H.B.Fuller TONSAN 1272

Key Advantages

1. Ultra-high permanent locking strength & superior heat resistance:
Top-tier clamping force against severe vibration & impact for heavy-duty thermal equipment; disassembly requires heating above 180℃; continuous service temperature ranges from -60℃ to 230℃, no softening or creep failure under long-term high temperature.
2. High thixotropic anti-sagging formula: No flowing down on inclined/overhead threads, ideal for narrow high-temperature cavities around engine exhaust and boilers.
3. 3-in-1 thread protection: Anti-vibration loosening, fluid sealing and rust prevention, completely replaces traditional mechanical anti-loosening washers to avoid gas/oil leakage at high temperature.
4. Wide metal compatibility: Firmly bonds carbon steel, cast iron, stainless steel, aluminum alloy and galvanized steel; resistant to engine oil, diesel, high-temperature flue gas, coolant and weak corrosive media.
5. Excellent thermal cycling stability: Locking and sealing performance remains stable under repeated temperature changes, perfectly suited for internal combustion engines and thermal equipment.

Main Applications

1. Heavy trucks & coaches: Permanent fastening for high-temperature bolts on exhaust manifolds, turbochargers and hot gearboxes;
2. Thermal power industry: Thread sealing for boilers, steam pipelines and hot air blower flanges;
3. Mining machinery: Fastener locking for heated sections of crushers and high-temperature hydraulic systems;
4. Lifelong maintenance-free assembly for hot-end fasteners in metallurgy, petrochemical plants and generator units.
