Vantage B&B 5151-B is a premium, ready-to-use viscous liquid compound engineered by Vantage Specialties for the targeted removal of high and low VOC polysulfide primers and sealants from metallic aircraft surfaces. Formulated to meet the precise technical requirements of United States Air Force Technical Order TO 1-1-8, this specialized chemical remover quickly penetrates, softens, and releases tough elastomeric matrices, rubberized sealants, and select polyurethane topcoats. B&B 5151-B features an advanced chemical profile that eliminates the need for harsh mechanical scraping tools that risk scratching delicate alloys. Engineered with an eco-conscious design, it contains no chlorinated solvents, phenols, heavy metals, or chromates, making it a low-odor and highly efficient alternative for critical airframe depot overhauls.

Key Features & Aviation Benefits

• Viscous Vertical Clinging: Engineered as a thick, thixotropic gel that clings securely to vertical, contoured, and underside aircraft skin joints to prolong chemical reaction times.
• Advanced Metal Substrate Safety: Rigorously evaluated to ensure zero pitting, galvanic corrosion, or hydrogen embrittlement on critical high-strength aerospace alloys.
• High Flash Point Profile: A stable operational flash point above 200°F (93°C) minimizes industrial fire hazards inside busy maintenance hangars and tight repair bays.
• Clean Environment Formula: Formulated completely free of chlorinated solvents, hazardous phenols, heavy metals, or chromium compounds to ease facility environmental disposal.
• Ready-To-Use (RTU) Configuration: Arrives fully homogenized and prepared for instant application, removing field-blending errors or consistency variances on the flight line.

Typical Applications

• Aircraft Structural Sealant Removal: Applied directly via spray, flow, brush, or mop methods over old fillet or faying surface polysulfide sealants to prep panels for fresh installations.
• Integral Fuel Tank Stripping: Highly recommended for breaking down tough, cured fuel-tank sealants during specialized interior tank inspection and structural maintenance routines.
• Depot and MRO Repair Lines: Heavily deployed across military aviation depots and commercial MRO paint shops for stripping high-adhesion elastomeric coatings and primers from landing gear pockets, door frames, and skin lap joints.
