: 51323-18797-SG

$20.00

topcoats utilized on the exterior skin of Department of Defense (DoD) aircraft (i.e., fixed and rotary wing) and ground support equipment (GSE) are two-component (2K) polyurethanes (PUs) that are qualified to MIL-PRF-85285 performance requirements. These topcoats are formed from the chemical MARCH reaction of hydroxyl- and isocyanate-functional molecules to generate highly cross-linked polymeric networks that contain carbamate (i.e., urethane) linkages. Formation of these cross-linked networks result in durable coatings with excellent hydrocarbon resistance, mechanical and thermal properties, including resistance to ultraviolet (UV) degradation from sunlight.
