BOSTIK Born2Bond Anaerobic Gasketing: How Liquid Gaskets Replace Pre-Formed Gaskets on Metal Flanges
How anaerobic gasketing adhesives replace pre-formed gaskets on metal flanges — that's the core question this episode answers, and Bostik's Born2Bond® Gasketing line is the answer. GA-18 and GA-10 are single-component liquid gaskets engineered to cure between mating metal surfaces, delivering 100% surface-to-surface contact that cut gaskets physically cannot achieve. Pre-formed gaskets compress unevenly, require bedding-in, and leave leak paths wherever surface irregularities exist. Born2Bond anaerobic gasketing adhesives cure in the absence of air — no bedding-in period, no compression set, no micro-movement under vibration. The result is a cohesive, stress-distributed seal across the entire flange face that resists oils, solvents, water, and cyclic fatigue loading. Target applications include engines and powertrains, pumps and compressors, gearboxes and transmissions, and liquid or gas storage assemblies. Spec the GA-18 Flexible when joint strength is the priority. Its dimethacrylate ester base delivers tensile shear strength exceeding 725 psi on steel per ISO 4587 tensile shear strength testing — the highest strength in the Born2Bond gasketing range. Viscosity runs 200,000–800,000 mPa.s, service temperature spans -67°F to 302°F (-55°C to 150°C), and maximum gap fill is 0.25 mm. Initial fixture is under 2 hours; full cure at 12 hours. Available in a 50 ml bottle for MRO use: https://www.pe-energy.com/product/bostik-born2bond-ga-18-gasketing-adhesive-50-ml-bottle/ — or scale to the 300 ml cartridge for production-line or fleet maintenance volumes: https://www.pe-energy.com/product/bostik-born2bond-ga-18-gasketing-adhesive-300-ml-cartridge/ For high-heat zones — exhaust-side flanges, high-temperature pump housings, thermal-cycling gearbox covers — spec the GA-10 High Temp anaerobic sealant. Its modified acrylate base raises the temperature ceiling to 446°F (230°C), more than doubling GA-18's upper thermal limit. Viscosity is 40,000–140,000 mPa.s, which flows more readily into tight gaps. Tensile shear strength on steel falls below the 725 psi GA-18 threshold, so confirm your joint load before substituting. Same 0.25 mm max gap fill, same fixture and cure profile. Grab the 50 ml accordion for maintenance kits: https://www.pe-energy.com/product/bostik-born2bond-ga-10-gasketing-adhesive-50-ml-accordion/ — or the 250 ml bottle for higher-volume shops: https://www.pe-energy.com/product/bostik-born2bond-ga-10-gasketing-adhesive-250-ml-bottle/ The operational case against pre-formed gaskets is direct: Born2Bond gasketing vs pre-formed gaskets means fewer SKUs in your storeroom, less flange-surface machining, lower assembly labor, and automatable single-component application on production lines. 100% surface contact eliminates the leak paths uneven gasket compression creates, outstanding fatigue strength protects joints under cyclic loading, and corrosion prevention is built into the cured film. Your RFPs and MRO blanket orders can consolidate an entire library of cut gaskets — multiple sizes and materials — down to two liquid gasket grades.
