The \"B\" designator indicates a gun-grade consistency (non-sag), the \"1\/4\" denotes the 1\/4 US oz unit size, \"654\" is the PPG color\/class code, and the rapid-cure formulation (Class B) is designed to minimize aircraft ground time by delivering significantly faster tack-free and full-cure times compared to standard-cure PR-1826 grades. PR-1826 meets MIL-PRF-81733 and is approved for use in integral fuel tank sealing, faying surface sealing, and fastener sealing on commercial and military aircraft structures where resistance to aviation fuels (Jet-A, JP-4, JP-8), hydraulic fluids, and moisture is required. The Semkit packaging system keeps Part A (base) and Part B (accelerator\/curative) separated until the internal vial is broken and the contents are hand-mixed at 40 strokes at 20 strokes\/minute (or machine-mixed 1-1\/4 minutes at 20 strokes\/minute), as stated on the label; shelf life is 9 months from date of packaging when stored below 80°F. This unit is new, with a DOP of 05\/26 and expiration date of 02\/27 as visible on the label.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003ePPG Aerospace (PRC-DeSoto)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003ePR-1826 B-1\/4 654 \/ 1826B1\/4CA654SK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eSealant Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eTwo-part polysulfide, gun-grade (Class B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCure Class\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eRapid cure (Class B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003ePackaging System\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eSemkit applicator (bottle, mixing rod, accelerator vial)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eNet Contents\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e1\/4 US oz (approx. 103 mL)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eMix Ratio (by weight)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003ePer PPG spec;
