Basic Specifications
1. Appearance: Red thixotropic liquid, anti-sagging during vertical dispensing
2. Curing System: Anaerobic curing, crosslinks at room temperature between oxygen-free mated metal threads; single-component ready-to-use formula
3. Applicable Thread Size: Standard metal bolts M6 ~ M20
4. Unique Feature: Fully curable on surfaces with thin residual oil film
5. Brand: TONSAN (Sub-brand of H.B.Fuller USA), equivalent to Loctite 243
6. Standard Package: 50ml plastic bottle
Key Advantages
1. Excellent oil tolerance: Cures reliably even with thin residual engine oil/gear oil on thread surfaces, thorough degreasing is not required, greatly simplifying assembly procedures for oily components such as engines and gearboxes.
2. Medium-strength removable locking: Balanced clamping force prevents loosening caused by vibration; easy disassembly with standard hand wrenches without heating during routine maintenance.
3. Anti-sagging thixotropic formula: No dripping on inclined or overhead surfaces inside narrow equipment cavities.
4. 3-in-1 thread protection: Vibration loosening prevention, fluid leakage sealing and rust inhibition, replaces traditional spring washer anti-loosening structures.
5. Stable chemical & thermal resistance: Continuous service temperature ranges from -60℃ to 150℃, durable against oil, coolant and moisture under repeated temperature cycling.
Main Applications
Locking and sealing for bolts on engines, transmission shafts, gearboxes, rocker arms and construction machinery;
Ideal for anti-loosening assembly of slightly oily fasteners on automobile powertrains, excavators and loaders.
