Basic Specifications
1. Brand: TONSAN, industrial adhesive brand under H.B.Fuller USA
2. Appearance: Thixotropic silicone paste, anti-sagging on vertical & inclined surfaces
3. Curing System: Neutral moisture curing at ambient temperature, single-component ready-to-use formula
4. Core Property: Excellent resistance to lubricating oil and hydraulic fluid
5. Continuous Service Temperature: -54℃ ~ 260℃ (Maximum heat resistance in this product line)
6. Compatible Substrates: Cast iron, aluminum alloy, carbon steel and all metal flange housings
Key Advantages
1. Dual performance of ultra-high heat resistance & permanent oil resistance: Maintains stable elasticity up to 260℃ continuously without degradation; no swelling or dissolution when immersed in engine oil, gear oil and hydraulic oil, ideal for high-temperature fluid equipment.
2. Stable flexibility under extreme temperature range: Remains crack-free at -54℃, sealing performance will not decline under repeated thermal cycling.
3. Anti-sagging thixotropic formula: No dripping during vertical application, fully replaces traditional paper and rubber gaskets.
4. Non-corrosive neutral curing: No acidic volatiles generated, safe for precision aluminum and cast iron equipment housings.
5. Gap filling capacity: Compensates assembly gaps up to 0.6mm, absorbs vibration and thermal deformation to prevent oil, water and air leakage permanently.
Main Applications
Flange sealing for mating surfaces of reducers, water pumps, valves, internal combustion engines and hydraulic machinery;
Widely applied for leak-proof assembly on heavy-duty reduction boxes, hot water pumps, high-temperature pipeline valves and hot-end casings of diesel engines.
