Heavy-duty cleaning with aerospace credentials
Most heavy-duty chemistry buys its strength by sacrificing substrates; most substrate-safe chemistry cannot touch real carbon. 815 QR-NF refuses the trade: heavy soils — grease, carbon, tenacious films — off steel, aluminium and titanium alike, with Pratt & Whitney PMC 1339 approval and ARP 1755B compliance behind it.
We proved it ourselves at 70 °C on diesel piston ring-groove carbon — staged ultrasonic cycles, dimensions untouched, documented in our case work. APE/NPE-free for global regulatory acceptance, it is the working chemistry for aerospace MRO and any industrial line that needs aerospace-grade substrate safety.
One operating note from its published data: its foaming tendency is high, so run it hot and degas after make-up — exactly the pattern the trial documents for your parts.
Cleaning newly manufactured parts — cutting oils, coolants, pastes rather than service-baked soils? Its general-duty sibling 815 GD is the sharper match: precision strength for manufacturing contamination, same substrate safety, same approval pedigree.
Where it earns its keep
Heavy aerospace and industrial soils — carbon and grease on steel, aluminium and titanium.
Dose: 5–30% (typ. 10%). The trial sets your exact process values; the TDS governs.
