    What is Bitumen 90/10?

    Bitumen 90/10 is one of the hardest grades in the oxidized bitumen range, characterised by a very high softening point of 90–100°C and an ultra-low penetration of just 10–20 dmm.

    This combination places the product firmly at the “hard end” of the industrial bitumen spectrum, making it ideal for applications where the highest possible resistance to heat deformation and mechanical abrasion is required.  With a softening point of 90–100°C, Bitumen 90/10 offers substantial performance margins above the maximum operating temperatures of most buried pipelines, refinery infrastructure, and petrochemical plant coatings.

    Its ultra-low penetration produces a coating film of exceptional hardness, with minimal risk of sagging, dripping, or abrasive wear during pipeline installation by trenching or trenchless methods.

    This grade is widely specified in GCC, MENA, and South Asian pipeline projects where aggressive soil chemistry, high ground temperatures, and demanding cathodic protection requirements converge.

    Applications of Bitumen 90/10

    Extreme Heat Resistance

    Very high softening point (90–100°C) — one of the highest in the oxidized bitumen range for extreme thermal environments

    Ultra-Hard Surface Strength

    Ultra-low penetration (10–20 dmm) produces an exceptionally hard, non-tacky coating film resistant to indentation and abrasion

    Superior Chemical Protection

    Excellent chemical resistance to aggressive soils, groundwater, and dilute industrial chemicals

    Cathodic Disbonding Resistance

    Strong resistance to cathodic disbonding for compatibility with active cathodic protection (CP) systems

    Advantages of Bitumen 90/10

    Suitable for application on live pipelines operating at surface temperatures up to 80°C

    High-Temp Pipeline Coating

    High-temperature buried steel pipeline external anti-corrosion coating (oil, gas, water)

    AWWA C203 Coating

    Bituminous enamel coating to AWWA C203 for steel water transmission mains

    District Pipeline Coating

    External coating for district cooling and district heating pipelines

    Petrochemical Protection

    Protective coating for petrochemical plant structural steel and equipment bases

    Tank Exterior Coating

    Anti-corrosion lining for above-ground steel storage tanks (external surfaces)

    Bridge Steel Protection

    Protective coating for bridge beams and steel substructure elements in aggressive environments
