Oxidized bitumen is widely used as a protective coating for industrial infrastructure, providing reliable corrosion protection and waterproofing for pipelines, tanks, steel structures, and concrete surfaces. Its excellent adhesion, chemical resistance, and impermeability make it an ideal choice for protecting critical infrastructure from corrosion, chemical attack, and environmental degradation.

The Role of Protective Coatings

Protective coatings are essential for extending the service life of industrial infrastructure. They prevent corrosion, protect against chemical attack, and provide a barrier against moisture and environmental contaminants. Oxidized bitumen coatings deliver these benefits through their unique combination of properties.

Key Protective Coating Applications

Pipe Coating and Wrapping
Oxidized bitumen is used for pipe coating and wrapping, providing corrosion protection for buried and submerged pipelines. It is used to line steel pipes, functioning as a hard, water-impervious barrier.

Steel Structure Protection
Oxidized bitumen is used as a protective coating for steel structures, tanks, and industrial machinery, preventing corrosion and extending service life.

Concrete Protection
Oxidized bitumen is used to protect concrete structures from chemical attack and water infiltration.

Corrosion Protection for Metals
Oxidized bitumen is used in asphalt-based paints for corrosion protection of metals.

Pipeline and Tank Coatings
Bituminous coatings provide long-term protection for pipelines, tanks, and other industrial equipment.

Protective Coating Applications

Grades Used in Protective Coatings

• 85/25: General protective coatings

• 90/40: Heavy-duty protective coatings

• 115/15: High-temperature protective coatings

Performance Requirements

Effective protective coatings must meet several performance requirements:

Adhesion
Strong adhesion to the substrate is essential for long-term protection.

Impermeability
The coating must be impermeable to water and aggressive chemicals.

Chemical Resistance
Resistance to acids, alkalis, and other corrosive substances.

Thermal Stability
The coating must maintain its properties at operating temperatures.

Durability
The coating must provide long-term protection without degradation.
