- Repairs of engine blocks, gears, and pump casings
- Reclaiming surfaces requiring precision finish
Tuff Metal® Steel Putty:
Steel Putty is the workhorse of the cold welding products, this steel filled putty is recommended for making cost-saving repairs on metal parts all over the plant. It is applied without special tools, heat or pressure. It bonds to metals, concrete, and wood.Applications:
- Sealing cracked in castings, tanks, vessels and valves
- Patching defects in steel parts
- Repairs/reclamation of metal parts.
- Repairs/reclamation of metal parts.
Tuff Metal® Fast cure Steel Putty:
Fast Cure Steel Putty is a steel-reinforced, two-part 100% epoxy system that sets within 4 minutes and cures within 10 minutes. It is applied without special tools, heat or pressure and can be machined, drilled, or tapped with conventional metalworking tools. This product offers excellent resistance to oil and gases and bonds to metals, concrete and wood.Applications:
- Arresting online oil leakages from gearboxes/transformers.
- Arresting gas leakages from pipelines/ gas holders.
- Emergency repairs such as gas, air, water, oil leakages from turbine, pipes, tanks.
Tuff Metal® Metal Magic Steel Stick:
METAL MAGIC STEEL STICK is a versatile product used in industrial maintenance it can be applied like putty with a metal finish. No mixing is required, only cut-knead-apply.Applications:
- Any emergency repairs such as water, gas & oil leakages.
- Repairing water and condensate leakage from Gas pipelines/gas holder/ neoprene membrane, arrest leakage of SF6 gas.
- Smoothens welds.
- Repairs holes in elbows, cracks in castings.
Composite repairs are designed as per the corrosion and thickness depletion in assets and Protective coatings always form an integral part:
Chemguard:
Chemguard is a specially developed Vinyl ester base coating offering excellent chemical resistance and is suitable for many coating applications in coating industries. It is also used in the aggressive atmosphere and spillage conditions.Advantages:
- Resistant to salty atmospheric weather even at high temperature.
- 100% solids
- Excellent resistance to Concentrated acids/ alkalies pH (2-10).
- Good resistance with solvents and hydrocarbons.
- Excellent resistance to Aggressive chemicals/ Concentrated Acids & Alkalies.
Applications:
- Internal coating of Chemical tanks like demineralised water tanks, molasses tanks, effluent treatment plants etc.
- Coating of structures, beams, and channels exposed to an aggressive environment.
- Coating of any types of equipment coming into contact with strong corrosive chemicals.
KOROGUARD®:
KOROGUARD® is a specially developed epoxy-based high-performance anti-corrosive coating with excellent chemical, acid and alkali resistance. The product is completely free from volatile ingredients and is suitable for a variety of substrates like Mild Steel, Concrete etc. The speciality coating system when applied by brush or spray over the duly prepared metal/ concrete surface provides a long-lasting anti-corrosive layer thus protecting the same from corrosion and chemical attacks.Advantages:
- Non-shrinking.
- Chemical resistant.
- 100% solid epoxy system, the complete absence of volatile ingredients.
- Higher dry film thickness.
Applications:
- Coating of tanks of Demineralised water, Molasses, Neutralization pits etc.
- Coating of gates submerged in water.
- Coating of structural beams, channels .pipelines etc. exposed to aggressive environment.
Polyurethane coating
Polyurethane coating is a solvent-free two-component hybrid polyurea composite which is fast curing system and excellent in bridging concrete gaps.
Applications of Polyurethane coating:
- Quenching car
- Digester coating& leakage arresting
