H.B.Fuller TONSAN TS112

Core Product Features
1. Steel-specific formula with perfect color matching
Filled with high-purity alloy steel powder, the repaired area matches the color of carbon steel, alloy steel and stainless steel perfectly, achieving integrated visual effect for exposed equipment housings and precision steel parts.
2. High-strength cold welding without base metal damage
Powerful bonding strength replaces hot electric welding entirely, avoiding welding deformation, stress cracking and annealing damage of steel substrates. Thixotropic putty prevents sagging on vertical and overhead surfaces for on-site quick maintenance.
3. Support precision secondary machining after curing
High hardness and zero shrinkage after curing allows turning, milling, drilling, grinding and boring, accurately restoring tolerance for worn bearing seats, shaft holes and flanges.
4. Excellent wear resistance & medium stability
Dense cured layer resists engine oil, weak acid & alkali, moisture and light oil contamination. Great abrasion and shock resistance ensures long-term reliable operation under dynamic heavy load.
5. Dual function of defect filling and anti-rust protection
Seals blowholes, sand holes, shrinkage cavities and cracks of steel castings to block liquid penetration, repairs rust pits and forms a long-term protective layer against re-oxidation.

Application Scenarios
1. Foundry rework: Repair casting defects such as porosity, shrinkage holes and cracks on carbon steel, alloy steel and stainless steel castings;
2. Transmission component restoration: Recover worn bearing housings, scratched journals, damaged keyways and out-of-tolerance flanges;
3. Pump & valve equipment: Cold repair and leak stoppage for corroded or cracked stainless steel pump bodies, valve bodies and pipeline shells;
4. Heavy machinery maintenance: Emergency repair for cracked, scratched and corroded steel machine beds, gear boxes and engineering mechanical steel structures.
