Cee-Bee PR-3500 is a premium, heavy-duty peroxide-activated polyurethane and epoxy paint stripper manufactured by McGean (Cee-Bee Aviation Products). Formulated to meet the stringent multi-specification parameters of MIL-R-81294 Type I, II, and III, AMS 1375, and Boeing D6-17487, this high-performance thixotropic liquid effectively lifts stubborn aerospace coating systems, including chemical resistant primers and topcoats. The acid-activated and peroxide-driven matrix quickly penetrates finish layers without damaging high-strength aircraft substrates or underlying metallic structures. By eliminating the need for aggressive mechanical abrasion, Cee-Bee PR-3500 ensures paint removal efficiency during depot-level maintenance while upholding critical structural safety standards.

Key Features & Aviation Benefits

• Peroxide-Activated Performance: Employs a powerful hydrogen peroxide and acid-activated system to lift multi-layer polyurethane, epoxy, and enamel coatings.
• Thixotropic Clinging Profile: Formulated as a thick, thixotropic fluid that sticks to vertical, contoured, and overhead aircraft skin panels to increase dwell time and minimize waste.
• Advanced Substrate Safety: Rigorously tested via Boeing D6-17487 parameters to ensure zero hydrogen embrittlement or structural corrosion on high-strength aircraft alloys.
• Phenol and Chromate Free: Formulated without phenols, heavy metals, or chlorinated solvents, reducing toxic emissions and simplifying waste-water handling in MRO facilities.
• Slow Evaporation Rate: Engineered with unique evaporation-inhibiting characteristics, keeping the chemical active longer for deep penetration into aged primers.

Typical Applications

• Airframe Exterior Depainting: Applied via spray or roller methods to external fuselage skin panels, wing assemblies, and tail sections for complete coating removal.
• Component Level Stripping: Used in dedicated MRO paint shops for stripping individual removed components, cowling doors, and landing gear fairings.
• Depot-Level MRO Maintenance: Employed during scheduled heavy maintenance checks (C & D checks) for commercial fleets, military aircraft, and regional airframe structures.
