Bitumen 85/25: Proven Performance for Specialized Industrial Demands

The Value of Bitumen 85/25

In specialized industrial and construction sectors, material consistency and performance directly impact project outcomes. Bitumen 85/25 is formulated for those who require robust reliability and proven results. As an oxidized bitumen with a high softening point and optimal flexibility, Bitumen 85/25 is trusted by contractors, engineers, and manufacturers worldwide for critical infrastructure and manufacturing applications.

Key Performance Features at a Glance

• Softening Point: 85°C – Ensures the material stays solid and stable under higher temperatures, preventing flow or sag in hot conditions.

• Penetration: 25 dmm – Delivers a medium-hard profile, balancing strength with workable flexibility.

• Water & Chemical Resistance: Shields against aggressive industrial liquids, salts, acids, and moisture, supporting longevity even in tough settings.

• High Bonding Strength: Clings securely to concrete, steel, and construction materials for dependable protection and sealing.

• Aging Stability: Maintains core properties under UV exposure, temperature swings, and mechanical stress.

Use Cases: Where Bitumen 85/25 Outperforms

Bitumen 85/25 is engineered for situations that require both durability and adaptability, making it ideal for:

1. Heavy-Duty Roofing Systems

Bitumen 85/25 is a prime choice for flat and sloped industrial roofs. Its high softening point resists deformation from sun exposure, while its bonding capability ensures leak-free membranes and felts.

2. Structural Waterproofing

For bridges, tunnels, and below-grade foundations, 85/25 acts as a powerful water barrier—protecting against capillary water movement and aggressive soil chemistry.

3. Pipe and Tank Protection

Its chemical resistance and adhesion make 85/25 an excellent coating for pipelines and metal tanks, preventing corrosion in oil & gas, water, and industrial facilities.

4. Expansion Joint and Crack Fillers

Its semi-flexible profile is ideal for filling pavement and bridge expansion joints, preventing water ingress and accommodating limited structural movement.

5. Electrical & Battery Industry

Used as a dielectric material and sealing compound, 85/25 provides thermal stability and electrical insulation in battery casings and cable sheaths.

Application Guidelines: Best Practices for Using Bitumen 85/25

• Surface Preparation: Clean and dry all surfaces for optimal adhesion. Remove dust, grease, and loose material.

• Heating: If required, heat  85/25 gently to achieve the desired flow and ease of application, avoiding overheating to preserve quality.

• Application Methods: Suitable for brush, trowel, mop, or automated spraying (for coatings). Always apply in uniform, controlled thickness.

• Curing: Allow sufficient cooling/curing time before subjecting to load or environmental stress.

Manufacturing Excellence: How Bitumen 85/25 is Produced by Basekim

At Basekim, manufacturing Bitumen 85/25 is a precision-driven process built on years of expertise and stringent quality control:

• Raw Material Selection: Only premium base bitumen is used, tested for purity and stability to ensure every batch meets our high standards.
