Bitumen 85/35: Optimized Performance for Challenging Industrial Environments

What Makes Bitumen 85/35 Different?

In the modern industrial landscape, not every bitumen grade is engineered for both flexibility and resilience. Bitumen 85/35 stands out due to its perfectly balanced composition—offering a higher softening point and a more moderate penetration rate, making it the go-to solution for demanding sealing, waterproofing, and insulation needs.

Distinctive Technical Features

• Softening Point: 85°C – Remains solid and stable under high temperatures, resisting flow and deformation.

• Penetration: 35 dmm – A mid-range value providing both flexibility and toughness, allowing adaptation to temperature changes and mechanical stress.

• Durability: Excellent resistance to weathering, UV rays, and repeated loading.

• Chemical Stability: Protects structures and materials from acids, alkalis, and industrial contaminants.

• Strong Adhesion: Ensures a reliable bond to a wide variety of surfaces, from metal and concrete to masonry.

• Low Water Permeability: Forms a highly effective moisture barrier for above-ground and below-grade use.

Application Highlights: Where Bitumen 85/35 Excels

1. Industrial and Commercial Roofing

Bitumen 85/35 is a trusted material for both single and multi-layer waterproofing systems. Its unique balance of rigidity and pliability ensures long-term leak protection, even in climates with significant temperature fluctuations.

2. Protective Pipe and Tank Coatings

The chemical resistance and adhesion of Bitumen 85/35 make it ideal for coating pipelines, storage tanks, and metallic structures exposed to water, salts, and industrial fluids.

3. Expansion Joint Sealant

Bitumen 85/35 fills joints in bridges, roads, and industrial floors, providing a weatherproof and flexible seal that accommodates structural movement without cracking.

4. Damp-Proofing for Concrete

Widely used in foundation walls and slabs, 85/35 blocks the capillary rise of moisture, protecting structures from long-term water damage.

5. Electrical and Battery Manufacturing

With its stable electrical properties and thermal resistance,85/35 is frequently used in the insulation of cables, battery sealing, and as a protective layer for electrical assemblies.

Practical Application & Handling Tips

• Surface Preparation: Clean and dry surfaces prior to application for maximum adhesion.

• Melting & Heating: Gently heat Bitumen for application, avoiding excessive temperatures to maintain product quality.

• Method of Application: Can be applied with a brush, mop, trowel, or through automated spraying systems for coatings and membranes.

• Curing: Allow for proper cooling and setting before exposing to heavy traffic or load.

Manufacturing Focus: Precision by Basekim

At Basekim, Bitumen 85/35 is manufactured under rigorous quality control using cutting-edge processes:

• Raw Material Selection: Only high-grade base bitumen, tested for purity and consistency, is accepted.

• Air Oxidation Process: Heated bitumen is subjected to carefully controlled air blowing at 230–270°C. This process precisely adjusts the chemical structure, locking in the 85°C softening point and 35 dmm penetration.

• Continuous Quality Testing: Every batch is tested for penetration, softening point, ductility, and chemical resistance to ensure reliable, uniform product quality.

• Packing: The finished product is promptly packaged to preserve its technical properties for safe storage and worldwide shipping.

Packaging and Worldwide Delivery

85/35 can be supplied in multiple packaging solutions, tailored for industrial projects of any scale:

• Steel Drums: 180–200 kg, durable and suited for export.

• Meltable Polyethylene Bags: 25–50 kg, for direct use in industrial mixing.

• Jumbo Bags: 500–1000 kg, for bulk shipments to large construction and manufacturing sites.

• Custom Packaging: Options available based on specific customer or project requirements.

All deliveries come with comprehensive export documentation, technical support, and safety data sheets.
