Basic Specifications
1. Brand: TONSAN, subsidiary brand of H.B.Fuller USA
2. Appearance: Thixotropic silicone paste, anti-sagging on vertical surfaces
3. Curing System: Neutral moisture curing at room temperature, single-component ready-to-use
4. Key Feature: Excellent resistance to lubricating oils
5. Continuous Operating Temperature: -54℃ ~ 210℃
6. Equivalent Product: Loctite 587 silicone flange sealant
Key Advantages
1. Outstanding oil resistance: Cured silicone remains stable immersed in engine oil and gear oil permanently, no swelling or softening, effectively eliminates oil leakage from flange joints.
2. Flexible performance under extreme temperatures: Remains elastic down to -54℃, no sagging or degradation at 210℃ under continuous service.
3. Anti-sagging thixotropic formula: No dripping on inclined engine surfaces, can fully replace traditional paper and rubber gaskets.
4. Non-corrosive neutral curing: Safe for aluminum alloy, cast iron and all metal engine housings without rust risk.
5. Gap compensation ability: Fills flange gaps up to 0.6mm, absorbs thermal expansion and vibration deformation for long-term leak-tight sealing.
Main Applications
