Abstract
The present invention provides a composition as well as a method for repairing deep scratches, gouges, etc. and which is particularly useful for aircraft and aerospace transparency repair. The composition is a blend of a polishable two-part, solvent-free, polyurethane coating composition for repairing the transparencies and which, after application, cures to a thermoset polyurethane. An optical grid is emplaced over the area to be repaired prior to applying the blend.
Claims12
A method for repairing an aerospace or aircraft transparency that comprises an electromagnetic shielding coating, the method comprising:
- a) removing any coating surrounding a scratched or gouged transparency area of the aerospace or aircraft transparency to be repaired;
- b) emplacing an electromagnetic shielding optical grid atop the scratched or gouged transparency area of the aerospace or aircraft transparency;
- c) applying to the scratched or gouged transparency area of the aerospace or aircraft transparency atop the electromagnetic shielding optical grid, a two-part component system which comprises a blend of:
- (1) a hydroxy-terminated polyol, a light stabilizer and a catalyst defining Part A;
- (2) an aliphatic polyisocyanate defining Part B;
- and
- d) placing a fluorinated ethylene propylene (FEP) release film thereover and smoothing the FEP release film, and, thereafter, curing the blend which when cured, provides a thermoset polyurethane.
